What Factors Can Affect Motorcycle and Car Crashes on Busy Highways?
Crashes involving motorcycles and passenger vehicles on highways often happen due to visibility challenges and speed differences. Motorcycles are smaller and can be harder for drivers to see, especially in areas with heavy traffic or limited space.
Lane changes are another common factor. When traffic is dense, drivers may not always notice a motorcycle traveling alongside them. Sudden stops or merging traffic can also increase the risk of a collision.
Road design can add to the risk as well. Narrow lanes, tunnels, or covered highway sections may reduce visibility and reaction time. In busy urban areas, these conditions can make it more difficult for both drivers and riders to respond quickly to changing traffic patterns.
