Interstate traffic flow and speed — Tennessee Permit Test

Interstate traffic flow and speed on the Tennessee permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Try to keep pace with interstate traffic, but do not exceed the posted speed to stay with the flow.

Other drivers speeding does not change the limit, and a ticket or crash still lands on you.

Try to keep pace with traffic on the road, but don’t be lured into exceeding the posted speed to “stay with the flow of traffic.”

Tennessee Comprehensive Driver License Manual, p.69

If you are in the left lane and someone comes up behind you faster, move one lane to your right.

Holding the left lane makes the faster driver tailgate or pass on the right, both risky.

If you are traveling in the left lane and someone comes up behind you at a faster speed, move one lane to your right.

On the test

Traffic around you is going over the posted limit. What should you do?

Keep pace but stay at or under the limit. Other drivers speeding does not change the limit, and a ticket or crash still lands on you. Tennessee Comprehensive Driver License Manual, p.69: “Try to keep pace with traffic on the road, but don’t be lured into exceeding the posted speed to “stay with the flow of traffic.””

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.
