Which of the following actions should cyclists take to enhance their safety?

Wearing helmets is a crucial safety measure for cyclists, as they provide significant protection against head injuries in the event of a fall or collision. Helmets are designed to absorb impact energy and reduce the risk of serious head trauma, which can occur even during minor accidents.

Cyclists who wear helmets demonstrate a commitment to their safety and are often better prepared to handle unexpected situations on the road. In addition, many regions encourage or mandate helmet use as part of their cycling safety laws. This proactive approach to personal safety can also influence others in the cycling community to adopt similar practices, thereby cultivating a safer environment for all road users.

While riding on sidewalks might seem safer, it can actually pose risks, as pedestrians have the right of way there. Pedaling at maximum speed can lead to loss of control and increased severity in accidents, while ignoring traffic signals can lead to dangerous situations. Thus, wearing a helmet is the most effective way to enhance a cyclist's safety.
