On the test

What does this sign help you choose?

Your lane and exit. These signs come up fast at highway speed. Reading them early lets you move over before your exit, not at it. Tennessee Comprehensive Driver License Manual, p.40: “Such signs give information vital to selection of lane, proper exits, etc.”

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.
