Helmet Use And Effectiveness, Alcohol Involvement In Motorcycle Crash Incidences

The National Highway Traffic Safety Administration (NHTSA) is a federally-funded agency that studies vehicle accidents, including causes, frequency and other data. The agency recently completed a study of motorcycle accidents, publishing its findings in 2008. You can view a complete copy of the study on their website at The report illustrates the stark reality that motorcycle riders run a far greater risk of injury and fatality from traffic accidents. Some highlights from the report:

  • Almost 100,000 motorcyclists were injured in accidents in 2008.
  • Over 5,000 were killed in traffic accidents in 2008
  • Motorcyclists are approximately 37 times more likely to suffer a fatal accident when compared with car occupants, and 9 times more likely to be injured.
  • Wearing a helmet reduces the risk of a fatal accident by 37%
  • Have fun on your bike but be safe.

Traffic Safety Facts - 2008 Data

In 2008, 5,290 motorcyclists were killed—an increase of 2 percent over the 5,174 motorcyclists killed in 2007. There were 96,000 motorcyclists injured during 2008. An estimated 148,000 motorcyclists have died in traffic crashes since the enactment of the Highway Safety and National Traffic and Motor Vehicle Safety Act of 1966. Motorcycles made up nearly 3 percent of all registered vehicles in the United States in 2007 and accounted for only 0.4 percent of all vehicle miles traveled. Per vehicle mile traveled in 2007, motorcyclists were about 37 times more likely than passenger car occupants to die in a motor vehicle traffic crash and 9 times more likely to be injured.

Motorcycle Involvement in Crashes

Motorcycle vs. automobile accidents often occur because the auto driver did not see the motorcycle. Therefore, most of these accidents are caused by the negligence of the driver of the auto. In 2008, 2,554 (47%) of all motorcycles involved in fatal accidents crashed into another type of motor vehicle. In two-vehicle crashes, 77 percent of the motorcycles involved were struck in the front. Only 7 percent were struck in the rear.

Motorcycles are more likely to be involved in a fatal collision with a fixed object than are other vehicles. In 2008, 25 percent of the motorcycles involved in fatal crashes collided with fixed objects, compared to 19 percent for passenger cars, 14 percent for light trucks, and 4 percent for large trucks.

In 2008, there were 2,387 two-vehicle fatal crashes involving a motorcycle and another type of vehicle. In 41 percent (985) of these crashes the other vehicle was turning left while the motorcycle was going straight, passing, or overtaking the vehicle. Both vehicles were going straight in 666 crashes (28%).

In 2008, 35 percent of all motorcycle riders involved in fatal crashes were speeding, compared to 23 percent for passenger car drivers, 19 percent for light-truck drivers, and 8 percent for large-truck drivers. NHTSA considers a crash to be speeding-related if the driver was charged with a speeding-related offense or if an officer indicated that racing, driving too fast for conditions, or exceeding the posted speed limit was a contributing factor in the crash.


In fatal crashes in 2008 a higher percentage of motorcycle riders had blood alcohol concentration (BAC) of .08 grams per deciliter (g/dL) or higher than any other type of motor vehicle driver. The percentages for vehicle riders involved in fatal crashes were 29 percent for motorcycles, 23 percent for passenger cars, 23 percent for light trucks, and 2 percent for large trucks.

In 2008, 30 percent of all fatally injured motorcycle riders had BAC levels of .08 g/dL or higher. An additional 7 percent had lower alcohol levels (BAC .01 to .07 g/dL).

The percentage with BAC .08 g/dL or above was highest for fatally injured motorcycle riders among two age groups, 40–44 (41%) and 45–49 (41%) followed by the 35–39 (36%) age group.

Forty-three percent of the 2,291 motorcycle riders who died in single-vehicle crashes in 2008 had BAC levels of .08 g/dL or higher. Sixty-four percent of those killed in single-vehicle crashes on weekend nights had BACs of .08 g/dL or higher.

Helmet Use and Effectiveness

Make your own decision but know the FACTS first.

NHTSA estimates that helmets saved the lives of 1,829 motorcyclists in 2008. If all motorcyclists had worn helmets, an additional 823 lives could have been saved.

Helmets are estimated to be 37-percent effective in preventing fatal injuries to motorcycle riders and 41-percent for motorcycle passengers. This means for every 100 motorcycle riders killed in crashes while not wearing a helmet, 37 of them could have been saved had all 100 worn helmets. According to NHTSA's National Occupant Protection Use Survey, a nationally representative observational survey of motorcycle helmet, seat belt, and child safety seat use, use of DOT-compliant helmets in 2008 stood at 63 percent, a gain from 58 percent in 2007. Reported helmet use rates for fatally injured motorcyclists in 2008 were 59 percent for riders and 49 percent for passengers, compared with 59 percent and 47 percent, respectively, in 2007.

New statistics published by California's Office of Transportation Safety show that motorcycle fatalities decreased 10.7 percent from 2009 to 2010. However, 79% of motorcycle operators involved in fatal collisions were at fault, and 57% of motorcycle operators involved in injury collisions were at fault.

Further, the percentage of motorcycle operators killed with a Blood Alcohol Content (BAC) of 0.08 or greater increased from 23 percent in 2009 to 27 percent in 2010. There are several theories that try to explain why the fatality rate is lower for motorcyclists with a BAC of 0.08 or greater. The most likely reason for this decrease is the fact that motorcycles can be difficult to ride and require a greater degree of skill and concentration. This means that riders who are under the influence are less likely to get very far on a motorcycle and are often involved in smaller accidents.

The percentage of motorcycle operators killed that were improperly licensed increased from 32 percent in 2009 to 33 percent in 2010. While this increase is less significant, it still reflects a population of riders who do not regularly ride motorcycles.
