Roundabouts — Idaho Permit Test
Roundabouts on the Idaho permit test — 7 rules, each with the reason behind it and a question on it while it is fresh.
The rules
In a roundabout all drivers must yield the right-of-way to vehicles already in the circle.
Traffic already going round has nowhere to stop, so the driver waiting at the edge is the one who can.
In a roundabout intersection, all drivers must yield the right-of-way to vehicles that are already in the circle
A roundabout is a one-way circular intersection where you must always turn right to enter and to exit.
Every movement through it is a right turn, whichever way you are eventually going.
The roundabout is a one-way circular intersection where you must always turn right to enter and exit
Drivers must enter a roundabout counter-clockwise and merge into the circle, whether they are turning right, turning left, making a U-turn or going straight through.
There is no left turn across the middle, so a left turn becomes three quarters of a lap.
Drivers must enter the roundabout counter-clockwise and merge into the circle, whether they need to make a right turn, a left turn, a U-turn, or continue forward straight through the intersection
At a roundabout, yield to traffic on your left that is already in the roundabout.
Traffic goes round to the left of the entry, so that is the direction the gap has to come from.
Yield to traffic on your left already in the roundabout
Yield to pedestrians and bicyclists when entering and exiting a roundabout.
The crossings sit at the entry and the exit, which are the two moments a driver is watching the circle instead.

As you approach your exit from a roundabout, turn your right turn signal on.
The signal tells the driver waiting to enter that the gap they need is about to appear.
As you approach your exit, turn your right turn signal on
Slow down and keep your speed low in a roundabout, and obey all traffic signs and pavement markings.
A roundabout works because everyone in it is going slowly enough to stop for the car that did not see them.
Keep your speed low
On the test
Who has the right-of-way at an Idaho roundabout?
Vehicles already in the circle. Traffic already going round has nowhere to stop, so the driver waiting at the edge is the one who can. July 2026 Idaho Driver's Handbook, p.62: “In a roundabout intersection, all drivers must yield the right-of-way to vehicles that are already in the circle”
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.
What it costs
- One payment, once — not a subscription. Nothing renews and there is nothing to cancel, for an exam you sit one time.
- Free to start: a 10-question test and the first section of cards. No sign-up and no account.
- Paying opens the rest of the cards, unlimited full-length practice tests, and retests built from exactly the questions you got wrong.
- Every level up to Prepared — 3 tests passed in a row.
- Do the work, fail the real exam, and we refund you.
