Stopping distance — Maine Permit Test
Stopping distance on the Maine permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Total stopping distance runs from the moment you realize you must stop until the car is completely stopped.
Drivers who count only braking forget the ground they cover before the foot reaches the pedal.
Total stopping distance is the distance from the time you realize you must stop until your vehicle is completely stopped.
Perception time is the time it takes you to recognize that you must stop.
The car keeps rolling at full speed while your mind is still working out the danger.
Perception time – the time it takes you to recognize you must stop.
Reaction time, the time to move your foot from the gas to the brake and begin braking, averages about ¾ of a second to 1 second.
At highway speed even one second carries the car many feet before the brakes bite.
The average driver has a reaction time of ¾ to 1 second.
On dry, level pavement, the manual's chart gives a total stopping distance of about 78 feet at 30 mph.
Even at town speeds the car needs about five car lengths to stop.

On dry, level pavement at 60 mph, the total stopping distance is about 18 vehicle lengths (272 feet) by the manual's chart.
A gap that looks roomy at highway speed is often far shorter than the car needs.
60 66 206 272 18
On dry, level pavement at 70 mph, the manual's chart gives a total stopping distance of about 381 feet.
At 70 mph the car needs more than a football field to stop.

On the test
Total stopping distance is measured from when to when?
From realizing you must stop to a full stop. Drivers who count only braking forget the ground they cover before the foot reaches the pedal. Maine Driver’s License Manual, p.81: “Total stopping distance is the distance from the time you realize you must stop until your vehicle is completely stopped.”
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.
