Changing lanes — New Jersey Permit Test
Changing lanes on the New Jersey permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Before a lane change a driver looks in the rearview mirror, glances behind to check the blind spot and signals.
The mirror misses a car-sized patch beside you. A glance over the shoulder is what finds it.
When a lane change must be made, look in the rearview mirror. Glance behind to check blind spots. Always signal lane changes.
A driver returns to the right lane when well ahead of the vehicle that was passed, once it shows in the rearview mirror.
Cutting back in early takes away the gap the driver you just passed was keeping.
Return to the right lane when well ahead of the vehicle that was passed.
A driver passes or changes lanes when the move can be completed without speeding.
A pass that needs you to break the limit was a pass that did not have room to start with.
Only pass or change lanes if the change can be completed without speeding
On the test
What are the steps before changing lanes?
Mirror, glance at the blind spot, signal. The mirror misses a car-sized patch beside you. A glance over the shoulder is what finds it. New Jersey Driver Manual, p.96: “When a lane change must be made, look in the rearview mirror. Glance behind to check blind spots. Always signal lane changes.”
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.
