Driver fitness — Tennessee Permit Test
Driver fitness on the Tennessee permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Because seeing well is so important, have your eyes checked by an eye specialist every 1 to 2 years.
Eyesight can fade so slowly that you do not notice. A regular exam catches it before you miss a sign or a child in the road.
you should have your eyes checked every year or two by an eye specialist.
If your license shows Restriction Code 01, you must wear corrective lenses at all times when driving, and you can be ticketed and fined if you do not.
The code means you failed the vision test without lenses. Driving without them means you cannot see well enough to drive safely.
If your driver license indicates you must wear corrective lenses (Restriction Code 01) you must wear them at all times when driving.
Avoid dark sunglasses or tinted contact lenses at night; they cut down the light you need to see clearly.
At night there is already little light. Tinted lenses can hide a person in dark clothes until it is too late to stop.

On the test
How often should drivers have their eyes checked by an eye specialist?
Every 1 to 2 years. Eyesight can fade so slowly that you do not notice. A regular exam catches it before you miss a sign or a child in the road. Tennessee Comprehensive Driver License Manual, p.99: “you should have your eyes checked every year or two by an eye specialist.”
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.
