Other warning signs — Tennessee Permit Test

Other warning signs on the Tennessee permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.

The rules

A FALLEN ROCK sign warns of rocks that may be in the road, not rocks that may strike you from overhead, so watch the roadway, not the hill.

Staring up at the cliff takes your eyes off the rock lying in your lane around the curve.

This sign warns of rocks that may be in the road, not of rocks which may strike you from overhead.

A YIELD AHEAD sign means a yield sign is just ahead that you cannot yet see; start to slow down.

You may have to stop for cross traffic at the yield sign. Slowing now keeps you from arriving too fast to stop.

On the test

Where should you look when you see a FALLEN ROCK sign?

At the road ahead. Staring up at the cliff takes your eyes off the rock lying in your lane around the curve. Tennessee Comprehensive Driver License Manual, p.38: “This sign warns of rocks that may be in the road, not of rocks which may strike you from overhead.”

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.
