If you are going straight through a roundabout, when should you signal?

Answer: B — Only when passing the exit before the one you want

When approaching a roundabout and going straight through, the appropriate time to signal is indeed as you pass the exit before the one you intend to take. This practice informs other road users of your intention to exit, aiding in smoother traffic flow and enhancing safety. By signaling only after leaving the previous exit, you indicate your ongoing direction while effectively communicating with drivers around you. It is crucial to ensure that other vehicles yield to you correctly, especially in busy roundabouts where multiple vehicles may be navigating simultaneously. Other choices indicate either premature signaling, which can confuse other drivers, or suggest that signaling is unnecessary altogether, which does not promote clear communication on the road. Understanding your signaling helps maintain safe interactions among all road users, particularly in complex traffic situations like roundabouts.
