Tennessee Permit Practice Test

What should you do when approaching a roundabout?

1. Yield to vehicles already in the roundabout

2. Enter without slowing down

3. Stop and wait for a signal

4. Use your horn to alert others

The correct answer is: Yield to vehicles already in the roundabout

When approaching a roundabout, yielding to vehicles that are already inside the roundabout is crucial for maintaining a smooth flow of traffic and ensuring the safety of all drivers and pedestrians. Vehicles already in the roundabout have the right of way, which means that those entering must wait for a safe gap to merge into the circulating traffic. This practice helps to prevent collisions and keeps the roundabout functioning efficiently. Entering without slowing down can lead to dangerous situations as it may cause conflicts with vehicles already in the roundabout. Stopping and waiting for a signal is unnecessary, since roundabouts operate on a give-way system rather than traffic lights. Using your horn to alert others might create confusion and is not an effective way to communicate in this scenario, as all drivers are expected to be aware of their surroundings. By yielding to existing traffic, drivers contribute to safer road conditions and a better driving environment for everyone.
