Roundabout entry and yielding — Arizona Permit Test
Roundabout entry and yielding on the Arizona permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Vehicles approaching a roundabout must yield to all vehicles already in the roundabout, and to large vehicles entering at the same time.
Traffic inside is already moving and has nowhere to go. Pulling in front of it causes a side crash.
Vehicles approaching the roundabout must yield to all vehicles already in the roundabout and must yield to large vehicles that are entering the roundabout at the same time.
Always enter a roundabout to the right of the central island.
Traffic in a roundabout flows one way. Going left of the island puts you head-on with it.
Always enter a roundabout to the right of the central island.
Roundabouts are designed for speeds of 15-20 mph, so slow down as you approach.
Come in too fast and you cannot yield or take the curve around the island.
Slow down as you approach the intersection; roundabouts are designed for speeds of 15-20 mph.
Always yield to pedestrians and bicyclists crossing the road at a roundabout.
People on foot or on a bike have no steel around them. A car that does not stop hurts them badly.
Always yield to pedestrians and bicyclists that are crossing the road.
Enter a roundabout when there is a gap in traffic.

Enter the roundabout when there is a gap in traffic.
On the test
Who must yield when entering a roundabout?
Cars entering yield to cars already inside. Traffic inside is already moving and has nowhere to go. Pulling in front of it causes a side crash. Arizona Driver License Manual and Customer Service Guide, p.28: “Vehicles approaching the roundabout must yield to all vehicles already in the roundabout and must yield to large vehicles that are entering the roundabout at the same time.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
