Which of the following is NOT a safety precaution for motorcyclists?

Wearing a helmet, using turn signals, and wearing protective clothing are all essential safety precautions that significantly enhance a motorcyclist's safety on the road. Wearing a helmet protects the head during a crash, which is crucial as head injuries are among the most serious types of injuries for motorcyclists. Using turn signals is vital for communication with other road users, helping to indicate intentions and improve overall traffic safety. Protective clothing, such as jackets, pants, and gloves made from durable materials, serves to protect against abrasions and injuries in the event of a fall or accident.

On the other hand, riding without a license is not a safety precaution; rather, it represents a violation of the law that compromises the safety of both the motorcyclist and others on the road. A license is a confirmation that the rider has met the necessary training and knowledge requirements to operate a motorcycle safely. Riding without this qualification increases the risk of accidents due to a lack of proper skills and understanding of traffic laws.
