Traffic signal lights — Minnesota Permit Test
Traffic signal lights on the Minnesota permit test — 10 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A steady red light means stop at the stop line, before the crosswalk or before entering the intersection.
The three places are a fallback list. The last one is where you can still see what is coming.
A steady red light means “stop.” Stop and wait for the light to change. Come to a complete stop at the stop line, before the crosswalk or before entering the intersection.
A red arrow means stop, and when the arrow turns green you may go in the direction it shows.
The arrow is a light for one movement only, so a green light beside it means nothing for your turn.
A red arrow means “stop.” You must come to a complete stop at the stop line, before the crosswalk or before entering the intersection.
A steady yellow light or arrow means caution, because the signal is about to turn red.
It is the time to stop, not the time to hurry, and everyone crossing is about to get a green.
A steady yellow light or arrow means “caution.” The signal is about to turn red.
Do not enter the intersection on yellow if you can stop safely; if you cannot, go through with caution.
Slamming on the brakes for a yellow is how a driver gets hit from behind.
Do not enter the intersection if you can stop safely before doing so. If you cannot stop safely, proceed through the intersection with caution.
If you are waiting in the intersection to turn and the signal turns red, complete the turn as soon as it is safe and do not back up.
You are already in the intersection, and reversing puts you into the car that pulled up behind.
If you are waiting in the intersection to make a turn and the signal turns from yellow to red, complete the turn as soon as it is safe. Do not back up.
A green light means you may cross when the intersection is clear, yielding to vehicles or pedestrians already in it.
Green gives you the intersection only once whoever was already in it has finished with it.
A green light. You may cross the intersection as soon as it is clear. Yield to any vehicles or pedestrians in the intersection.
On a green light you must yield to oncoming traffic when turning left, and to pedestrians crossing in front of you when turning either way.
A green light is permission to go, not a claim on the crosswalk you are turning across.
When turning left, yield to oncoming traffic. When turning right or left, yield to pedestrians crossing in front of your vehicle.
A green arrow means you can safely turn in the direction of the arrow, protected from oncoming or crossing traffic.
The arrow means the other directions are being held at red, which a plain green never promises.
A green arrow means you can safely turn in the direction of the arrow. Your turn should be protected from oncoming or crossing traffic.
A flashing yellow light or arrow means caution, and a driver turning left must yield to oncoming vehicles close enough to be a hazard.
It is permission to turn when there is a gap, not permission to turn.
If you are turning left or making a U-turn, you must yield to oncoming vehicles that are close enough to be an immediate hazard.
After stopping at a red light you may turn right when the intersection is clear and traffic is permitted to travel that way.
Both conditions matter: a clear intersection, and a road that actually runs the way you are turning.
Right turn on red: After stopping, you may make a right turn when the intersection is clear, if traffic is permitted to travel in that direction.
On the test
Where do you stop at a steady red light with no stop line or crosswalk?
Before entering the intersection. The three places are a fallback list. The last one is where you can still see what is coming. Minnesota Driver’s Manual, p.65: “A steady red light means “stop.” Stop and wait for the light to change. Come to a complete stop at the stop line, before the crosswalk or before entering the 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.
