Move over law — Colorado Permit Test

Move over law on the Colorado permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Under the Move Over Law, when you encounter any stationary vehicle on a highway with its hazards flashing you must move over one lane if you can do so safely.

Anybody outside a stopped car is standing in traffic. One empty lane is the difference between a fright and a fatality.

Colorado Driver Handbook, p.27

When you meet a stationary vehicle on a highway with its hazards flashing, if moving over is not safe or you are on a road with one lane in each direction, you must slow to at least 20 mph below the posted speed limit.

On a narrow road there is no lane to give, so the speed is what is left. Twenty under is the figure Colorado sets for it.

If it is not safe or you are traveling on a road that is one lane in each direction, you must slow down to at least 20 mph below the posted speed limit

Colorado Driver Handbook, p.27

The Colorado Move Over Law protects law enforcement, fire, maintenance and other emergency personnel, tow truck drivers and you.

It is not only about police cars. A tow truck driver or somebody changing a tire is in exactly the same position.

On the test

What does the Move Over Law require when passing a stopped vehicle with hazards on?

Move over one lane if you safely can. Anybody outside a stopped car is standing in traffic. One empty lane is the difference between a fright and a fatality. Colorado Driver Handbook, p.27: “When you encounter any stationary vehicle on a highway with its hazards flashing, you must move over one lane if you can do so safely”

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.
