Passing rules — Connecticut Permit Test

Passing rules on the Connecticut permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.

The rules

At 55 mph you need about 10 seconds to pass, so you need a 10-second opening in oncoming traffic and the sight distance to match it.

A pass is a plan about the future. Ten seconds is how far into it you have to be able to see.

At a speed of 55 mph, you need about 10 seconds to pass.
Connecticut Driver's Manual, p.23

At 55 mph you travel over 800 feet in 10 seconds and so does an oncoming vehicle, which means you need over 1600 feet, about one-third of a mile, to pass safely.

Both cars are using the same road at once, so the distance you need is the sum of what each of you covers.

That means you need over 1600 feet (about one-third of a mile) to pass safely.
Connecticut Driver's Manual, p.23

As a general rule, only pass one vehicle at a time.

Passing two means twice the time in the oncoming lane, and the second driver has no idea you are still coming.

As a general rule, only pass one vehicle at a time.
Connecticut Driver's Manual, p.23

Do not pass unless you have enough space to return to the driving lane, and do not count on other drivers to make room for you.

The pass is only finished when you are back in your lane. Starting without that room means finishing in the wrong one.

Do not pass unless you have enough space to return to the driving lane.
Connecticut Driver's Manual, p.23

It is safe to return to the driving lane when you can see both headlights of the vehicle you just passed in your rear-view mirror.

Seeing both headlights means the whole car is behind you. Guessing at it is how a pass clips a fender.

When you can see both headlights of the vehicle you just passed in your rear-view mirror, it is safe to return to the driving lane.
Connecticut Driver's Manual, p.23

Before passing, look ahead for road conditions and traffic that may push other vehicles into your lane, such as people or bicyclists near the road, a narrow bridge, or a patch of ice or a pothole.

Anything that narrows the road ahead takes away the space you were planning to pass through.

Before You Pass. Look ahead for road conditions and traffic that may cause other vehicles to move into your lane. You might lose your space for passing because of: • People or bicyclists near the road. • A narrow bridge or other situation that causes reduced lane width.
Connecticut Driver's Manual, p.23

On the test

How long does passing take at 55 mph?

About 10 seconds. A pass is a plan about the future. Ten seconds is how far into it you have to be able to see. Connecticut Driver's Manual, p.23: “At a speed of 55 mph, you need about 10 seconds to pass.”

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.
