Minimum speed rules — New Mexico Permit Test

Minimum speed rules on the New Mexico permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.

The rules

No one should drive slower than the posted minimum speed; if no minimum is posted, drive so you do not get in the way of normal traffic flow.

A car going far slower than everyone else makes drivers brake hard or pass, which leads to crashes.

If no minimum is posted, drive so that you do not interfere with regular traffic flow.

New Mexico Driver Manual, p.12

When you are driving slower than other vehicles, travel on the right-hand side of the road.

Staying right lets faster cars pass you on the left, where they expect to pass.

On the test

No minimum speed is posted. How slow may you drive?

Not so slow you block normal traffic. A car going far slower than everyone else makes drivers brake hard or pass, which leads to crashes. New Mexico Driver Manual, p.12: “If no minimum is posted, drive so that you do not interfere with regular traffic flow.”

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.
