Signal when slowing — Montana Permit Test

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

The rules

If you will stop or slow where another driver does not expect it, tap your brake pedal three or four times quickly to warn those behind you.

Flashing brake lights catch the eye of a driver behind who would otherwise expect you to keep going.

If you are going to stop or slow down at a place where another driver does not expect it, tap your brake pedal three or four times quickly to let those behind you know you are about to slow down.

Montana Driver Manual, p.58

Signal when you slow down to park or turn just before an intersection, because following traffic expects you to go through it.

The driver behind is watching the light ahead, not you, and does not expect you to stop short of it.

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

Montana Driver Manual, p.58

Signal when you slow down to turn off a road that has no separate turn or exit lanes.

With no turn lane, you slow down in the traffic lane, right in front of cars still at full speed.

Always slow down as early as it is safe to do so.

Montana Driver Manual, p.58

On the test

How do you warn drivers behind you that you will slow where they do not expect it?

Tap the brake pedal 3 or 4 times. Flashing brake lights catch the eye of a driver behind who would otherwise expect you to keep going. Montana Driver Manual, p.58: “If you are going to stop or slow down at a place where another driver does not expect it, tap your brake pedal three or four times quickly to let those behind you know you are about to slow 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.
