Changing lanes — Indiana Permit Test

Changing lanes on the Indiana permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Change only one lane at a time, and signal before turning or changing lanes.

Crossing several lanes at once surprises drivers in each lane you cut across.

Change only one lane at a time.

Indiana Driver's Manual, p.37

Before changing lanes, briefly turn your head toward the new lane to check that no vehicle is in your blind spot.

Mirrors leave gaps beside the car where another vehicle can hide.

Briefly turn your head toward the lane that you are entering to make sure that there is no vehicle in your blind spot and that there is sufficient room to move into the adjacent lane

Indiana Driver's Manual, p.37

On the highway, slower vehicles should use the right lane and leave the left lane for faster and passing vehicles.

Keeping right lets faster traffic pass on the left, where drivers expect it.

On the highway, slower vehicles should use the right lane.

Indiana Driver's Manual, p.37

Do not weave in and out of lanes, which greatly increases the risk of a crash.

Each lane change is a chance to hit someone. Weaving adds many of them for little time saved.

Do not weave in and out of lanes, which will greatly increase your risk of an accident.

Indiana Driver's Manual, p.37

On the test

How many lanes should you change at a time?

One lane at a time. Crossing several lanes at once surprises drivers in each lane you cut across. Indiana Driver's Manual, p.37: “Change only one lane at a time.”

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.
