What must you do when approaching a roundabout?

When approaching a roundabout, the proper action is to yield to traffic that is already in the roundabout. This is essential for maintaining safety and smooth traffic flow. Vehicles in the roundabout generally have the right-of-way, and yielding to them helps prevent collisions and allows for an orderly entry into the roundabout.

It’s also important to understand that yielding is part of the design of roundabouts, as it is meant to minimize stop-and-go traffic, allowing for continuous movement when possible. The roundabout's circular flow prevents the need for stop signs or traffic lights, enhancing efficiency and reducing the likelihood of accidents.

Approaching without stopping, speeding up to merge, or honking the horn are not appropriate actions when navigating a roundabout and can lead to dangerous situations and confusion among drivers. Proper yielding ensures safety for all road users entering or circulating within the roundabout.
