Following distance law — Tennessee Permit Test

Following distance law 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 says you may not follow another vehicle more closely than is reasonable and prudent, given the speed, the traffic and the road.

There is no single safe gap for every road. On wet roads or at high speed, you need more room to stop.

Tennessee law states: “The driver of a motor vehicle shall not follow another vehicle more closely than is reasonable and prudent, having due regard for the speed of such vehicles and the traffic upon and the condition of the highway.

Most rear-end crashes are caused by drivers who are tailgating.

A tailgater cannot see past the car ahead. When that car brakes, there is no time left to stop.

Rear-end crashes are very common and most of these crashes are caused by drivers who are “tailgating.

On the test

Under Tennessee law, how closely may you follow another vehicle?

No closer than is reasonable and prudent. There is no single safe gap for every road. On wet roads or at high speed, you need more room to stop. Tennessee Comprehensive Driver License Manual, p.48: “Tennessee law states: “The driver of a motor vehicle shall not follow another vehicle more closely than is reasonable and prudent, having due regard for the speed of such vehicles and the traffic upon and the condition of the highway.”

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.
