Turning against a red light — California Permit Test
Turning against a red light on the California permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
You may turn right at a red light after coming to a complete stop, unless a NO TURN ON RED sign is posted.
The stop is what buys you the look, and a rolling turn means you never took it.
You may turn right at a red light after a complete stop unless there is a NO TURN ON RED sign.
You may not turn right when you are stopped at a red arrow, and must wait until the light changes to green.
An arrow points at one movement, so a red one is a refusal aimed straight at you.
You may not turn right if you are stopped at a red arrow light. Wait until the light changes to green before making your turn.
You may turn left against a red light only when turning from a one-way street onto a one-way street, and only where no sign prohibits the turn.
On two one-way streets nothing is coming at you from the left, so the turn crosses nobody.
You may turn left against a red light when you are turning from a one-way street onto a one-way street.
Before turning left against a red light, yield to other vehicles, pedestrians or bicyclists who have a green light.
The green belongs to somebody else at that moment, and they are moving on the strength of it.
Yield to other vehicles, pedestrians, or bicyclists who have a green light.
On the test
What must happen before a right turn at a red light?
A complete stop at the line. The stop is what buys you the look, and a rolling turn means you never took it. California Driver’s Handbook, p.18: “You may turn right at a red light after a complete stop unless there is a NO TURN ON RED sign.”
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.
