Changing lanes checks — Delaware Permit Test

Changing lanes checks on the Delaware permit test — 4 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.

A driver pulling away from the curb without checking behind is changing lanes blind.

Changing lanes includes: changing from one lane to another, merging onto a roadway from an entrance ramp, and entering the roadway from the curb or shoulder.
Delaware Driver Manual, p.118

Before changing lanes, look over your shoulder: the areas near the rear corners of your vehicle are blind spots you cannot see in your mirrors.

A car sitting off your back bumper does not show in either mirror until you turn into it.

Be sure no one is near the rear corners of your vehicle.
Delaware Driver Manual, p.118

When checking traffic before a lane change, check quickly; do not take your eyes off the road ahead for more than an instant.

While you look over your shoulder too long, the car ahead brakes and you run into it.

Do not take your eyes off the road ahead for more than an instant.
Delaware Driver Manual, p.118

Check the far lane, if there is one, because someone there may be planning to move into the same lane you want.

Two drivers from opposite sides can each move into the middle lane at once.

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 you want to enter.

On the test

Which of these counts as changing lanes in the manual?

Pulling onto the road from the curb. A driver pulling away from the curb without checking behind is changing lanes blind. Delaware Driver Manual, p.118: “Changing lanes includes: changing 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.
