Bicycle Accident Statistics

Injured in a Bicycle Accident?

Bicycle accidents make up about 2 percent of all traffic fatalities each year, killing 900 people—200 of them children. According to the latest statistics available, in 2014, 567,700 people also sought emergency treatment for injuries suffered while cycling.

The following figures were the most up-to-date statistics at the time of our latest research. If you have any questions, or require more recent information, please refer to our sources at the bottom of this page for more information.

National Statistics on Bicycle Injuries and Fatalities

The Insurance Institute for Highway Safety reports that the most prevalent and serious injuries suffered in bicycle accidents are to the head, which reinforces the importance of wearing a helmet.

Just how important is it to wear a helmet? Consider this:

  • It's estimated that the proper use of helmets could reduce a bicyclist's risk of suffering a head injury by as much as 50 percent.
  • Wearing a helmet while riding is estimated to reduce a bicyclist's risk of suffering an injury to the head, face or neck by about 33 percent.
  • The odds that a bicyclist will wear a helmet are four times greater after laws are enacted that require their use.
  • 60 percent of bicyclists killed in 2014 were not wearing helmets.

Alcohol, time of year, and time of day were factors in many bicycle accidents. According to statistics:

  • Of bicyclists 16 and older who were killed in a biking accident in 2014, 21 percent had a blood-alcohol content (BAC) of more than .08 percent, which is the legal limit for intoxication.
  • Bicyclist deaths in 2014 were highest in the months of August, September and October.
  • Bicyclist deaths in 2014 were lowest in the month of February.
  • Bicycle deaths in 2014 spiked between the hours of 6 p.m. and 9 p.m.
  • In 2014, 68 percent of bicyclist fatalities occurred in urban areas.
  • 35 percent of bicyclist deaths happened at intersections.

Age also appears to be a factor in bicycle accidents. According to the most recent statistics available:

  • Since 1975, fatal accidents involving cyclists younger than 20 have decreased by 88 percent.
  • Conversely, during that same span of time, fatal accidents involving bicyclists 20 and older has tripled.

Pennsylvania Bicycle Accident Statistics

In Pennsylvania, bicycle accidents make up about 1.1 percent of the total traffic crashes, and 1.6 percent of all traffic deaths.

According to statistics from the Pennsylvania Department of Transportation (PennDOT), 19 people died as a result of bicycle accidents in 2014, the most recent number available.

Bicycle accident statistics for 2015 and 2016 have not yet been released.

While the number of riders injured in bicycle crashes in Pennsylvania has remained relatively steady over the years, the number of fatalities spiked between 2013 and 2014, when there were 11 and 19 deaths, respectively.

According to 2014 statistics compiled by PennDOT:

  • About 25 percent of riders injured or killed in a bicycle accident, 25 percent are children.
  • About 15.5 percent of riders injured or killed in a bicycle accident are between the ages of 15 and 19.
  • The majority of bike injuries happen during daylight hours.
  • However, 47 percent of fatal bicycle accidents happen during the dark hours of the day.
  • The majority of bicyclist injuries occurred while negotiating an intersection.
  • However, the majority of cyclist deaths occurred at non-intersections.
  • Generally, bicyclists are more likely to be injured in areas where there are no traffic control devices (such as stop signs and traffic lights), and are more likely to be involved in a fatal accident in areas where traffic devices are present.
