Almost half of all serious roadside hazard crashes occur on which type of roadway?

The correct answer is that almost half of all serious roadside hazard crashes occur on curves. Curves present unique challenges for drivers due to changes in direction, which can affect vehicle stability and visibility. When a vehicle is navigating a curve, the dynamics of speed and steering become critical; if a driver goes too fast or misjudges the turn, they can easily lose control. Additionally, curves can obstruct the driver’s view of oncoming traffic or potential hazards such as pedestrians, animals, or debris in the roadway.

On curved roadways, factors like centrifugal force come into play, increasing the risk of sliding or rolling over if the vehicle is not handled properly. This leads to a higher incidence of crashes in these areas compared to other types of roadways where visibility and control are less compromised. Understanding the risks associated with driving on curves is crucial for preventing serious roadside hazard incidents.
