Q

Clearing intersections

A

Whether approaching, turning, going through, or starting up at intersections scan ahead, look left, right, then back to the left. Scan your driving scene getting the big picture and look left, right, first, looking for any pedestrians, bicycles, motorcycles, and vehicles to ensure they are obeying their traffic sign or signal, and looking for any obstructions that may block your visibility. Look left the second time because that’s the first lane of traffic I’m going to enter. Prior to entering the intersection, I check my traffic side mirror looking for traffic in the lane next to my vehicle that may turn in front of me. As I proceed through the intersection I check my opposite traffic side mirror to ensure I cleared the intersection of any hazards.

Q

When stopped in traffic

A

When stopped in traffic, I leave enough space between the front bumper of my vehicle and the rear bumper of the vehicle in front of me. If that vehicle stalls or becomes disabled, I can maneuver around that vehicle without having to back up in traffic. The space I leave in front of my vehicle is proportionate to the size of my vehicle. The longer my vehicle, the more space required.

Q

Count one-two-three after vehicle ahead has started to move

A

Count one, two, three after the 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

Four to six second following time for speeds up to 30 MPH, 6-8 seconds for speeds over 30 MPH

A

To calculate following distance- When the 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

Eight to twelve seconds eye-lead time

A

Eight to twelve seconds of eye lead time is the 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

Why do you need eight to twelve seconds eye-lead time?

A

Centers car in traffic lane.

17
Q

Point #6

A

Scan Steering Wheels

18
Q

Scan steering wheels

A

Always scan steering wheels of parked cars to see if the vehicle is occupied. An occupied vehicle presents two hazards, the person may either exit the vehicle, or pull away from the curb. Other ways to see if the vehicle is occupied is steering wheels turned out, tail or brake lights on, and exhaust coming from the tail pipe. If you can’t determine if the vehicle is occupied, treat it as an occupied vehicle. A small tap or loud blast if necessary, close enough to be heard, yet far enough away to take evasive action.

19
Q

Why do you always scan steering wheels of parked cars to see if the vehicle is occupied?

A

Take path of least resistance.

Q

Point #7

A

Stale Green Lights

21
Q

Stale green lights

A

A stale green light is a light that I did not see change, and I’m not sure when it may turn to yellow or red. A point of decision must be established between the front bumper of my vehicle and the stop line. If the 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 through the intersection without hesitation or acceleration. Things that affect my point of decision are road, load, weather and speed. (Demo)

22
Q

Why do you treat stale green lights with caution?

A

Smooth stops and turns.

23
Q

Point #8

A

Eye Contact

24
Q

Eye contact

A

Always establish eye to eye contact with pedestrians, bicycles, motorcycles, and vehicles to eliminate uncertainty. We use 3 tools to establish eye to eye contact, our horn, lights and signals. Our horn is the primary tool, 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.

25
Q

Why do we use our horn, lights and signals?

A

Establishes eye to eye contact.

26
Q

Point #9

A

Pulling from curb

27
Q

Pulling from curb

A

When pulling from a 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 curb. I do not deactivate my turn signal until all of my equipment is completely in the lane I am occupying.

28
Q

Why do I always indicate my intentions by turning on my traffic side turn signal, when pulling from a curb?

A

To communicate in traffic.

29
Q

Point #10

A

Use of mirrors and gauges

30
Q

Use of mirrors and gauges

A

I check a mirror every 5 to 8 seconds looking for lane position, traffic conditions and mechanical problems. 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.

31
Q

Why when I check a mirror or gauge my next eye movement is always back to the front and never to go mirror to mirror, gauge to gauge, mirror to gauge, gauge to mirror?

A

To keep eyes ahead of car.
