The Book Flashcards
blind spot
- the area behind you that you’re unable to see in mirror
- an area not visible to the driver
why do you stay well back of large vehicles?
- so the driver can see you in their mirror
- if you can’t see the mirrors, they can’t see you
- you can see past them on either side
give way
junction ahead
circles
give orders
triangles
give warnings
rectangles
give information
when turning right onto a dual carriageway
- check the central reservation is wide enough to stop in, incase you have to wait before joining traffic
- if there isn’t, only emerge when it’s clear both to your right and left
dual carriageway
a road that has a central reservation to separate carriageways
central reservation
an area of land that separates opposing lanes of traffic
at 60mph, your vehicle will travel
27m in one second
what should you do before making a u-turn?
look over your shoulder for a final check
what should you do as you approach a bridge?
slow down
if there is no footpath
be aware of pedestrians on the road
when should you avoid overtaking?
approaching a dip in the road
a curved arrow on the road might mean
- overtaking traffic should move in that direction
- the route that high vehicles should take under a low bridge
yellow line purpose
to make you aware of your speed
what should you do before stopping?
use the mirrors
use mirrors when you see a hazard ahead to…
… assess how your actions will affect the following traffic
when your waiting to turn but your view is obstructed…
… stop and then move forward slowly and carefully for a clear view
when turning you don’t want…
… to cause other road uses to change speed or direction as you emerge
lights purpose
so others can see you more clearly; increases your visibility
stopping in an emergency
keep both hands on the wheel
what should you do when moving off from behind a parked car
check both interior and exterior mirrors
why do cyclists need extra room?
in case they wobble or swerve around a pothole or raised drain
in narrow roads, be aware of…
… entrances to fields where tractors and other farm machinery could be waiting to pull out
you lose your way on a busy road, what’s the best action to take?
turn into a side road, stop and check a map
when do windscreen mirrors cause a serious obstruction to your view?
- when you’re approaching bends and junctions
- when you’re view is obstructed by windscreen mirrors, be especially careful of motorcyclists
when reversing you might need to…
… ask someone to guide you
why are phones hazardous?
people won’t stop speaking to you, even when you’re approaching a hazard; it diverts your attention
how to use satellite navigation without distracting yourself
stop in a safe place before programming the system
always check the info on your medication
might cause drowsiness
when feeling drowsy, how do you make yourself stay alert in the short term
open the window
large vehicles overtaking you
require more time to pass; slow down
at night
- dip your lights when you’re following or meeting another vehicle; don’t want to dazzle other drivers
- if you’re queueing, use your handbrake rather than your foot, as the brake lights could dazzle the drivers behind you
only flash your headlights to
- show other road users you are there
- not for priority, impatience or greetings
if the road is blocked by animals…
… stop and switch off your engine until the road is clear
tailgating
- driving too closely behind another vehicle
- intimidating and distracting for the user in front
- very dangerous; stopping suddenly creates hazards
- you can see less of the road ahead
- often the cause of rear-end collisions and multiple pile-ups
safety margin of
- 2m
- larger with larger vehicles, because they need more room to manoeuvre
If the road user behind is following too closely
- gradually slow down to increase the gap between you and the vehicle in front
- reduces the chances you’ll have to stop suddenly; allows you to spread your breaking over a greater distance
- defensive driving
giving priority to emergency vehicles
- pull over as soon as it is safe
- check that there are no bollards or obstructions in the road that will prevent it from passing
emergency services =
blue flashing light
doctor’s vehicles =
green flashing light
give priority to:
buses that are pulling out from bus stops, as long as you can do so safely
at unmarked crossroads
no-one has priority
don’t encourage pedestrians to cross by waving or flashing at them with the headlights
there may be another vehicle coming
zebra crossing
pedestrian crossing
pelican crossing
if the amber light is flashing, give way to pedestrians already crossing
puffin crossing
- electronically controlled
- sensors ensure that the red light shows until the pedestrian has safely crossed the road
- steady amber (rather than flashing)
toucan crossing
allow cyclists to cross at the same time as pedestrians
staying well back
gives you more time to react
minimum time gap following a vehicle on a wet road
4 seconds
who should obey the diamond-shaped traffic signs?
tram drivers
on a road where trams operate, which vehicle is most at risk from the tram rails?
cycles
tram rails are sometimes
- slippery
- can cause vehicles to become stuck
using the horn
- only to alert others of your presence
- mustn’t be used between 11.30pm to 7am in built-up area, or when you’re stationary
why do we take up the correct position early?
to help other road users know what you intend to do
if a vehicle is flashing its headlights, that may mean it is trying to
overtake
what to do when approaching unmarked crossroads
- slow down and look both ways
- growing foliage may obscure your view
if a bus lane shows no times of operation, what does this mean?
the lane is in operation 24 hours a day
horses can be startled by
the sound of a car engine or the rush of air caused by a vehicle passing too closely
to avoid a horse
you may have to use the other side of the road
if you’re driving a slow-moving vehicle on a narrow, winding road, what should you do?
pull in when safe, to let following vehicles overtake
what does a loose filler cap on your diesel fuel tank cause?
- can make the road slippery for others (especially if it is wet)
- most likely to occur on bends, junctions and at roundabouts
- called ‘diesel spillage’
what style of driving causes increased risk to everyone?
competitive
defensive driving
questioning the actions of other road users, being prepared for the unexpected
remember that an efficient engine
is kinder to the environment
what do you want to keep to a minimum?
exhaust emissions
what must you check are always working properly?
- lights
- brakes
- steering
- the exhaust system
- seat belts
- horn
- speedometer
- wipers
- washers
the tread on car and trailer tyres must be at least
1.6mm deep across the central 3/4 of the breadth of the tyre and around the entire circumference
it’s illegal to drive with tyres that have
cuts or defects in the side walls
dry steering
- when you turn the steering wheel while the car isn’t moving
- can cause unnecessary wear to the tyres and the steering mechanism
to check the conditions of the shock absorbers
‘bounce’ the vehicle; push down hard over each wheel: there should be no more than one rebound when released
what is most important for a mechanic to check regularly?
brakes and steering
anti-lock braking system (ABS)
- should go out when the car’s travelling at 5-10mph
‘brake fade’
- when the brakes become less effective because of overheating
- may happen if you use them continuously (long, steep, downhill)
- use a lower gear to help control speed
balancing
- making sure that the wheels and tyres are adjusted to minimise any vibrations in the vehicle
- the wheels may need balancing if the steering vibrates
brakes may need adjusting if
the vehicle pulls to one side when braking
the driver is responsible for
making sure that children under 14 wear a suitable restraint
who must wear a seatbelt, unless exempt?
adults, children aged 12 or over, and children over 1.35m
children aged from 3 to 12, or less than 1.35m tall
must use a suitable child restraint or adult seat belt
children younger than 3
- must use a suitable child seat
- never fit a rear-facing baby seat in a seat protected by an active airbag
- the airbag must be deactivated first
adjust the head restraint to
help prevent neck injury in a collision
convex mirrors
give a wider view but can make vehicles look further away than they are
when leaving your car on a two-way road at night
- park in the direction of the traffic
- if the speed limit is more than 30mph, switch on your parking lights
hazard warning lights
- warning other road users of a hazard ahead
- e.g. if you’ve broken down
- e.g. queueing traffic on a dual carriageway or motorway
don’t leave the …… in the car
vehicle registration documents
at night, park in a
well-lit area
have a ……. etched onto windows
vehicle registration number
install a ……. to deter thieves
security-coded stereo
you must not leave your vehicle unattended with
the engine running
do not park over a
dropped curb, as this is where wheelchair and mobility scooter users get onto the road or pavement
do not stop or park at the
zigzag lines at a pedestrian crossing; blocks visibility
ecosafety - actives:
- reduce your speed
- avoid rapid acceleration and heavy braking
- use selective gear changing (reduce the amount of time you’re accelerating)
- regular services and tunings
- make sure tyres are correctly inflated
- keep engine revs low
when does your vehicle use the most fuel?
when accelerating
ecosafety - avoids:
- carrying unnecessary loads or leaving an empty roof rack on your car
- over-revving the engine in lower gears
- leaving the engine running unnecessarily
if your vehicle is stationary, and likely to remain so for some time
switch off the engine
‘kickdown’
- a mechanism in automatic cars that gives quick acceleration when needed (e.g. in overtaking)
- excessive use will burn more fuel
- selects a lower gear
keep your car in good condition (serviced regularly) to
- maintain fuel economy
- reduce exhaust emissions
emissions test for MOT
starts after 3 year
vehicle tax
depends on amount of carbon dioxide emitted
disposing of old engine oil and batteries
- take to local-authority site or garage
- battery acid!
- don’t pour into drain
plan an alternative route incase
your original route is blocked
congestion charge
using congested road space
what is badly affected if the tyres are under-inflated?
braking
correct tyre pressures help reduce the risk of
skidding
don’t rev your engine
unnecessarily
driving slowly in traffic
- increases fuel consumption
- causes a build-up of exhaust fumes
humps, chicanes and narrowing
help to reduce traffic speed
traffic calming measures
help to keep vehicle speeds low in congested areas where there are pedestrians and children
catalytic converters
- reduce harmful exhaust gases
- work more efficiently when the engine has reached its normal working temperature
- found on the exhaust system
when checking tyre pressure
tyres must be cold
under-inflated tyres
- cause increased fuel consumption
- more ‘rolling resistance’
- can affect steering
what do you use to top up the fluid level in your battery, and where do you fill it to?
distilled water; to just above the cell plates
some modern batteries are
maintenance-free
when engines are cold they
use more fuel and emit more
what causes excessive or uneven tyre wear?
- faulty braking system
- faults in the suspension
remember that different maps have
different scales
why is it important to be relaxed when driving?
you can concentrate solely on what you’re doing
If your original route is mostly on motorways
- it’s a good idea to plan an alternative using non-motorway roads
- always carry a map with you just in case you need to refer to it
if brake fluid level gets low
- you could crash!
- if it drops below the minimum mark on the fluid reservoir, air could enter the hydraulic system; loss of braking efficiency or brake failure
as the brake pads or shoes wear down
the brake fluid level will drop
what should you do if your ABS warning light stays on
have the brakes checked immediately
if your headrests are positioned too low
it could cause damage to the neck in a crash
worn shock absorbers cause
bouncing when you press down on one of the wings
roof racks increase
- wind resistance
- can be reduced through an aerodynamically designed roof rack
what does the law require you to keep in good condition?
seat belts
what will happen if your car’s wheels are unbalanced?
the steering will vibrate
when there are road humps
reduce speed throughout the road
always check the engine oil level
before a long journey
always try to park
in a secure car park
prevent your radio being stolen by
installing a security-coded radio
what helps you keep your car secure?
vehicle watch scheme
what does ecosafe driving achieve?
improved road safety
what can happen if you have too much oil in your engine?
- oil leaks - excess pressure damages engine seals
- drain it off
gaps
- dry conditions = 2s
- wet conditions = 4s
- icy conditions = 20s
aquaplaning
- when the tyres lift off the road surface and skate on a film of water
- the steering becomes light
- caused by water collecting on the road surface due to heavy rainfall
what to do if aquaplaning occurs
- ease off the accelerator
- don’t brake until your steering feels normal again
if you’ve driven through deep water
test you brakes
dry out your brakes by
pressing lightly on the brake pedal as you drive
if it very hot
- the road surface can become soft
- affects braking and steering
bright sunlight
- can dazzle
- other drivers might not see indicators (may have to give arm signal)
before setting out in freezing conditions
clear ice and snow from windows, lights, mirrors and number plates
when driving in freezing conditions
- reduce speed
- brake gently in plenty of time
- be prepared to stop and clean your windscreen by hand if the wipers can’t keep the windscreen clear
foggy
- reduces visibility
- allow more time for journey
- slow down (can’t see so far ahead)
- increase the gap
- use dipped headlights, even in daylight
fog lights
- if visibility <100m
- switch them off when fog lifts
windy
- high winds can blow you off course
- allow extra room to the side
- check left side as you pass other vehicles
wind has a greater effect on
- high-sided vehicles
- trailers and caravans
- motorcyclists and cyclists
skidding
- when tyres lose grip on the road
- steering becomes light
- caused by how the driver controls acceleration, braking, speed and steering
- increased risk associated with bad road and tyre conditions, wet or icy conditions
reducing the risk of skidding
- low speed (slow down gradually, avoid sudden steering)
- at highest gear you can use effectively
- anti-skid technology (anti-skid system)
anti-lock braking systems (ABS)
- prevents skidding caused by excessive braking
- wheel speed sensors anticipate when a wheel is about to lock, which could lead to skidding
- can keep steering while braking
- wheels are prevented from locking
- doesn’t reduce stopping distance
if you have to brake suddenly while driving a vehicle with ABS
- press footbrake quickly and firmly
- don’t release brake pedal until vehicle has stopped
ABS might not work well if there is
- surface road water
- loose road surface (e.g. gravel)
anti-skid technology
electronic stability functions
electronic stability control (electronic stability programme)
- computer-controlled system; combines the functions of ABS and traction control
- detects loss of traction; automatically makes corrective adjustments to prevent loss of control
- indicator lamp alerts driver when the car is close to its handling limits
contraflow systems
when one or more lanes have a direction of traffic against that of the rest of the carriageway
when you enter a contraflow system, you should
- reduce speed in good time
- choose suitable lane in good time
- keep safe gap
mirrors, signal, manoeuvre…
… position, speed, look
in icy conditions,
tyre grip is reduced
you take up a position opposite to the direction of your turn to
improve view of the road
water on the brakes can act as a
lubricant, reducing efficiency
soft road surfaces affect
tyre grip; corners and braking
what is average stopping distance in good, dry conditions
53m
at 60mph dry conditions, stopping distance =
73m
at 70mph dry conditions, stopping distance =
96m
at 40mph dry conditions, stopping distance =
53m
stopping distance is affected by:
- type, model and condition of vehicle
- road and weather conditions
- reaction time
50mph, good conditions. braking distance =
38m
50mph, good conditions; thinking distance =
15m
dangers of a contraflow:
- travelling close to oncoming traffic
- narrow lanes
factors increasing likelihood of skid:
- condition of the vehicle (tyres!)
- road condition
- weather conditions
to correct a skid
steer into it carefully (don’t overcorrect!)
torque
- turning force
- increased by starting off in a low gear in the snow
- increase means tyres lose grip easier, and wheels spin
to move off in the snow
use a higher gear than normal
benefit of four-wheel drive
improved grip
chock
- prevents any forward movement
- can leave your car in gear while parking on a hill
when parking your vehicle facing downhill
turn the steering wheel towards the curb
if you have anti-lock brakes, how do you apply the footbrake in an emergency
rapidly and firmly
if in doubt over time gaps
chose 2 seconds
coasting
- travelling for long distances in neutral (or with the clutch down)
- the engine can’t drive the wheels or stabilise you though a corner
- no engine braking
- reduces control
slow moving vehicles have
amber lights
categories of hazard
- static (parked cars, junctions or roundabouts)
- moving (pedestrians, cyclists or drivers)
- road and weather conditions
- you! (alertness, fitness)
static hazards
- bends
- junctions
- roundabouts
- parked vehicles and obstructions in the road
- roadworks
- road surfaces
- different types of crossings
- traffic lights
At level crossings with traffic light signals:
you MUST stop before the barrier when the red lights are flashing, even if the barrier isn’t yet down
potential hazards: parked vehicles
- children running
- vehicle doors opening
- vehicles moving away
potential hazards: junctions
- reduced view
- look for reflections in windows
- don’t block them!
- beware closed lanes
At a traffic-light-controlled junction where the lights aren’t working:
- treat it as an unmarked junction
- be prepared to stop
- may be police officers controlling traffic in these circumstances – make sure that you know and understand their signals.
slow-moving or stationary vehicles with a large arrow displayed on the back show
where you need to change lanes when approaching roadworks
when travelling in slow traffic, before you turn left…
check for cyclists filtering through the traffic on your left
watch out for motorcyclists when:
- emerging from a junction
- turning into a road on your right
- changing lanes or moving out to overtake
at some bridges, high vehicles may need to
use the centre of the road to be able to pass underneath
at bus stops
- pedestrians may cross the road
- it may be about to move off
school buses
may stop in places other than bus stops
large goods vehicles over 13m long
have red and yellow markings at the back
when turning right, don’t forget to
check your right for overtaking vehicles before making the turn
powered vehicles for the disabled
are extremely vulnerable because they are difficult to see, and travel slowly
help your awareness by
using your mirrors
alcohol can:
- reduce your concentration, coordination and control
- give you a false sense of confidence
- reduce your judgement of speed
- slow down your reactions
illegal drugs can have an effect for
72hrs
tinted glasses
- can restrict your vision
- must not be worn at night
black rectangular sign with white triangular arrows facing left (or right)
sharp turn left (or right)
one yellow light signals a
school crossing patrol
when the amber light comes on at the level crossing
you have to stop
never overtake near a
junction
as you approach a bus stop
look to see how many passengers are waiting to board
some two-way roads are divided into three, allowing
drivers from both direction to use the middle lane to overtake
an amber flashing light on a vehicle means that it is
slow-moving
a policeman making an L with their arms means
stop
a solid white line at the side of the road indicates
- the edge of the carriageway
- especially useful when visibility is restricted
staggered junctions
- traffic could be turning off or pulling out ahead of you, to the left or right
- be aware of vehicles slowing down/stopping
in a one-way street, it is illegal to
reverse or turn around
it is okay to sound your horn if
another driver is reversing (for example, out of a driveway), where you have priority, and they haven’t seen you
tinted glasses
reduce the efficiency of your vision by reducing the amount of light reaching your eyes
if your vision has become very poor but your optician can’t help you, who must you tell? The same applies for ill health.
The driver licensing authority (DVLA)
when driving in the rain…
be aware of spray reducing your vision
you should never stop on the hard shoulder
for rest
if a policeman is directing you with one hand up in the air
stop until signalled to go on
you can use bus lanes
never!
factors increasing vulnerability:
- inexperience or lack of judgement
- size
- speed
- unpredictable behaviour
pedestrians are vulnerable because they
- move slower
- no protection in collision
remember that there might not always be
a pavement, or it might be closed for repairs
large groups should have
- a person at the front with a white light
- a person at the back with a red light
pedestrians crossing a side road when you’re turning in
have priority - don’t run them over!!!
signs someone might be about to cross between parked cars:
- seeing their feet when looking between the wheels of the parked cars
- a ball bouncing out into the road
- a bicycle wheel sticking out between cars
children are vulnerable
because they’re unpredictable - less likely to look before stepping into the road
if there are flashing amber lights under a school warning
children are likely to be crossing
a school crossing patrol
might stop the traffic by stepping out into the road with a stop sign
yellow zigzag lines outside a school
don’t wait or park there; a clear view is needed by road users and pedestrians
vulnerable people might
misjudge your speed, need extra time to cross the road
a person with hearing difficulties might have:
a dog with a distinctive yellow or burgundy coat
a person carrying a white stuck with a red band
is both deaf and blind - they might also have a guide dog with a red and white checked harness
cyclists should normally
follow the same rulers of thread as drivers; slower speed and lack of protection means vulnerability
