Colorado Road Signs Cheat Sheet.
The night-before summary, built like the exam.

The Numbers to Remember

Colorado doesn't publish a fixed question count or a passing-score percentage for this test, so there's no magic number to memorize here — the one thing officially confirmed is the scope of what's tested. Don't let the absence of a published number fool you into thinking the test is loosely defined; it just means the handbook itself is the boundary.

• The handbook states the test questions cover road signs, driving under the influence, driving rules, safety rules, and legal items — treat all five as equally fair game.
• No published item count means you can't guess your way past a weak category by hoping it's underrepresented on the actual test.
• No published passing score means the safe target is mastery across every named category, not a minimum squeak-by percentage.
• Because the categories are named explicitly, resist the urge to over-study signs while skimming DUI, safety, and legal-item material.

Sign Shapes at a Glance

• Octagon, red — stop; this shape is used for nothing else on the road.
• Downward triangle — yield; slow and give way.
• Diamond, yellow — general warning about upcoming hazards or road conditions.
• Pentagon, yellow — school zone or school crossing ahead.
• Round — railroad crossing warning.
• Rectangle, white — regulatory rule such as speed limits or turn restrictions.
• Orange — construction or work-zone warning; slow down.
• Green — guide/directional information like exits and distances.
• Blue — motorist services such as gas, food, or hospitals.
• Brown — recreational or scenic-area guidance.

Right-of-Way in One Breath

First to stop at an all-way intersection goes first. Pedestrians in a crosswalk — marked or unmarked — beat turning or crossing cars. Emergency vehicles running lights and sirens beat everyone else on the road; pull right and stop until they pass. Merging traffic yields to the lane it's entering rather than forcing its way in. Traffic already circulating inside a roundabout beats traffic waiting to enter it. When a scenario names more than one of these at once, work through them in that order rather than guessing.

Top Traps

• Assuming DUI and legal-item questions are rare. The handbook names them as tested categories exactly like signs — don't skip them while cramming shapes.
• Treating the posted speed limit as always safe. The basic speed rule requires slowing below it in rain, fog, or construction — the test often rewards judgment over the printed number.
• Confusing yield and stop shapes under pressure. An octagon always means stop; a downward triangle always means yield — don't let color alone decide your answer.
• Forgetting pedestrians at unmarked crosswalks. The absence of painted lines doesn't remove a pedestrian's right-of-way.
• Underestimating fatigue as a real impairment category. Drowsy driving is tested alongside alcohol and drug impairment because both slow reaction time similarly.
• Skipping a timed practice run the night before. A single untimed read-through of the handbook doesn't reveal which categories are actually shaky under real test conditions.
