Avoiding rear end collisions — Oklahoma Permit Test

Avoiding rear end collisions on the Oklahoma permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.

The rules

To avoid rear-end collisions, watch for brake lights on the four or five cars down the line; it will increase your response time.

Seeing brake lights far ahead tells you of a slowdown before the car right in front of you brakes.

Oklahoma Driver Manual, p.45

Shift your foot to the brake pedal as soon as you see brake lights go on ahead, so you can stop if needed.

Having your foot already over the brake cuts the time between seeing danger and stopping.

Watch for shrinking distance between your car and the one ahead; it's a sure sign of danger.

A closing gap means the car ahead is slowing, and you have less time to stop than you think.

Oklahoma Driver Manual, p.45

It's sometimes hard to tell whether a car in the distance ahead is moving or stopped, so compare it to a fixed object.

Drivers often run into a stopped car on the shoulder because it looked like it was moving.

Oklahoma Driver Manual, p.45

If the car ahead of you signals for a left turn, slow down and prepare to stop.

A car turning left often has to stop for oncoming traffic, right in your path.

If the car ahead of you signals for a left turn, slow down and prepare to stop.

On the test

To avoid rear-end collisions, how far down the line should you watch for brake lights?

The 4 or 5 cars ahead. Seeing brake lights far ahead tells you of a slowdown before the car right in front of you brakes. Oklahoma Driver Manual, p.45: “Watch for brake lights on the four or five cars down the line.”

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.
