High occupancy vehicle and turn lane markings — Tennessee Permit Test

High occupancy vehicle and turn lane markings on the Tennessee permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.

The rules

HOV lanes are marked by a diamond-shaped marking in the center of the lane.

The diamond tells you the lane has rules about who may use it. Driving alone in it at the wrong time can get you a ticket.

High Occupancy Vehicle (HOV) Lanes are designated on highways by a diamond-shaped marking in the center of the lane.

Tennessee Comprehensive Driver License Manual, p.43

If your lane is marked with a curved arrow and the word ONLY, you must turn in the direction of the arrow.

Drivers beside you expect your lane to turn. Going straight from it cuts across their path.

Turn Lane Arrow: If you are traveling in a lane marked with a curved arrow and the word ONLY, you must turn in the direction of the arrow.

Tennessee Comprehensive Driver License Manual, p.43

If your lane is marked with both a curved and a straight arrow, you may turn in the direction of the arrow or go straight.

Knowing you have a choice keeps you from changing lanes at the last moment to go straight.

If your lane is marked with both a curved and a straight arrow, you may turn in the direction of the arrow or you may go straight.

On the test

What pavement marking shows an HOV lane?

A diamond in the lane. The diamond tells you the lane has rules about who may use it. Driving alone in it at the wrong time can get you a ticket. Tennessee Comprehensive Driver License Manual, p.43: “High Occupancy Vehicle (HOV) Lanes are designated on highways by a diamond-shaped marking in the center of the 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.
