When there are no traffic control devices at an intersection, who has the right of way?

• A. The vehicle on the left has priority, regardless of arrival time.
• B. No one has priority; proceed when safe.
• C. Yield to vehicles already in the intersection if they arrived first.
• D. The vehicle on the right has right of way if you reach the intersection at the same time; otherwise follow the rule of first to arrive.

Answer: (D)

At an intersection without traffic control devices, right-of-way is determined by who arrives first, and if you arrive at the same time, the driver on your right goes first. This combines two practical rules: first to arrive goes first, and if arrival is simultaneous, yield to the vehicle on your right. This is the safest way to gauge priority when there are no signals or signs.

So the best answer reflects both parts: proceed if the other driver is not on your right and you’ve arrived first; if you both arrive together, yield to the vehicle on your right. The other options misstate the priority, either giving automatic precedence to the left, claiming there’s no priority at all, or using an imprecise rule about vehicles already in the intersection.

Remember to move carefully, signal, make eye contact, and yield to pedestrians as needed.
