Right-of-Way and Intersections: What the DMV Test Really Asks
Right-of-way and intersections: the rules people get wrong
Right-of-way questions are some of the easiest points on the California DMV written knowledge test, and also the most commonly missed. The rules themselves are short. The trouble is that real life is messy, and test questions are written to see whether you know the rule, not just the habit.
Start with the core rule and everything else follows: yield to pedestrians first, then to vehicles already in the intersection. When two vehicles arrive at the same time and neither is already in the intersection, the vehicle on the right goes first.
One thing to know up front: having the right-of-way is not permission to ignore a hazard. On the test, the safe answer is almost always the one where you give up your right-of-way to prevent a collision.
Controlled and uncontrolled intersections
What the test is asking
A controlled intersection has signs or signal lights telling you what to do. An uncontrolled intersection has none. You have to read the situation yourself.
At a controlled intersection:
- Obey the signal or sign in front of you.
- If it's a four-way stop and you got there first, you go first.
- If you arrive at the same time, yield to the vehicle on your right.
- If you're turning left, yield to oncoming traffic going straight or turning right.
At an uncontrolled intersection, the same arrival-order and yield-to-the-right ideas apply, but nothing tells you to stop. You approach slowly, look left, right, and ahead, and be ready to stop.
A worked scenario
You pull up to an uncontrolled intersection at the same moment as a car on your right. The test phrasing usually looks like: "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. If the other car is on your left, you go first. If you both arrive and you can't tell who was first, treat it as a tie and yield to the right.
The mistake
People assume a stop sign always means I stop, then I go. It doesn't. At a four-way stop, first-arrival order matters, and a tie goes to the right.
Roundabouts
What the test is asking
Roundabout questions usually test direction and yielding, not speed. Traffic goes counter-clockwise around a central island, and you yield to traffic already in the roundabout before you enter. Signal when you change lanes or exit. If you miss your exit, go around again.
A worked scenario
A question shows a roundabout with a car already circling toward your entry point. You're approaching in the right-hand lane. Do you enter and assume they'll slow down? No. You wait for a big enough gap, enter to the right, and merge. If the roundabout has multiple lanes, choose your entry and exit lane based on where you're going.
The mistake
Treating a roundabout like a four-way stop. There's no "first arrival" rule here, only yielding to traffic already circulating.
Pedestrians and crosswalks
What the test is asking
Pedestrians come first. When you turn at an intersection, you still yield to people in the crosswalk. A green light is not a promise that the crosswalk is clear.
A worked scenario
You have a green left-turn arrow, and a pedestrian steps into the crosswalk you're about to cross. The test wants: wait for the pedestrian. Same answer if you're turning right on red, or turning at a controlled intersection with a walk signal showing. The pedestrian has the right-of-way.
The mistake
Thinking a green light or turn arrow overrides the crosswalk. It doesn't.
Mountain roads
What the test is asking
On a narrow mountain road, who backs up or yields? The usual test framing is that the downhill vehicle yields to the uphill vehicle, because starting again uphill is harder, and the vehicle going downhill has an easier time backing. If you're the downhill driver, pull over or back up as needed. Also watch for posted signs on blind curves and narrow stretches.
A worked scenario
A question describes two vehicles meeting on a one-lane mountain road, one going up and one coming down. The expected answer is that the downhill vehicle yields, not the one climbing.
The mistake
Applying city habits, like whoever is moving faster goes first, or thinking the uphill car should back down.
Answering these questions under pressure
Before you pick an answer, run a short check in your head: what's controlling this spot (signal, sign, or nothing), who else is there (pedestrians, bikes, oncoming cars), and what does the rule say. If two answers are both safe, choose the one that yields to the most vulnerable road user. If two answers both sound correct, choose the one that prevents a collision.
Self-check
-
Two cars reach an uncontrolled intersection at the same moment, one from your left and one from your right. You are facing the car on your right. Who goes first? A. You do, because you were moving. B. The car on your right. C. Whichever car is larger.
-
You're entering a roundabout. A car is already circulating toward your entry. What do you do? A. Enter, because you have the right-of-way. B. Stop completely and wait for the roundabout to empty. C. Yield and enter only when there's a safe gap.
-
You're going downhill on a narrow mountain road and meet a vehicle coming uphill. Who yields? A. The uphill vehicle backs up. B. The downhill vehicle yields. C. Neither; you both squeeze past.
Answers: 1. B. 2. C. 3. B.
Key takeaways
- Pedestrians come first, then vehicles already in the intersection.
- A first-arrival tie goes to the vehicle on the right.
- In a roundabout you yield to traffic already circulating; there is no first-arrival rule there.
- Green lights and turn arrows don't cancel the crosswalk.
- On mountain roads, the downhill vehicle is the one expected to yield.

Frequently asked questions
Who has the right-of-way at an uncontrolled intersection?
The vehicle that arrives first goes first. If two vehicles arrive at the same time, yield to the vehicle on your right.
Do I have to yield to pedestrians when I have a green light?
Yes. Pedestrians in a crosswalk have the right-of-way, even when you have a green light or a turn arrow.
Who yields on a narrow mountain road?
The downhill vehicle is expected to yield to the uphill vehicle, since restarting uphill is harder and backing downhill is easier.
What do I do if I miss my exit in a roundabout?
Continue around the roundabout and come back to your exit on the next lap.
