Passing a truck — Vermont Permit Test

Passing a truck on the Vermont permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.

The rules

It takes longer to pass a large truck, so maintain a consistent speed, and be sure you can see the cab of the truck in your inside rearview mirror before returning to the right lane.

Cutting back in early puts you where the truck driver cannot see you and cannot stop for you.

Be sure you can see the cab of the truck in your inside rearview mirror before returning to the right lane.

2025 Vermont Driver's Manual, p.43

Never go around a truck that is preparing to back up or is backing up. Most trailers can completely hide whatever comes between them and a loading area.

The driver has to block the street to line the trailer up, and the space beyond the trailer is invisible to them.

Truck drivers often need to swing wide to the left in order to make a right turn, and they cannot see vehicles directly behind or beside them. Do not cut in between the truck and the curb.

The gap the truck opens on its right is the space the trailer is about to sweep through.

Do not cut in between the truck and the curb or shoulder to the right; this increases the possibility of a crash.

On the test

When is it safe to return to the right lane after passing a truck?

When the truck's cab is visible in the rearview mirror. Cutting back in early puts you where the truck driver cannot see you and cannot stop for you. 2025 Vermont Driver's Manual, p.43: “Be sure you can see the cab of the truck in your inside rearview mirror before returning to the right lane.”

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.
