Why Motorcycle Crashes on Freeways Can Be Severe
Motorcycle crashes on high-speed roads like State Route 60 often result in serious injuries because riders are unprotected compared to car occupants. Even low-speed collisions can cause harm if the rider is thrown from the bike.
Collisions can occur when drivers fail to notice motorcycles, change lanes abruptly, or misjudge speed and distance. Heavy traffic, blind spots, and merging areas near off-ramps increase the risk.
Wearing protective gear, including helmets, gloves, and armored clothing, can help reduce the severity of injuries. Riders should also remain aware of surrounding vehicles and avoid sudden maneuvers to reduce the risk of crashes on freeways.
