Colorado Driver Handbook
科州驾驶手册中英文对照

Applicants must meet identity, residency, vision, and testing requirements. Permit holders must follow age and supervised-driving rules; minor drivers are subject to graduated licensing.

• Carry a valid license or permit when driving.
• Update your address as required by the DMV.
• Passenger and nighttime limits may apply to minor drivers.

Sign shape and color reveal purpose: an octagon means stop, an inverted triangle means yield, a circle usually warns of a railroad crossing, and diamonds generally warn of hazards.

• Yellow lines separate opposing traffic; white lines separate same-direction traffic.
• Broken lines permit crossing when safe; solid lines generally restrict it.
• Obey orange work-zone signs and flaggers.

A green light never removes the duty to look. Before proceeding or turning, confirm the intersection is clear and yield to vehicles, bicyclists, and pedestrians with lawful priority.

• Flashing red means stop; flashing yellow means slow and proceed cautiously.
• Right on red requires a complete stop and no prohibiting sign.
• Yield to traffic already circulating in a roundabout.

The posted limit is the maximum legal speed under good conditions; slow further for weather, visibility, or traffic. Keep at least a three-second following interval in normal conditions.

• Signal, check mirrors, and look over your shoulder before changing lanes.
• Avoid lingering beside another vehicle.
• Give motorcycles a full lane and adequate following space.

Use the acceleration lane to approach freeway speed, merge into a safe gap, and yield to freeway traffic. If you miss an exit, continue to the next one—never back up.

• Keep right except when passing and return safely afterward.
• Large trucks have larger blind spots, longer stopping distances, and wider turns.
• Never squeeze to the right of a truck making a right turn.

Rain, snow, ice, fog, and mountain roads reduce traction and visibility. Slow down, add following distance, make smooth inputs, and keep lights and tires in good condition.

• Use low beams in fog and dim high beams for approaching traffic.
• If hydroplaning, ease off the accelerator and avoid hard braking or steering.
• Use a lower gear on long downgrades to reduce brake overheating.

Drivers must yield to pedestrians in crosswalks and at intersections, with special care for children, older adults, and people using a white cane or guide dog.

• Give bicyclists and e-bike riders at least three feet when passing.
• Without a physical median, a school bus displaying red lights generally requires both directions to stop.
• Check sidewalks, bike lanes, and blind spots before turning.

Alcohol, cannabis, prescription medicine, and other drugs can impair reaction, judgment, and coordination. A regular driver may be DUI at 0.08% BAC, while lower levels can still be unlawful.

• Do not read or send messages while driving.
• Fatigue reduces attention and reaction time.
• Arrange a sober driver or another way home in advance.

When an emergency vehicle approaches from behind, pull safely to the right and stop. Near a stopped roadside vehicle displaying warning lights, move over when safe or slow as required.

• During a blowout, hold the wheel firmly and ease off the accelerator.
• After a crash, stop, assist injured people, exchange information, and report as required.
• If safely operable, move vehicles out of traffic to reduce secondary crashes.

Check traffic and signal before parking, then set the parking brake. Point wheels toward the curb downhill and away from the curb uphill.

• Do not block traffic, driveways, fire hydrants, or accessible spaces.
• Turn off the engine and take the keys before leaving.
• Every occupant should use the restraint appropriate for age and size.
