North Carolina DMV Practice Test

When approaching a roundabout, the appropriate action is to yield to traffic that is already circulating within the roundabout. This means that you must give way to vehicles that are in the roundabout before entering. This procedure helps maintain a smooth flow of traffic and enhances safety by reducing the likelihood of collisions.

By yielding, you ensure that vehicles already traveling in the roundabout can continue without interruption, which is essential in maintaining the circular traffic flow that roundabouts are designed to facilitate. It’s important to be aware of your surroundings and adjust your speed accordingly to wait for a safe gap in traffic before entering.

The other actions listed would undermine the function of a roundabout and compromise safety on the road. Entering at any time without yielding could lead to collisions, speeding up to clear the roundabout quickly can increase the risk of accidents, and although signaling when exiting is important, the primary rule when approaching is to yield to existing traffic.
