What is a general rule regarding moped riders and road hazards?

Moped riders should always be prepared to react to unforeseen hazards quickly because the ability to respond effectively can significantly enhance safety on the road. Moped riders are often more vulnerable than other vehicles due to their smaller size and lower speed, making it crucial for them to remain alert to potential dangers such as potholes, debris, wet surfaces, or the actions of other drivers. Being prepared to react means maintaining situational awareness and having the skills to navigate around obstacles or adjust speed seamlessly.

The other options do not present safe riding practices. Central lane positioning may not always be effective or safe, especially in certain traffic conditions. Driving over road hazards without caution can lead to accidents or loss of control. Lastly, not using mirrors would greatly impede a rider's awareness of their surroundings, which is essential for safe navigation. Therefore, the emphasis on being prepared to react quickly stands out as the most vital guideline for moped safety.
