Roundabouts — South Carolina Permit Test
Roundabouts on the South Carolina permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Traffic in a roundabout or traffic circle travels counterclockwise around the center island.
Entering the wrong way puts you head-on into circulating traffic.
Enter a roundabout or traffic circle in a counterclockwise direction.
Traffic entering a roundabout yields the right-of-way to traffic already circulating in it.
If entering cars pushed in, the circle would jam and cars inside would be struck from the side.
Vehicles travel counterclockwise around a raised center island with entering traffic yielding the right-of-way to circulating traffic.
Leaving a roundabout, proceed to the appropriate exit, signal your intent, and exit.
Drivers waiting to enter cannot tell whether you are leaving or continuing round unless you signal.
Proceed to the appropriate exit, signal intent, and exit.
Roundabouts are safer than traditional intersections because they eliminate head-on and high-speed right-angle collisions.
Those two crash types cause the most serious injuries at ordinary crossings.
Roundabouts are safer than traditional intersections because they eliminate head-on and high-speed right angle collisions.
On the test
Which way do you travel in a roundabout?
Counterclockwise around the island. Entering the wrong way puts you head-on into circulating traffic. South Carolina Driver's Manual, p.82: “Enter a roundabout or traffic circle in a counterclockwise direction.”
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.
