Final answer:
Bicyclists are more likely to be seriously injured in a collision with a car and must ride in the same direction as traffic. Wearing helmets can help prevent serious head injuries.
Step-by-step explanation:
The correct statement regarding bicycle riders is that they are likely to be seriously injured in almost any collision with a car. Bicyclists must always ride in the direction of traffic, not facing it. This is for their safety as well as to follow traffic regulations.
Bicycle helmets are a key safety measure that can help to protect cyclists from head injuries. If a collision were to occur, wearing a helmet could potentially prevent or reduce the severity of nervous system injuries.
