According to the ​​National Highway Traffic Safety Administration (NHTSA), the leading causes of car accidents include:
Distracted driving: Smartphones, navigation, infotainment systems, and other forms of in-vehicle technology are common causes of distracted driving.
Impaired driving: Driving while under the influence of drugs (illegal or prescription) or alcohol impacts one’s ability to be alert, process information, and react quickly. Likewise, sleepiness and exhaustion also diminish a driver’s capability to control a vehicle.
Speeding: A speeding vehicle is incredibly dangerous and difficult to maneuver safely. The injuries suffered during high-speed collisions can be catastrophic or fatal.
These are some of the most common causes of car accidents, but others may arise like inclement weather on unsafe roads, or issues with the vehicle itself (like improperly made or installed parts).
