Minnesota Blue Card Practice Test

When you exit a roundabout, you should use your:

1. Brake lights

2. Horns

3. Turn signal

4. Reverse lights

The correct answer is: Turn signal

Using your turn signal when exiting a roundabout is essential for safe driving practices. The primary purpose of a turn signal is to communicate your intentions to other drivers and pedestrians around you. When you signal to exit the roundabout, you indicate that you are leaving the circular traffic flow, which helps inform others of your movement and maintains safe distance among vehicles. The lack of signaling can lead to confusion among other drivers, as they may not be aware of your intentions and may misjudge the space available to them. Therefore, using a turn signal when exiting a roundabout is a critical element of defensive driving, contributing to overall road safety. While braking lights signal that you are slowing down or stopping, they do not convey your intention to change lanes or directions like a turn signal does. Similarly, horns are typically reserved for alerting other drivers to immediate danger, and reverse lights indicate that a vehicle is backing up, which is not relevant when exiting a roundabout.
