Following distance — New York Permit Test
Following distance on the New York permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Four of every 10 crashes involve rear-end collisions, normally because a person is following too closely.
Tailgating is the most common crash there is. The gap is the cheapest fix for it.
Four of every 10 crashes involve rear-end collisions, normally because a person is following too closely (tailgating).
For a good space cushion a driver should use the two-second rule: select an object near or above the road ahead, and as the vehicle ahead passes it count slowly through two seconds.
Counting turns a guess into a measure. If you get there first, you were too close.
Select an object near or above the road ahead like a sign, tree or overpass.
In bad weather and when following large trucks a driver should increase the count to at least three or four seconds for additional space.
Wet road and a blocked view both cost time. The extra count buys it back.
In bad weather and when following large trucks, increase the count to at least three or four seconds for additional space.
If a driver is followed too closely they should move to another lane if possible, or reduce speed and pull off the road to let the other driver go by.
A tailgater takes away your braking room. Getting them in front gives it back.
If a driver follows you too closely (tailgates), move to another lane if possible or reduce speed and pull off the road to let the driver go by.
A driver should brake early and gently when they prepare to stop or turn, which gives drivers behind plenty of warning.
Early brake lights are a message. A late stab is a surprise the car behind cannot use.
Brake early and gently when you prepare to stop or turn.
A driver should leave escape room to their left and right in case they must change lanes quickly or pull over to avoid a hazard.
Braking is not the only way out. A clear side is the second one.
In case you must change lanes quickly or pull over to avoid a hazard, leave some “escape” room to your left and right.
On the test
What share of crashes are rear-end collisions?
4 in 10. Tailgating is the most common crash there is. The gap is the cheapest fix for it. New York State Driver's Manual, p.47: “Four of every 10 crashes involve rear-end collisions, normally because a person is following too closely (tailgating).”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
