Colorado Road Sign Practice Test

How road signs are tested in Colorado

Road sign questions are part of the Colorado written knowledge test (25 multiple-choice questions, 20 right to pass). Know the signs well and those questions become easy points.

Signs from the Colorado Driver Handbook (DR 2337 (12/05/24)). What every kind of sign means, by shape and color: our road sign guide.

Signs the Colorado Driver Handbook adds

• Traffic Signs

  A merge sign means traffic from another road will enter; be prepared for vehicles moving into your lane. p. 8

• Passing

  It is illegal to exceed the posted speed limit while passing, to pass in a marked no-passing zone, or to pass a school bus with red lights flashing and its stop arm out. p. 16

• Hills and Curves

  Always slow down before a curve: too fast and your tires can't grip, so the vehicle skids; start accelerating only after the middle of the curve. p. 16

• Animals

  Watch for animals, especially in rural and mountain areas and between dusk and dawn, when about 90% of deer and elk crashes happen; in a marked animal crossing, first slow down and look for animals. p. 26

• Traffic Signals

  At a steady red light, stop until it turns green; after stopping and yielding to pedestrians and traffic, you may turn right on red unless a sign prohibits it. p. 7

• Traffic Signs

  Speed limit signs can show the maximum or the minimum speed allowed. p. 7

• Reduced speed zones

  Signs show when a reduced speed limit is in effect; and whatever the posted limit, you may need to slow down further to keep yourself and others safe. p. 12

• Traffic Signs

  Blue signs mean: motorist services. p. 8

• Traffic Signs

  Brown signs mean: recreation and cultural places. p. 8

• Disabled parking signs

  Disabled parking spaces are only for vehicles displaying a disabled parking permit; the crosshatched area beside them is for van access, and parking there is never allowed. p. 9

• Route signs and markers

  Route signs' shapes show the type of road: Interstate, U.S., State or County highway. p. 9

• Pass 3 ft min signs

  PASS 3 FT MIN signs (black on white) remind drivers to leave at least 3 feet when passing a bicyclist, a rule that applies on every road even where no sign is posted. p. 9

• Bicycle and pedestrian crossing signs

  Bicycle and pedestrian crossing signs (black symbols on yellow) are used where both bicyclists and pedestrians may cross, such as where a shared use path meets the road. p. 9

• Quiet Zone signs

  Crossings in quiet zones have a No Train Horn sign below the advance warning sign; train horns don't sound there, so the flashing lights and gates are your warning. p. 21

• Crossbuck signs

  Treat a crossbuck like a yield sign; a sign below it shows the number of tracks if there's more than one; crossbucks are normally caution signs but become regulatory when a train approaches. p. 21
