Why is a motorcycle considered less visible than other vehicles?

A motorcycle is considered less visible than other vehicles primarily due to its lower profile. This means that motorcycles are closer to the ground compared to many larger vehicles, making them less noticeable to other drivers, especially in traffic situations where their sight lines may be obstructed by taller vehicles. Additionally, motorcycles often occupy a smaller visual footprint on the road, which can make them blend into the environment more easily. The combination of their lower height and smaller size contributes to reduced visibility, leading to a higher risk of accidents if drivers do not actively look for motorcycles.

While factors like speed, size, and color can influence visibility, the lower profile is a significant reason that tends to diminish the awareness of motorcyclists among other road users.
