What should drivers remember to do when approaching a roundabout?

When approaching a roundabout, drivers should remember to yield to vehicles that are already in the roundabout. This is a fundamental rule of roundabout navigation that helps maintain a smooth flow of traffic and reduces the risk of collisions. By yielding to the traffic that has the right of way, drivers can safely merge into the circulating lane.

Other actions, such as stopping or speeding up to enter quickly, are not appropriate in this context. Stopping before entering the roundabout is unnecessary when the way is clear, and doing so could disrupt the flow of traffic. Similarly, speeding up to enter the roundabout can increase the risk of an accident, as it may not allow enough time to assess the movements of vehicles within the roundabout. The key focus in roundabout etiquette is to yield adequately and enter the roundabout when it is safe to do so.
