Right-of-way rules decide who goes first where signs or signals don't. The law says who must yield, but it never gives anyone the right-of-way, even on a green light. You're always responsible for avoiding a crash.

Know the rule

Yield to pedestrians, bicyclists and other drivers already in an intersection you're approaching.

Handbook p. 14 ↗

Know the rule

Always yield to pedestrians; they have the right-of-way at all intersections and crosswalks. Come to a complete stop and let them pass safely.

Handbook p. 14 ↗

Know the rule

Don't assume pedestrians can see or hear you or crossing signals; some are deaf, hard of hearing, deaf-blind or blind. A white cane or guide dog often identifies blind people.

Handbook p. 14 ↗

Know the rule

Bicycles are vehicles. Yield to bicyclists in a designated bike lane when merging with or crossing it to turn. Bicyclists on a sidewalk or crosswalk have a pedestrian's rights.

Handbook p. 14 ↗

Intersection right-of-way

Intersection right-of-way
SituationWho goes first
Four-way stopThe vehicle that got there first
Four-way stop, arrive togetherVehicle on the right; left one yields
Uncontrolled, arrive togetherVehicle on the right; left one yields
Turning leftOncoming traffic, unless green arrow/first at 4-way
Handbook p. 14 ↗

Uncontrolled intersection

An intersection without control devices such as stop signs or traffic lights.

Handbook p. 14 ↗

Know the rule

Before turning left, yield to pedestrians in the crosswalk and oncoming bicyclists and motorcyclists, taking time to judge their speed and distance.

Handbook p. 14 ↗

Other yield rules:

  • Changing lanes or passing: yield to vehicles already in that lane
  • Merging: yield to all vehicles on the road you're joining
  • Don't change lanes or merge if another vehicle must slow for you
  • Reversing: yield to all vehicles close enough to be a hazard
Handbook p. 14 ↗

Know the rule

On a steep, narrow road too tight for two vehicles, the vehicle going downhill yields by backing to a wider place or stopping, unless it's more practical for the uphill vehicle to back to a turnout.

Handbook p. 14 ↗

Put it into practice

You and another car reach a four-way stop at the same moment; it's on your right. You're the vehicle on the left, so you yield and let it go first.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

According to Colorado law, who must you always yield the right-of-way to?
  1. Pedestrians
  2. Only vehicles with a green light
  3. Only bicyclists in a bike lane
  4. Only emergency vehicles

Answer: Pedestrians

You must always yield the right-of-way to pedestrians when driving.

Handbook p. 14 ↗
At a four-way stop, if two vehicles arrive at the same time, who must yield?
  1. The vehicle on the right yields to the left
  2. Neither vehicle needs to yield
  3. The vehicle on the left yields
  4. Whichever vehicle is larger has the right-of-way

Answer: The vehicle on the left yields

When vehicles arrive simultaneously at a 4-way stop, the vehicle on the left must yield to the vehicle on the right.

Handbook p. 14 ↗
At an uncontrolled intersection with no signs or signals, who has the right-of-way if two vehicles arrive at the same time?
  1. The larger vehicle
  2. The vehicle on the right
  3. The faster vehicle
  4. The vehicle on the left

Answer: The vehicle on the right

At an uncontrolled intersection, the vehicle on the left must yield to the vehicle on the right.

Handbook p. 14 ↗
Before turning left, you must yield to oncoming traffic UNLESS which condition applies?
  1. You have a green arrow or arrived first
  2. Your turn signal has been on for over 5 seconds
  3. You are driving a larger vehicle
  4. There is no crosswalk present

Answer: You have a green arrow or arrived first

You must yield to oncoming traffic when turning left, unless you have a green arrow or arrived first at a four-way stop.

Handbook p. 14 ↗
On a narrow mountain road where two vehicles meet and cannot pass, who generally must yield?
  1. The vehicle going uphill
  2. Whichever vehicle is smaller
  3. The vehicle going downhill
  4. The vehicle that arrived second

Answer: The vehicle going downhill

The vehicle going downhill must yield, usually by backing up, except where it's more practical for the uphill vehicle to yield instead.

Handbook p. 14 ↗
You are turning left and have a green arrow. Do you still need to yield to oncoming traffic before completing the turn?
  1. Yes, unless you arrived at the light first
  2. Only if oncoming traffic has a red light
  3. No, a green arrow is the exception to that rule
  4. Yes, you must always yield regardless of the arrow

Answer: No, a green arrow is the exception to that rule

The handbook notes you must yield to oncoming traffic when turning left, unless you have a green arrow or arrived first at a four-way stop.
