Turn arrows — Colorado Permit Test
Turn arrows on the Colorado permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A lighted red arrow means you must stop and may not turn in the direction shown.
A red arrow is narrower than a red light: it forbids one movement while the rest of the signal may allow others.
A lighted red arrow means you must stop and may not turn in the direction shown
A lighted green arrow means you may turn in the direction it shows, whether it appears by itself or with a red, green or yellow light.
A green arrow is a protected turn: the traffic that would otherwise be coming at you is being held. That is why it can appear beside a red light.
A lighted green arrow, by itself or along with a red, green or yellow light means you may turn in the direction shown by the arrow
If the green arrow goes off but the circular green is on, you may still turn after yielding to through vehicles and pedestrians, unless a sign or red arrow prohibits it.
The protection has ended, not the permission. The gap you were given has to be found for yourself now.
If the green arrow goes off, but the circular green is on, you may still turn after yielding to through vehicles and pedestrians, unless prohibited by a sign or red arrow
A lighted yellow arrow means a red arrow is about to appear, so stop if you are not already in the intersection.
It is the same warning a yellow light gives, applied to one movement. The red arrow behind it forbids the turn outright.
Yellow arrow: A lighted red arrow is about to appear
A flashing yellow arrow means a driver turning left should proceed with caution and must yield to oncoming traffic and pedestrians.
It looks like permission and is only an opportunity. The cars coming the other way have a green of their own.
A flashing yellow arrow means the driver turning left should proceed with caution and must yield to oncoming traffic and pedestrians
A flashing yellow arrow is followed by a solid yellow telling the driver not to enter the intersection if they can stop safely, and then by red, which means stop.
The sequence gives you a last chance to think rather than dropping straight to red. Knowing what is coming stops the late dash.
The signal will then switch to solid yellow, telling the driver the light is about to turn red and to not enter the intersection if they can stop safely
On the test
What does a lighted red arrow require?
Stopping, with no turn in the direction shown. A red arrow is narrower than a red light: it forbids one movement while the rest of the signal may allow others. Colorado Driver Handbook, p.7: “A lighted red arrow means you must stop and may not turn in the direction shown”
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.
