Right-of-Way and Intersections: Avoid the Most Common DMV Test Mistakes

Right-of-Way and Intersections: Avoid the Most Common DMV Test Mistakes

Why Right-of-Way Questions Trip People Up

Right-of-way is one of the most misunderstood topics on the California DMV written knowledge test. It’s not about being polite—it’s about following clear rules that keep traffic moving safely. The test loves to ask about intersections, roundabouts, pedestrians, and mountain roads because these are situations where small mistakes cause big problems. In this guide, we’ll walk through each area, point out the common traps, and show you how the test phrases these questions.

Controlled Intersections: Signs and Signals

A controlled intersection has traffic lights, stop signs, or yield signs. The rule is simple: obey the sign or signal. But the test often adds a twist: even with a green light, you must yield to pedestrians and to vehicles already in the intersection. For example, if you’re turning left on a green arrow, you have the right-of-way—but only after yielding to pedestrians in the crosswalk.

Common mistake: Assuming a green light means “go no matter what.” The correct answer is always “proceed with caution” and yield to anyone already in the intersection.

Worked scenario: You’re at a four-way stop. You arrive first, then a car from the left, then a car from the right. Who goes first? You do, because you arrived first. If you all arrive at the same time, yield to the vehicle on your right.

Uncontrolled Intersections: No Signs, No Signals

An uncontrolled intersection has no traffic lights, stop signs, or yield signs. The rule here is: the first vehicle to arrive has the right-of-way. If two vehicles arrive at the same time, the vehicle on the right goes first. If a pedestrian is crossing, they always have the right-of-way.

Common mistake: Thinking that the bigger road always has the right-of-way. In an uncontrolled intersection, arrival time is what matters, not the size of the road.

Worked scenario: You and another car arrive at an uncontrolled intersection at the same moment. The other car is on your left. You should go first because you are on the right. The test might phrase it as: “Two vehicles arrive at an uncontrolled intersection at the same time. Who has the right-of-way?” The answer is the vehicle on the right.

Roundabouts: Keep Moving and Yield

Roundabouts confuse many drivers. The key rules: slow down as you approach, yield to traffic already in the roundabout, and enter to the right when there’s a safe gap. Travel counter-clockwise. Don’t stop or pass inside the roundabout. Signal when you change lanes or exit. If you miss your exit, continue around.

Common mistake: Stopping inside the roundabout to yield to entering traffic. That’s dangerous and wrong—you have the right-of-way once you’re in.

Worked scenario: You’re approaching a roundabout and see a car coming from your left, already circulating. You must yield and wait for a gap. The test might ask: “When entering a roundabout, you should yield to: A) Traffic on your left B) Traffic already in the roundabout C) Traffic on your right.” The correct answer is B.

Pedestrians and Crosswalks: Always Yield

Pedestrians have the right-of-way at crosswalks, whether marked or unmarked. When turning, you must yield to pedestrians in the crosswalk. Even if you have a green light, you must wait for pedestrians to clear your path.

Common mistake: Thinking that a green light gives you the absolute right-of-way. The test often includes: “You are turning right at a green light. A pedestrian is crossing in the crosswalk. You should: A) Proceed with caution B) Yield to the pedestrian C) Honk to warn them.” The answer is B.

Worked scenario: You’re making a left turn at an intersection with a green light. A pedestrian is crossing the street you’re turning into. You must wait for them to cross before completing your turn.

Mountain Roads: Narrow and Steep

On mountain roads, the rules adjust for safety. If you’re driving uphill, you generally have the right-of-way over downhill traffic because it’s harder for you to start again if you stop. However, if the downhill vehicle is a large truck or bus, yield to them. Also, if you’re driving a large vehicle, you should yield to smaller vehicles.

Common mistake: Assuming the uphill vehicle always has the right-of-way. The test might ask: “You are driving uphill on a narrow mountain road. A large truck is coming downhill. Who has the right-of-way?” The answer is the truck, because it’s harder for them to stop and start.

Worked scenario: You’re going uphill on a narrow road and meet a smaller car coming downhill. You have the right-of-way, but you should still be prepared to yield if the other driver doesn’t follow the rule. Safety first.

Quick Self-Check

Test your understanding with these three questions.

1. Two vehicles arrive at an uncontrolled intersection at the same time. Who goes first? A) The vehicle on the left B) The vehicle on the right C) The larger vehicle

2. You are entering a roundabout. You should yield to: A) Traffic on your left B) Traffic already in the roundabout C) Traffic on your right

3. You are turning right at a green light. A pedestrian is in the crosswalk. You should: A) Proceed with caution B) Yield to the pedestrian C) Honk to warn them

Answers: 1-B, 2-B, 3-B.

Key Takeaways

  • At intersections, yield to pedestrians, then to vehicles already in the intersection.
  • When two vehicles arrive at the same time, the vehicle on the right goes first.
  • In a roundabout, yield to traffic already circulating; don’t stop inside.
  • Pedestrians have the right-of-way at crosswalks, even when you have a green light.
  • On mountain roads, yield to downhill traffic if you’re going uphill, especially to large trucks.
