Q

Clearing Intersections - explanation

A

When approaching, turning, going thru, or starting up at intersections scan ahead, look L, R, then back to Left. Scan your driving scene to get big picture and look L, R first, looking for any pedestrians, bikes, motorcycles, and vehicles- to ensure they are obeying traffic signals/signs, and looking for any obstructions that may block visibility.
Look LEFT the SECOND TIME because that’s the first lane of traffic I’m going to enter.

Q

Clearing Intersections - prior to entering the intersection you check what mirror?

A

Traffic side mirror first to look for traffic in lane next to my vehicle that may turn in front of me. As I proceed thru intersection I check opposite side traffic mirror to ensure I cleared the intersection of any hazards.

Q

When Stopped in Traffic - explanation

A

I leave enough space between front bumper of my vehicle and rear bumper of vehicle in front of me. If that vehicle stalls or becomes disabled, I can maneuver around without having to back up into traffic. Space I leave in front of my vehicle is proportionate to size of my vehicle.

Q

Count 1-2-3 after vehicle ahead has started to move - explanation:

A

Count 1-2-3 after vehicle ahead has started to move before placing my vehicle in motion. This will automatically establish a space cushion and allow me to bring my eyes up to the driving scene ahead.

Q

4-6 second following time for speeds up to 30mph.
6-8 seconds for speeds over 30mph. -
explanation:

A

To calculate following distance- when vehicle ahead passes a stationary item, start counting 1/1000 one, 1/1000 two, 1/1000 three, until the front bumper of my vehicle reaches that item. This is my following distance in seconds and gives me time to act to any changes in the traffic scene ahead.

Q

8-12 seconds eye-lead time - explanation:

A

8-12 sec eye-lead time is depth of which my eyes should be most of the time while driving. To establish eye-lead time while driving, I pick a stationary item in front of my vehicle and start counting 1/1000 one, 1/1000 two, 1/1000 three, until the front of my vehicle reaches that item. That is my eye-lead time in seconds. Remember that it is a maintained depth of vision.

Q

Scan steering wheels - explanation:

A

Always scan steering wheels of parked cars to see if the vehicle is occupied. Are steering wheels turned out, tail or brake lights on, exhaust coming from tail pipe? If you can’t determine if a vehicle is occupied, treat it as an occupied vehicle. A small tap or blast if necessary, close enough to be heard, yet far enough away to take evasive action.

Q

Stale green lights - explanation:

A

A stale green light is a light that I did NOT see change, and I’m not sure when it will turn yellow or red. A point of decision must be made between front bumper of my vehicle and stop line. If light would change before reaching my decision point I will be able to bring the vehicle to a safe stop behind the stop line. If I reach my decision point and the light would change, I will continue thru the intersection without hesitation or acceleration. Things that affect my point of decision are road, load, weather, and speed.

17
Q

Stale green lights - WHY?

A

Smooth stops and turns.

18
Q

Eye contact - explanation:

A

Always establish eye-to-eye contact with pedestrians, bikes, motorcycles, and vehicles to eliminate uncertainty. We use 3 tools to establish eye to eye contact.

19
Q

What 3 tools used to establish eye-to-eye contact?

A

Horn, lights, signals

20
Q

Which tool is primary tool to establish eye-to-eye contact?

A

HORN. Usually a tap of the horn, sometimes a loud blast is necessary. Once I establish eye-to-eye contact I can expect the other person to act in a reasonable and predictable manner.

21
Q

Eye contact - WHY?

A

Establishes eye-to-eye contact

22
Q

Pulling from curb- explanation:

A

When pulling from curb, I always indicate my intentions by turning on my traffic side turn signal. I check traffic by looking at my traffic side flat and convex mirrors. I look over my traffic side shoulder to check my blind spot between the fuel tank and drive axle in the lane I’m about to occupy. When the lane is clear I can proceed with pulling from the curb. I do not deactivate my turn signal until all of my equipment is completely in lane I am occupying.

23
Q

Pulling from curb - WHY?

A

Communicate in traffic, horn, lights, signals.

24
Q

Use of mirrors and gauges - explanation:

A

I check a mirror every 5-8 seconds looking for lane position, traffic conditions, and mechanical issues. I substitute a mirror check, when traffic allows, with one of my primary gauges - oil or water- looking for normal readings. When I check a mirror or gauge my next eye movement is back to the front. Never go mirror to mirror, gauge to gauge, mirror to gauge, gauge to mirror.

25
Q

Use of mirrors and gauges - WHY?

A

Keeps eyes ahead of car.
