What action should you take before entering a roundabout?

Slow down
Move quickly
Use your turn signal
Blow your horn

The correct answer is: Slow down

When entering a roundabout, it's important to take the necessary precautions in order to safely navigate through it. This includes slowing down to assess the traffic flow, as speed and maneuvering within a roundabout can be challenging. Moving quickly or not reducing your speed can lead to accidents. Using your turn signal is also important to indicate your intended direction and allow other drivers to adjust their speed accordingly. Blowing your horn is not necessary and can startle other drivers, causing confusion and potential hazards.
