Which action enhances safety when riding in traffic?

Wearing bright, reflective gear significantly enhances safety when riding in traffic because it increases the motorcycle rider's visibility to other road users. In various lighting conditions, such as at dusk, dawn, or during inclement weather, reflective clothing can help ensure that riders are seen by drivers, thereby reducing the risk of accidents. Visibility is a critical factor in preventing collisions, as many accidents occur because drivers do not see the motorcycle in time to react appropriately.

The other options do not provide the same level of safety enhancement. Riding in between lanes, while sometimes practiced, can increase risk if not done with caution, as it may lead to underestimating the space needed by other vehicles. Only looking straight ahead limits awareness of surroundings, crucial for traffic safety, and using only hand signals may not be sufficient for communication with other road users, especially in busy or complex traffic situations. This reinforces the importance of being visible through proper clothing as a fundamental safety measure.
