Speeding Statistics
Survival Strategies

Speeding is one of the most prevalent factors contributing to traffic crashes. The economic cost to society of speeding-related crashes is estimated by NHTSA to be $40.4 billion per year. In 2002, speeding was a contributing factor in 31% of all fatal crashes, and 13,713 lives were lost in speeding-related crashes.

Speeding reduces a driver’s ability to steer safely around curves or objects in the roadway, extends the distance necessary to stop a vehicle, and increases the distance a vehicle travels while the driver reacts to a dangerous situation. Despite that, most drivers believe speeding is OK. In a national Drive for Life poll conducted last year by Mason-Dixon, 71% of drivers – even seniors – said they speed and most believe it’s OK to routinely exceed the speed limit by 5 mph. One in three men surveyed believe it’s OK to exceed the speed limit by 10 mph.

Most crashes (57%) occur at 40 mph or less, but most fatal crashes occur at top speeds. More than half of fatal crashes in 2002 occurred on roads with posted speed limits of 55 mph or more. But these roads are not necessarily in urban areas. In fact, 42% of all motor vehicle fatalities occurred on rural roads with cars traveling at 55 mph or greater.

Speeding also leads to excessive lane changes, which contribute to crashes. More than 43% of all motor vehicle crashes reported in 2001 involved a lane change or road departure. The U.S. Department of Transportation reports 55% of fatal accidents are caused by unintended lane departure, including veering off the road.

But slower speeds alone don’t guarantee safety especially in congested, urban areas. Of slow-speed crashes (30 mph or less) that resulted in a fatality, 75% occurred in urban settings.

Speeding statistics

  • The 2001 costs of speeding-related crashes were estimated to be $40.4 billion — $76,865 per minute or $1,281 per second.
  • At least eight in 10 younger drivers report speeding at least monthly on each road type.
  • Six in 10 drivers age 65 or older report speeding on all road types. (NHTSA, NCSA Traffic Safety Facts, 2002)

Survival strategies

  • Drive the speed limit. Speeding limits your ability to steer safely around curves or objects in the road and extends the distance needed to stop.
  • Don’t let the car behind you pressure you to speed . let them pass you.
  • Slow down even below the speed limit in rainy, icy or snowy weatheror on a road that is under construction.
  • Don’t tailgate. Allow three seconds or more between the time when the car in front of you passes a fixed object and when you pass it.
  • Generally keep pace with the flow of traffic. Driving much slower than the cars around you also can increase the chances of a collision.
