Final answer:
Bicycle riders should obey traffic laws and signals and wearing a helmet is recommended for safety. They do not always have the right of way and should not ride against traffic. Option b and d are correct.
Step-by-step explanation:
Bicycle riders are expected to adhere to traffic laws and signals, with the imperative responsibility of obeying the same rules as motorists. An essential facet of safe cycling includes the conscientious observance of traffic regulations, fostering a harmonious coexistence between bicycles and motor vehicles. The adoption of helmets is not merely a matter of personal choice; it stands as a health-conscious decision integral to preventing nervous system injuries. While helmet usage regulations may vary by location, the overarching consensus leans towards considering it a best practice for safety.
Riding against traffic, a practice both hazardous and often prohibited by law in numerous regions, is discouraged due to its potential dangers. Bicycle riders must recognize that the right of way is not unconditionally theirs; instead, they are obligated to navigate traffic with an understanding that they share the road and must abide by established rules. Helmets play a pivotal role in reducing the risk of head injuries, underscoring the significance of their usage as a preventive measure. In essence, the adherence to traffic norms and the incorporation of safety measures, such as wearing helmets, collectively contribute to fostering a secure environment for both cyclists and other road users.
