How should you handle a roundabout when approaching from the left?

When approaching a roundabout from the left, the appropriate action is to yield to vehicles already on the roundabout. This is crucial for maintaining a safe flow of traffic. Roundabouts are designed to facilitate continuous movement, and vehicles inside the roundabout have the right of way. Yielding allows you to assess gaps in traffic and enter the roundabout safely without disrupting the flow or risking collisions.

While there are other actions related to roundabouts—such as signaling and merging—yielding is the primary responsibility of drivers approaching a roundabout to ensure safety for all road users. The other options, such as accelerating immediately or ignoring other vehicles, would create hazardous situations and are not in accordance with safe driving practices.
