Roundabout tips — Hawaii Permit Test
Roundabout tips on the Hawaii permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A roundabout is a one-way circular intersection where entering traffic must yield the right-of-way to traffic already circulating.
If cars coming in did not yield, they would cut into the circle and hit cars already going around.
A roundabout is a one-way circular intersection in which entering traffic must yield the right-of-way to circulating traffic.
In a roundabout, drive to the right of the central island and go counterclockwise.
A car going the wrong way around the island meets every other car head-on.
Drive to the right of the central island and proceed in a counterclockwise direction.
Entering a roundabout, look to the left for traffic and yield to traffic, including bicyclists, already in it.
Traffic in the circle comes at you from the left, so looking right shows you nothing.
Look to the left for traffic and yield to traffic, including bicyclists, already in the roundabout.
Yield to pedestrians and bicyclists both as you enter and as you exit a roundabout.
People cross at the exits too, and a driver speeding out of the circle may not see them.
Yield to pedestrians and bicyclists as you enter and exit the roundabout.
Use your right turn signal to exit a roundabout.
Drivers waiting to enter cannot tell whether you are leaving or staying in the circle unless you signal.
Use your right turn signal to exit the roundabout.
If you miss your exit in a roundabout, drive around again until you reach it.
Stopping or backing up inside the circle invites the car behind you to hit you.
If you miss your exit, drive through the roundabout again until you reach your exit.
On the test
At a roundabout, who must yield the right-of-way?
Traffic entering the roundabout. If cars coming in did not yield, they would cut into the circle and hit cars already going around. State of Hawaii Driver’s Manual, p.65: “A roundabout is a one-way circular intersection in which entering traffic must yield the right-of-way to circulating traffic.”
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.
