Regulatory signs — Colorado Permit Test

A stop sign means you must come to a complete stop.

A complete stop is the only way to get a proper look both ways. Rolling through means deciding on a glance taken while moving.

These signs mean you must come to a complete stop

At a stop sign you must stop at a clearly marked stop line, or if there is none, before entering the crosswalk on the near side of the intersection.

The line is placed where a driver can see across the intersection. Stopping past it puts your car in the space people are walking through.

You must stop at a clearly marked stop line, but if none, before entering the crosswalk on the near side of the intersection

A yield sign means you must slow or stop to yield to all pedestrians and any vehicle with right of way.

Yield asks for a judgment rather than a stop, so it only works if you slow enough to make one. Sometimes the judgment is that you have to stop.

These signs indicate you must slow or stop to yield to all pedestrians and any vehicle with right of way

Speed limit signs show the maximum or minimum speed allowed, and the maximum limits are for ideal conditions.

The number is a ceiling for a dry road in daylight with light traffic. In anything less it is a speed you are allowed rather than one you should drive.

These signs show the maximum or minimum speed that is allowed

You must reduce your speed below the posted maximum when conditions require it.

A posted limit is not a defense if you crash at it on ice. Conditions set the real limit and the sign only sets the ceiling.

The maximum limits are for ideal conditions and you must reduce your speed when conditions require it

Do Not Enter and Wrong Way signs warn and redirect drivers who are heading the wrong way on streets or freeway ramps, and you must not proceed past one.

These are the last warning before a head-on collision at highway speed. They are placed where somebody has already taken a ramp backward.

These signs warn and redirect drivers who are heading the wrong way on streets or freeway ramps

A Wrong Way sign is placed where a driver is heading the wrong way on a street or freeway ramp.

If you are looking at it, you are already traveling against the traffic. The right response is to stop and get off the road at once.

These signs warn and redirect drivers who are heading the wrong way on streets or freeway ramps

A One Way sign means you may only travel in the direction its arrow indicates.

On a one-way street there is nobody coming the other way, so the whole width is used in one direction. Entering against it meets all of it head-on.

These signs indicate you may only travel in the direction indicated by the sign’s arrow

A prohibited sign means you cannot do something, such as make a left turn.

The slash means the movement drawn under it is not allowed here. It is one of the few signs that needs no words at all.

These signs indicate you cannot do something, for example, no U-turn or no left turn

A no U-turn sign is one of the prohibited signs, and U-turns are not allowed where one is posted.

A U-turn crosses every lane of traffic at once and takes longer than any other movement. Where it is banned, the sightlines are not there for it.

These signs indicate you cannot do something, for example, no U-turn or no left turn

A prohibited sign showing a turn crossed out means that turn may not be made at this location.

The turn is banned because of something you cannot see from the stop line, such as a hidden crossing or a bus lane.

Prohibited signs: These signs indicate you cannot do something, for example, no U-turn or no left turn
