Which of the following is a safe practice for riding a moped at night?

Wearing reflective clothing to increase visibility is a crucial safety practice when riding a moped at night. Reflective clothing helps enhance a rider's visibility to other motorists, especially in low-light conditions. It allows drivers to see the rider from a greater distance, which is essential for preventing accidents. At night, visibility is significantly reduced, making it imperative for riders to take extra steps to ensure they can be seen.

In contrast, using only hand signals without the aid of lights may not provide sufficient visibility to others on the road, particularly in the dark. Riding without a headlight, even if streetlights are present, poses a risk as it limits the rider's ability to see the road ahead, and it eliminates the ability for others to see the moped. Additionally, while riding in the center of the lane may sometimes be done for safety reasons, it does not inherently address visibility issues, and improper lane positioning can lead to other hazards.
