Space to merge — Maine Permit Test

Space to merge on the Maine permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Any time you merge with other traffic, you need a gap of 4 seconds, which gives both you and the car behind you a safe following distance.

Squeezing into a small gap leaves the car behind you tailgating you at once.

Anytime you merge with other traffic, you need a gap of four seconds to merge safely.

Maine Driver’s License Manual, p.89

If you must cross several lanes, change lanes one at a time; stopping to wait until all lanes are clear ties up traffic and may cause a collision.

A car stopped in a travel lane waiting for a clear road is a target for the car behind.

If you must cross several lanes, change lanes one at a time. If you stop to wait until all lanes are clear, you will tie up traffic and may cause a collision.

On the test

What size gap do you need to merge safely with other traffic?

4 seconds. Squeezing into a small gap leaves the car behind you tailgating you at once. Maine Driver’s License Manual, p.89: “Anytime you merge with other traffic, you need a gap of four seconds to merge safely.”

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.
