Changing lanes — Connecticut Permit Test

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

The rules

Changing lanes includes moving from one lane to another, merging from an entrance ramp, and entering the roadway from the curb or shoulder.

Pulling out from the curb is a lane change, and a driver who does not think of it that way skips the checks.

Changing lanes includes: moving from one lane to another, merging onto a roadway from an entrance ramp, and entering the roadway from the curb or shoulder.
Connecticut Driver's Manual, p.23

Before changing lanes, look in the rear-view and side mirrors and make sure there are no vehicles in the lane you want to enter.

The mirrors answer most of the question. They are the first check, not the only one.

Look in your rear-view and side mirrors. Make sure there are no vehicles in the lane you want to enter.
Connecticut Driver's Manual, p.23

Look over your shoulder in the direction you plan to move, because the rear corners of your vehicle are blind spots the mirrors do not show.

Mirrors miss a whole car at the rear corner. Turning your head is the only way to find it.

These areas are called “blind spots” because you cannot see them through your mirrors.
Connecticut Driver's Manual, p.23

Check the far lane as well, because someone in it may be planning to move into the same lane you want to enter.

Two cars aiming for one gap is how a lane change goes wrong even when both drivers checked properly.

Be sure to check the far lane (if there is one), as someone in that lane may be planning to move into the same lane that you want to enter.
Connecticut Driver's Manual, p.23

To cross several lanes, take them one at a time, because it is very difficult to be sure all of them are free at once.

Clearing four lanes in one movement means betting on four drivers at once, and you can only look at one.

If you want to change several lanes, take them one at a time.
Connecticut Driver's Manual, p.23

Check quickly, and do not take your eyes off the road ahead for more than an instant, because traffic in front could stop while you look aside.

The car ahead does not wait while you check the mirror, and a long look is how a lane change becomes a rear-end crash.

Do not take your eyes off the road ahead for more than an instant.
Connecticut Driver's Manual, p.23

On the test

Which of these counts as changing lanes?

Entering the roadway from the curb. Pulling out from the curb is a lane change, and a driver who does not think of it that way skips the checks. Connecticut Driver's Manual, p.23: “Changing lanes includes: moving from one lane to another, merging onto a roadway from an entrance ramp, and entering the roadway from the curb or shoulder.”

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.
