What is the proper action when approaching a roundabout?

When approaching a roundabout, the proper action is to yield to traffic already in the roundabout. This is essential to ensure a smooth flow of traffic. Vehicles inside the roundabout have the right of way, and yielding helps prevent potential collisions and keeps the traffic moving efficiently.

This means that as you approach the roundabout, you should adjust your speed and be prepared to stop in order to let vehicles that are already circulating through it pass before you enter. This yielding rule applies to all road users, including cars and bicycles, making it a critical aspect of roundabout safety and functionality. By giving priority to those already in the roundabout, you contribute to minimizing delays and improving overall road safety.
