Left turn arrow indications — North Dakota Permit Test
Left turn arrow indications 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
At a steady red left-turn arrow, left-turning drivers must stop and wait.
The red arrow means oncoming traffic or crossing traffic has the road, and turning across it invites a crash.
Left-turning drivers must stop and wait.
A steady yellow left-turn arrow warns that the left-turn signal is changing to red.
It gives you a moment to stop or finish clearing before the protected turn ends.
The left turn signal is changing to red.
At a flashing yellow left-turn arrow, you may cautiously turn left after yielding to oncoming traffic and to pedestrians.
The flashing arrow is not a protected turn, so a driver who does not yield turns straight across moving traffic.
You may cautiously turn left after yielding to oncoming traffic and to pedestrians.
While a flashing yellow left-turn arrow is showing, oncoming traffic will typically have a green light.
Knowing the oncoming cars have a green is why you must wait for a real gap before you turn.
Oncoming traffic will typically have a green light.
At a steady green left-turn arrow, left-turning drivers have the right-of-way.
A protected arrow holds the oncoming traffic, so the turn can be made without waiting for a gap.

On the test
What must a left-turning driver do at a steady red left-turn arrow?
Stop and wait at the line. The red arrow means oncoming traffic or crossing traffic has the road, and turning across it invites a crash. North Dakota Noncommercial Driver License Manual, p.16: “Left-turning drivers must stop and wait.”
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.
