Cell Phones & Auto Accidents

Many factors contribute to every accident, including road conditions and the condition of the vehicles involved, as well as the state of the driver and whether pedestrians or animals are in the roadway. In recent years, the use of cell phones, for talking or texting, has become a widely studied factor in car crash statistics.

Harvard researchers performed a study in 2009, finding an estimated one in 20 traffic accidents in the U.S. involve a driver talking on a cell phone. Joshua Cohen, a researcher at the Harvard Center for Risk Analysis, said We calculate that around 2,600 people die each year as a result of this use of the technology. Another 330,000 are believed to be injured. According to the findings, a cell user has an approximate 13/1,000,000 chance of being killed in a car crash while making a call.

While using your cell phone while driving may not be wise, it is not the only safety measure that can save your life paying attention and driving free of stress or distractions are key to accident prevention.

Main Auto Accident Causes: Drivers, Vehicles & Roads

The National Highway Traffic Safety Administration attributes most auto accidents to one of three causes: drivers, vehicles and roads. There are a number of conditions in each category that can cause an accident.


  • Inadequate surveillance
  • Internal or external distraction
  • Cell phone use
  • Inattention and daydreaming
  • Driving too fast for conditions or a curve
  • Incorrectly anticipating actions of other drivers
  • Illegal maneuvering
  • Driving aggressively and following too closely
  • Overcompensating or poor directional control
  • Panic or freezing
  • Sleeping
  • Heart attack


  • Failed tired or degraded wheels
  • Brake failure or degradation
  • Steering, suspension, transmission or engine failure

Roads & Weather

  • Slick roads from ice or loose debris
  • Visual obstructions
  • Road design
  • Placement of signs or signals

An auto accident can by caused by any of these factors, or a combination of several. It is important for drivers to practice defensive driving techniques, because even the perfect driver can be affected by road conditions, unexpected vehicle failure or other drivers who may not be as cautious.
