Point #1
Clearing Intersections
Clearing intersections
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.
Why do you clear intersections?
Keeps you alive at intersections.
Point #2
When stopped in traffic
When stopped in traffic
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.
Why do you leave enough space between the front bumper of your vehicle and the rear bumper of the vehicle in front of you when stopped in traffic?
To have escape route.
Point #3
Count one-two-three after vehicle ahead has started to move
Count one-two-three after vehicle ahead has started to move
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.
Why do you count one, two, three after the vehicle ahead has started to move before placing your vehicle in motion?
Keeps you away from billboards.
Point #4
Four to six second following time for speeds up to 30 MPH, 6-8 seconds for speeds over 30 MPH
Four to six second following time for speeds up to 30 MPH, 6-8 seconds for speeds over 30 MPH
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.
Why do you count four to six second following time for speeds up to 30 MPH, 6-8 seconds for speeds over 30 MPH?
Buys Time.
Point #5
Eight to twelve seconds eye-lead time
Eight to twelve seconds eye-lead time
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.
