Motorcycle deaths hit 5,932 in 2021, the highest level since 1975, yet the leading causes are often avoidable and surprisingly specific. One 56% figure from a 2020 IIHS study points to other drivers failing to see motorcyclists, while helmet use and intersection behavior can shift outcomes dramatically. As you look through the crash breakdowns, you will see how speed, left turns, rider experience, and roadway conditions collide in ways that do not show up in everyday driving assumptions.

Interpretation
Causes Interpretation
While motorcyclists certainly face heightened risks from their own actions like speed, impairment, and inexperience, these statistics paint a stark portrait of a two-wheeled war zone where the most common enemy is an inattentive, yielding-violating, left-turning, or simply unseeing driver piloting a two-ton metal box.
