Changing lanes safely — North Dakota Permit Test
Changing lanes safely on the North Dakota permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
If possible, avoid changing lanes within an intersection.
Cars turn and pedestrians cross in an intersection, and a lane change there adds one more path to cross.
If possible, avoid changing lanes within an intersection.
Before changing lanes, check your mirrors and look over your shoulder for vehicles behind you and already in the other lane, because mirrors have blind spots.
Mirrors miss a car riding just off your rear corner, and only a turn of the head shows it.
Check your mirrors and look over your shoulder for vehicles behind you and already in the other lane.
A blind spot is an area where your mirrors fail to pick up approaching traffic.
Knowing what a blind spot is tells you why a clear mirror does not prove a lane is empty.
Be aware of “blind spots” or areas where mirrors fail to pick up approaching traffic.
Change only one lane at a time, and cancel your signal when you complete the lane change.
Crossing several lanes at once surprises drivers two lanes over, and a signal left on tells others you are about to move again.
Change only one lane at a time and be sure to cancel your signal when you complete the lane change.
The driver of the vehicle making the lane change is responsible for changing lanes safely.
Drivers already in the lane have no warning of your move, so the duty to make it safe is yours.
Remember: The driver of the vehicle making the lane change is responsible for safely changing lanes.
On the test
Where should you avoid changing lanes if possible?
Within an intersection. Cars turn and pedestrians cross in an intersection, and a lane change there adds one more path to cross. North Dakota Noncommercial Driver License Manual, p.21: “If possible, avoid changing lanes within an intersection.”
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.
