Chapter 7

Question 1

When in school zone… speed?

Answer 1

Appropriate speed would be at a walking pace - when you see ‘kinderen’ signs

Question 2

Max speed limits within built up area

Answer 2

within builtup area - 50km/h, unless a sign indicates a different speed

Within builtup areas, sections with lower max speed of 30km/h in 30km/h zone and 15m/h in pedestrian priority areas

Question 3

Maximum speed limits outside the builtup areas

Answer 3

Many depending on where you are driving

• Motorways - 130km/h
• trunk roads - 100km/h
• all other roads outside builtup area - 80km/h

-if there are signs indicating lower speed limits, that is the one to go by

Question 4

Max speed on motorways

Answer 4

• 130km/h but there are many places where lower max speed is in force.
• indicated by road signs
• sometimes lower max speed applies 24 hours a day and sometimes only during peak hours

Question 5

Max speed microcars

Answer 5

the speed limit for microcars within and outside the built-up area is 45km/h.

• Same applies to motorized handicapped vehicles
• Allow for this when approaching these vehicles

Question 6

Max speed with trailer

Answer 6

when driving with trailer or caravan - speed limit on all roads outside the builtup area is 80km/h
-if max permitted mass of your trailer or caravan is below 3,500kg, your speed limit on motorways and trunk roads is 90km/h

Question 7

Recommended speeds

Answer 7

There are also recommended speeds

-these are tailored to specific local circumstances

Question 8

Variable speeds

Answer 8

recommended speeds may gradually increase or decrease as local circumstance change
-by sticking to the speeds - get green wave, where all the traffic lights will allow you to pass without having to stop for green light

Question 9

Adjusting your speed

Answer 9

Sometimes necessary for other road users.

• Drive slowly near schools
• drive slowly with bad weather conditions

Question 10

Trying to gain time

Answer 10

-generally driving fast in busy traffic just wastes petrol and increases chance of accident.. doesn’t gain time.

Question 11

Misleading habituation

Answer 11

When on highway for awhile and enter built up area, will have tendency to speed because you have become accustomed to highway speeds. You need to remember to be 50km/h

Question 12

Risks of misleading habituation

Answer 12

• will have a reduced sense of speed
• will be less aware of maintaining a safe following distance
• you will be less aware of risks
• you will become less aware of your own speed

Question 13

Maintaining safe following distance

Answer 13

• Apply two second rule

- on busy motorways, people often don’t keep a safe enough distance from other vehicles

Question 14

Calculating the safe following distance

Answer 14

divide your speed in meters per hour by the number of second in an hour and then multiply the result by 2

Question 15

Rule of thumb for the safe following distance

Answer 15

since calculations are hard while driving…

you can divide your speed in km/h by 2 and add 10% to result.

Question 16

Pulling in after overtaking

Answer 16

if you apply the two second rule and a vehicle pulls in in front of you, make sure to leave a two second gap to the new vehicle in front of you

Question 17

Increasing the safe following distance

Answer 17

In dangerous situations increase the following distance

examples include:

• risk of aquaplaning
• wintry conditions
• steep hills
• fog
• heavily loaded vehicle
• if you are tired

Question 18

Stopping distance

Answer 18

Always be able to stop in time

• if you double your speed, the braking distance increases fourfold.
• total distance you require to come to a standstill is called the stopping distance. (distance you travel during the reaction time + braking time)

Question 19

Reaction time of one second

Answer 19

on average, it takes one second from the moment you realize that you must brake and the moment that you actually apply the brakes - this is the reaction time

-the distance you calculated previously is the distance you travel during the reaction time

Question 20

Braking distance

Answer 20

if brakes are in good working order, you can use this rule of thumb..
(speed in km/h:10) * (speed:10)

ex. at 120km/h, braking distance is 12*12=144 meters

Question 21

Figure out

Answer 21

Reaction times
