Final answer:
The risk of being in a run-off the road crash is increased by driver error, distractions, speeding, environmental conditions, and the design and condition of the vehicle.
Step-by-step explanation:
Factors that increase the risk of being in a run-off the road crash can include a variety of behavioral, environmental, and vehicular issues. Driver error is a major factor, accounting for approximately 54 percent of all fatal auto accidents. Distractions, such as using a cell phone, eating, or adjusting the radio, can cause a driver to lose focus and veer off the road. Speeding is another significant risk factor, as it reduces the driver's ability to react to road conditions or obstacles in time to avoid a crash.
Environmental conditions such as inclement weather, poor road maintenance, or inadequate signage can confuse or impair a driver's ability to navigate safely. The design and condition of the vehicle also play a role; for example, cars today often have plastic components that crumple upon impact, providing a longer collision time and lessening the force experienced by occupants, thus potentially reducing the severity of an accident.
