To enhance your visibility while riding at night, which action is recommended?

Using reflective clothing is recommended for enhancing visibility while riding at night because it significantly increases the likelihood that other drivers and road users will see you. Reflective materials bounce light from vehicle headlights back toward the driver, making you more conspicuous in low-light conditions. This is crucial for maintaining safety on the road, as being visible to others can help prevent accidents.

The other options do not contribute to increasing visibility in the same effective manner. Keeping the engine running does not impact visibility; it is merely a function of the motorcycle. Avoiding any lights contradicts the need for increased visibility since lights are essential for being seen. Riding in dark clothing is counterproductive, as it makes it harder for others to see you against the dark background of the night. Thus, reflective clothing is the best choice for improving night visibility.
