Malfunctioning and flashing signals — Tennessee Permit Test

Malfunctioning and flashing signals on the Tennessee permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Tennessee law requires that if a traffic signal is not working, the intersection is treated as an all-way stop.

A dark signal gives no one the right-of-way. Treating it as a green for you is how drivers collide in the middle.

Tennessee state law requires that if a signal is not working, the intersection is to be treated as if it were a ll-way stop intersection.

Tennessee Comprehensive Driver License Manual, p.41

A flashing red light is the same as a stop sign.

A flashing red light means stop, look and wait your turn. Slowing and rolling through is how drivers get hit from the side.

Same as stop sign.

On the test

The traffic light at an intersection is out. How must you treat it?

As an all-way stop. A dark signal gives no one the right-of-way. Treating it as a green for you is how drivers collide in the middle. Tennessee Comprehensive Driver License Manual, p.41: “Tennessee state law requires that if a signal is not working, the intersection is to be treated as if it were a ll-way stop intersection.”

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.
