Large trucks no zones — Tennessee Permit Test

Large trucks no zones on the Tennessee permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.

The rules

A truck's blind spots are right in front, on either side, and up to 200 feet behind it.

A car close behind a truck vanishes from its mirrors. If the truck slows or backs up, its driver does not know you are there.

A truck’s blind spots are immediate in front, on either side of the car and up to 200 feet in the rear.

Tennessee Comprehensive Driver License Manual, p.109

The area up to about 20 feet directly in front of a large vehicle is a No-Zone.

A car that cuts in close and slows down leaves a truck no room to stop. The truck driver may not even see it over the hood.

The area approximately up to 20 feet directly in front of a large vehicle is considered a NO-ZONE.

Tennessee Comprehensive Driver License Manual, p.110

A truck going 55 mph takes about 450 feet or more to stop, far longer than a car.

Pulling in front of a truck and braking leaves it no room to stop. It will roll into you long after you have stopped.

A car traveling at 55 MPH can stop in 240 feet however a truck traveling at the same speed of 55 MPH, takes about 450+ feet to stop.

Tennessee Comprehensive Driver License Manual, p.109

If you are stopped behind a truck on an uphill grade, stay to the left in your lane so the driver can see you, and leave extra space in case it rolls back.

A truck starting up a hill can roll back a few feet. A car close behind and out of the mirror's view gets hit.

If you are stopped behind a truck on an uphill grade, stay to the left in your lane so the driver can see you.

Tennessee Comprehensive Driver License Manual, p.109

Because of their large size, trucks and buses often appear to be traveling slower than they really are.

Misjudging a truck's speed can make you pull out in front of it, and it cannot stop the way a car can.

Because of their large size they often appear to be traveling more slowly than their actual speed.

On the test

How far behind a truck can its rear blind spot reach?

Up to 200 feet. A car close behind a truck vanishes from its mirrors. If the truck slows or backs up, its driver does not know you are there. Tennessee Comprehensive Driver License Manual, p.109: “A truck’s blind spots are immediate in front, on either side of the car and up to 200 feet in the rear.”

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.
