Why should a motorcycle rider avoid riding in a straight line behind a vehicle?

Riding in a straight line behind a vehicle can significantly decrease a motorcycle rider's visibility and increase the risk of rear-end collisions. When a motorcycle is directly behind a larger vehicle, such as a car or truck, the rider is less visible to other drivers, especially if those drivers are attempting to change lanes or make turns. This can lead to dangerous situations where the motorcycle may not be seen in time for safe maneuvering.

By avoiding this position, the rider maintains a better line of sight and can anticipate potential hazards more effectively. Additionally, establishing a position where they can be seen by other motorists allows the rider to react proactively to the movements of the vehicle in front. Maintaining an appropriate distance and adjusting position also provides the rider with more time to react to sudden stops or braking by the vehicle ahead, thereby reducing the chances of a collision.

Other options, such as saving fuel or reducing wind resistance, are not directly related to safety concerns associated with visibility and collision risks. Thus, prioritizing visibility and avoiding potential rear-end collisions is the primary reason for maintaining a safe riding position behind other vehicles.
