Right-of-way rules decide who goes first at intersections and merges. They never hand anyone the right-of-way automatically; you must read the situation and yield when it calls for it.

Know the rule

No one should assume they automatically have the right-of-way; the situation and circumstances at the intersection must always be considered.

Handbook p. 28 ↗

Yield the right-of-way to:

  • The driver who is at, or arrives before you at, the intersection
  • Drivers in the opposing lane when you are turning left
  • The driver on your right at an all-way stop if you both arrive at the same time
  • Drivers on a public highway when you enter from a driveway or private road
  • Drivers already on an interstate or limited-access highway when you're on the ramp
  • Pedestrians, bicyclists and other drivers still in the intersection

Know the rule

Only the first vehicle in a funeral procession must obey traffic signs and signals, and all vehicles in it must have headlights on. Don't cut into or interfere with a funeral procession.

Handbook p. 28 ↗

Traffic control devices

Traffic signals, signs, pavement markings, and directions given by law enforcement, highway personnel, and school crossing guards.

Handbook p. 28 ↗

Pedestrian hybrid beacon (PHB)

A signal for midblock or uncontrolled crossings: two red lenses above one yellow. It stays dark until a pedestrian pushes the button, then runs yellow to red to stop traffic.

Handbook p. 28 ↗

Know the rule

When a PHB is activated, its steady and flashing lights direct drivers to slow and stop while pedestrians get a WALK signal; once the pedestrian has crossed, the beacon goes dark again.

Put it into practice

You and another car arrive at a four-way stop at the same moment, and it's on your right. Yield and let it go first. If it had arrived before you, it would go first no matter which side it was on.

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.

At an all-way stop, if two drivers arrive at the same time, who should yield?
  1. Yield to the driver on your right
  2. The driver going straight goes first
  3. The driver turning left goes first
  4. Yield to the driver on your left

Answer: Yield to the driver on your right

You should yield to the driver on your right at an all-way stop if you both arrive at the same time.

  1. Vehicles waiting behind you
  2. Only pedestrians, not vehicles
  3. Only vehicles turning the same way
  4. Drivers in the opposing traffic lane

You must yield the right-of-way to drivers in the opposing lane when making a left turn.

  2. Whichever vehicle signals first
  3. The vehicle on the right
  4. The vehicle entering the highway

  2. Only the first vehicle in the procession
  3. Every vehicle in the procession individually
  4. Only the last vehicle

Answer: Only the first vehicle in the procession

Handbook p. 28 ↗
What should you never assume about right-of-way rules at an intersection?
  1. That other drivers may fail to yield
  2. That pedestrians in a crosswalk get priority
  3. That you automatically have the right-of-way
  4. That emergency vehicles get priority

Answer: That you automatically have the right-of-way

The handbook warns that no one should assume they automatically have the right-of-way; circumstances must always be considered.

Handbook p. 28 ↗

  1. At railroad grade crossings
