What should you do if you approach a roundabout?

When approaching a roundabout, it is essential to yield to traffic already inside the roundabout. This rule is in place to ensure safe and smooth traffic flow. Vehicles within the roundabout have the right of way, which prevents potential collisions and minimizes confusion among drivers.

Yielding allows drivers to make informed decisions about entering the roundabout without disrupting the flow of traffic that is already moving. Additionally, being aware of the traffic patterns in the roundabout can help in better anticipating the actions of other drivers, thereby enhancing overall road safety.

Other actions like speeding up to enter quickly, turning on hazard lights, or stopping completely are all inappropriate in this context. Speeding may lead to dangerous situations, using hazard lights can confuse other drivers, and coming to a complete stop unnecessarily can disrupt traffic and create hazards. Therefore, yielding is the appropriate and safest action to take when approaching a roundabout.
