What are common causes of vehicle accidents?

Distracted driving and speeding are indeed common causes of vehicle accidents. Distracted driving encompasses behaviors such as texting, talking on the phone, eating, or adjusting the radio, which can divert a driver's attention away from the road. When a driver is distracted, they may not react quickly enough to changing traffic conditions or obstacles, increasing the likelihood of a collision.

Speeding, on the other hand, reduces the driver's ability to steer safely around curves or obstacles, extends the distance necessary to stop a vehicle, and increases the severity of a crash if one occurs. High-speed collisions tend to result in more severe injuries or fatalities due to the increased force and momentum involved.

While other options mention potentially hazardous situations, they either include behaviors that are generally aimed at safety, like wearing a seatbelt, or do not reflect the primary and proven causes of accidents as effectively as the combination of distracted driving and speeding does.
