Signaling when slowing — Connecticut Permit Test

Signaling when slowing on the Connecticut permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Your brake lights let people know you are slowing down, so always slow as early as it is safe to do so.

Early braking gives the driver behind the same warning you had, which is the difference between a stop and a rear-end crash.

Your brake lights let people know that you are slowing down.

Connecticut Driver's Manual, p.39

If you are going to stop or slow where another driver does not expect it, tap your brake pedal quickly three or four times.

A flicker of brake lights reads as a warning rather than as ordinary slowing, and it gets read sooner.

tap your brake pedal quickly three or four times to let those behind you know you are about to slow down

Connecticut Driver's Manual, p.39

Places where a following driver does not expect you to slow include turning off a road with no separate turn lane, parking or turning just before an intersection, and avoiding something in the road they cannot see.

Each is a slow-down with no obvious cause from behind, which is why the driver behind is not ready for it.

Turning off a roadway that does not have separate turn or exit lanes.

On the test

What tells the driver behind that you are slowing?

The brake lights. Early braking gives the driver behind the same warning you had, which is the difference between a stop and a rear-end crash. Connecticut Driver's Manual, p.39: “Your brake lights let people know that you are slowing down.”

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.
