Following distance seconds — Arizona Permit Test

Following distance seconds on the Arizona permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Allow at least a 3-second following distance for most driving situations.

If traffic ahead stops suddenly, the gap is your only time to see it and brake. Too close and you hit the car in front.

Allow at least a 3-second following distance for most driving situations.

On slippery roads, double your following distance to 6 seconds or more.

On a slick road the tires grip less, so it takes much longer to slow down or stop. A normal gap is not enough.

When driving on slippery roads, you should double your following distance to 6 seconds or more to allow for the extra distance needed to adjust your speed or to stop.

When the driver behind you wishes to pass, slowing down lets that driver pass more quickly.

Speeding up keeps the passing car out in the other lane longer, facing oncoming traffic. Easing off gets it back in sooner.

When the driver behind you wishes to pass, reducing your speed will allow that driver to pass more quickly.

When following a large vehicle such as a tractor-trailer that blocks your view of the road ahead, you need extra distance to see around it.

Tucked close behind a big truck, you cannot see the stopped traffic or debris the truck is about to reach.

vehicle, such as a tractor-trailer, that blocks your field of vision of the road ahead, you will need extra distance to see around the vehicle.

On the test

What following distance does the manual say to allow for most driving situations?

At least 3 seconds. If traffic ahead stops suddenly, the gap is your only time to see it and brake. Too close and you hit the car in front. Arizona Driver License Manual and Customer Service Guide, p.53: “Allow at least a 3-second following distance for most driving situations.”

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.
