Traffic signals — Missouri Permit Test

A red light tells you to stop at the stop line, the crosswalk, or before the intersection, and unless you are turning right you must wait for green.

Three stopping places, in order. The first one you reach is the one that applies to you.

A red light tells you to stop at the stop line, crosswalk, or before the intersection.

After a complete stop you may turn right on a red light if the way is clear of pedestrians and traffic, unless a No Right Turn On Red sign is posted.

The stop is not optional and neither is the look. The turn is what is permitted, not the rolling.

After making a complete stop, you may turn right on a red light if the way is clear of pedestrians and traffic.

You must not turn right on a red light where a No Right Turn On Red sign is posted.

The sign exists where the turn is more dangerous than it looks, usually because of what you cannot see.

A steady yellow light tells you the signal is changing from green to red, and you must stop unless you are within the intersection or too close to stop safely.

Yellow is not a shade of green. The default is to stop, and the exception is about physics, not haste.

Stop for a steady yellow light unless you are within the intersection or are so close that you cannot safely stop before entering the intersection.

A green light lets you go through the intersection, but you must first yield to traffic and pedestrians who are still in it.

Green means the intersection is yours once it is empty. It does not empty it for you.

A steady red arrow tells you to stop, and you must wait for the signal to turn green or show a flashing yellow arrow before proceeding.

A red arrow governs one movement only, and until it changes that movement is closed.

You must wait for the signal to turn green or a flashing yellow arrow before you proceed.

A steady yellow arrow appears after a green arrow and tells you the protected turn is ending, so be ready to yield to oncoming traffic or to stop.

The protection is being taken away. What was a clear turn is about to become a judgment call.

You must be ready to yield the right-of-way to oncoming traffic or to stop.

A flashing yellow arrow means you may turn but must wait for an adequate gap in opposing traffic, and you must yield to pedestrians.

It is permission to look for a gap, not permission to turn. The judgment stays with you.

A flashing yellow arrow tells you that you are allowed to drive in the direction the arrow is pointing but are required to wait for an adequate gap in the opposing traffic prior to making your turn.

A green arrow tells you that you can drive in the direction it points, provided you are in the proper lane and the way is clear of all traffic and pedestrians.

The arrow clears the opposing traffic. It does not clear the person already crossing.

You must be in the proper lane and the way must be clear of all traffic and pedestrians.

Traffic signals that are dark or not working operate as a four-way stop.

A dead signal is not a free intersection. Every approach stops and takes its turn.

Dark signals, or traffic signals that aren’t working operate as a four-way stop.

Where does a red light require you to stop?

At the stop line or the crosswalk. Three stopping places, in order. The first one you reach is the one that applies to you. Missouri Driver Guide, p.44: “A red light tells you to stop at the stop line, crosswalk, or before the intersection.”
