Illinois Driving Permit Practice Test

What should you do if you approach a roundabout?

1. Accelerate through the roundabout

2. Yield to traffic in the roundabout and enter when safe

3. Stop before entering

4. Maintain speed and weave through traffic

The correct answer is: Yield to traffic in the roundabout and enter when safe

When approaching a roundabout, it's crucial to yield to traffic that is already in the roundabout. This ensures a smooth flow and safety for all vehicles involved. Roundabouts are designed to facilitate continuous traffic flow and minimize the need for full stops, hence yielding allows you to assess the situation and enter the roundabout when there is a safe gap in traffic. This practice reduces the likelihood of accidents and promotes efficiency in managing traffic. While accelerating through the roundabout may seem tempting, it could lead to collisions, as other drivers might be unaware of your approach. Stopping before entering the roundabout is also unnecessary unless directed by signs or signals; the aim is to maintain traffic movement. Furthermore, maintaining speed and weaving through traffic does not align with the necessary caution required in navigating roundabouts and can create dangerous situations. Therefore, yielding to oncoming traffic and ensuring it's safe to enter is the preferred and safest action.
