Motorcycle Crashes

APRIL  2016

UP FRONT
  • In 2014, 4,586 people died in motorcycle crashes, down 2.3 percent from 4,692 in 2013, according to a National Highway Traffic Safety Administration (NHTSA) report.
  • In 2014, 92,000 motorcyclists were injured, up 4.5 percent from 88,000 in 2013.
  • In 2013, motorcyclists were about 26 times more likely than passenger car occupants to die in a crash per vehicle mile traveled and five times more likely to be injured.
  • There were about 8.4 million motorcycles on the road in 2013.



THE TOPIC

In 2014 motorcycle fatalities fell 2.3 percent to 4,586 from 4,692 in 2013.  This was the second decrease in motorcyclist fatalities since 2009. In 2013, 56 out of every 100,000 registered motorcycles was involved in a fatal crash, compared with only 9 out of every 100,000 passenger cars, according to the National Highway Traffic Safety Administration (NHTSA). In 2013 motorcyclists were about 26 times more likely than passenger car occupants to die in a crash per vehicle mile traveled and five times more likely to be injured, according to NHTSA.
(Note: statistics on fatal motorcycle crashes are also available from the Insurance Institute for Highway Safety.)

KEY FACTS

  • 2014 Crash Data: According to the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA), in 2014, 4,586 people died in motorcycle crashes, down 2.3 percent from 4,692 in 2013.
  • In 2014, 39 percent of those motorcyclists killed were not wearing helmets, down from 41 percent in 2013.
  • In 2014, 92,000 motorcyclists were injured, up 4.5 percent from 88,000 in 2013, almost as many as the 93,000 injured in 2012.
  • 2013 Crash Data: According to the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA), in 2013, 4,668 people died in motorcycle crashes, down 6.4 percent from 4,986 in 2012.
  • According to the latest data available from the Federal Highway Administration, there were 8.4 million private and commercial motorcycles on U.S. roads in 2013, compared with 8.0 million in 2009.
  • Over the nine years from 2004 to 2013, fatalities among the 40-and-older age group increased by 39 percent, according to NHTSA, compared to 16 percent for all ages.
  • Motorcyclists were about 26 times more likely than passenger car occupants to die in a crash per vehicle mile traveled in 2013 and five times more likely to be injured, according to NHTSA.
  • The fatality rate per registered vehicle for motorcyclists in 2013 was six times the fatality rate for passenger car occupants, according to NHTSA.
  •  Motorcycle Theft: The National Insurance Crime Bureau (NICB) reported that motorcycle thefts fell 6 percent in 2014 to 42,856 from 45,367 a year earlier, based on data from the National Crime Information Center of the FBI. The decrease occurred despite a 4 percent increase in motorcycle sales, according to the NICB as reported by the Motorcycle Industry Council.
  • The NICB’s report also details the seasonal nature of motorcycle thefts. More motorcycles are stolen during warm months—July and August had the most motorcycle thefts in 2014 while January and February had the fewest. The top five makes stolen in 2014, from highest to lowest, were American Honda Motor Co., Yamaha Motor Corporation, American Suzuki Motor Corporation, Kawasaki Motors Corp. and Harley-Davidson Inc. California had the most motorcycle thefts in 2014, followed by Florida and Texas. By city, Las Vegas, Nevada, had the most thefts, followed by New York, New York, and San Diego, California.
  • The recovery rate of 2014 motorcycle thefts was 41 percent. The number of motorcycles recovered fell 1 percent from 2013 to 2014.

FATALITIES AND INJURIES

According to the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) the following terms are used to define motorcycle occupants: a motorcycle rider is the operator only; a passenger is any person seated on the motorcycle but not in control of the motorcycle; and any combined reference to the motorcycle rider (operator) as well as the passenger will be referred to as motorcyclists.
According to NHTSA,  in 2014, 4,586 people died in motorcycle crashes, down 2.3 percent from 4,692 in 2013. In addition, 92,000 motorcyclists were injured, up 4.5 percent from 88,000 in 2013, almost back to the level of 2012 when 93,000 people were injured in motorcycle crashes. In 2014, 39 percent of the motorcyclists killed were not wearing helmets, down from 41 percent in 2013.
NHTSA says that in 2013, 4,668 motorcyclists died in crashes, down 6.4 percent from 4,986 in 2012. In 2013, 88,000 motorcyclists were injured in accidents, down 5.4 percent from 93,000 in 2012. In 2013 motorcyclists accounted for 14 percent of all traffic fatalities. Motorcyclists made up 4 percent of all people injured, 18 percent of all occupants (driver and passenger) fatalities, and 4 percent of all occupants injured. Of the 4,668 motorcyclists killed, 94 percent were riders and 6 percent were passengers.
By Age: Older motorcyclists account for more than half of all motorcyclist fatalities. NHTSA data show that in 2013, 55 percent of motorcyclists killed in crashes were age 40 or over, compared with 46 percent in 2004. The number of motorcyclists age 40 and over killed in crashes increased by 39 percent from 2004 to 2013. In contrast, fatalities among all motorcyclists rose 16 percent. NHTSA says that the average age of motorcycle riders killed in crashes was 42 in 2013, compared with 38 in 2004.
Older riders appear to sustain more serious injuries than younger riders. Researchers from Brown University cited declines in vision and reaction time, along with the larger-sized bikes that older riders favor, which tend to roll over more often, and the increased fragility among older people as the causes. The study used data on riders age 20 and over who needed emergency medical care following motorcycle crashes from 2001 to 2008. The riders were put in three groups by age: 20 to 39, 40 to 59, and 60 and over. The data showed that while injury rates were rising for all age groups, the steepest rise occurred in the 60 and over group, who were two and a half times more likely to have serious injuries than the youngest group. They were three times more likely to be admitted to the hospital. The middle and older groups were also more likely to sustain fractures, dislocations and other injuries, such as brain damage, than the youngest group. The authors published findings in the journal Injury Prevention in February 2013. The study is entitled Injury patterns and severity among motorcyclists treated in US emergency departments, 2001–2008: a comparison of younger and older riders.
By Driver Behavior
Alcohol use: According to NHTSA, in 2014, 29 percent of motorcycle riders who were involved in fatal crashes had a blood alcohol concentration (BAC) of 0.08 percent or over (the national definition of drunk driving), up from 27 percent in 2013 and 28 percent in 2012.  This compares with 22 percent of passenger car drivers and light truck drivers involved in fatal crashes, and with 2 percent of large truck drivers.
In 2013, in addition to the 27 percent of all fatally injured motorcycle riders who had BACs of 0.08 percent or higher, another 7 percent had lower alcohol levels (0.01 to 0.07 percent BAC). Fatally-injured motorcycle riders between the ages of 40 to 49 had the highest rate of alcohol involvement (40 percent), followed by the 35 to 39 age group (33 percent).
In 2013 motorcycle riders killed in traffic crashes at night were almost four times more likely to have BAC levels of 0.08 percent or higher (46 percent) than those killed during the day (12 percent).
The reported helmet use rate for motorcycle riders with BACs at or over 0.08 percent who were killed in traffic crashes was 46 percent in 2013, compared with 66 percent for those who did not have any measurable blood alcohol.
Speeding: In 2013, 34 percent of all motorcycle riders involved in fatal crashes were speeding, compared with 21 percent for drivers of passenger cars, 18 percent for light truck drivers and 8 percent for large truck drivers, according to NHTSA.
Licensing: One out of four motorcycle riders (25 percent) who were involved in fatal crashes in 2013 were riding without a valid license, compared with 13 percent of passenger car drivers.
By Type of Motorcycle: According to a 2007 report from the Insurance Institute for Highway Safety (IIHS), riders of “super sports” motorcycles have driver death rates per 10,000 registered vehicles nearly four times higher than those for drivers of other types of motorcycles. Super sports can reach speeds of up to 190 mph. The light-weight bikes, built for racing, are modified for street use and are popular with riders under the age of 30. In 2005 these bikes registered 22.5 driver deaths per 10,000 registered vehicles, compared with 10.7 deaths for other sport models. Standards and cruisers, and touring bikes (with upright handlebars) have rates of 5.7 and 6.5, respectively, per 10,000 vehicles. In 2005 super sports accounted for 9 percent of registrations, and standards and cruisers made up 51 percent of registrations. Among fatally injured drivers, the IIHS says that drivers of super sports were the youngest—with an average age of 27. Touring motorcycle drivers were the oldest, 51 years old. Fatally injured drivers of other sports models were 34, on average; standard and cruiser drivers were 44 years old. Speeding and driver error were bigger factors in super sport and sport fatal crashes. Speed was cited in 57 percent of super sport fatal crashes in 2005 and in 46 percent for sport model riders. Speed was a factor in 27 percent of fatal crashes of cruisers and standards and 22 percent of touring models.

LOSSES

Collision Losses by Type: A 2014 Highway Loss Data Institute report shows that super sport motorcycles had the highest relative overall losses when compared with nine other motorcycle classes. Based on collision coverage results for 2009 to 2013 model motorcycles insured under private passenger motorcycle policies, relative overall losses for super sport models were indexed at 345, compared with 100 for all motorcycles. The high overall losses for super sport models was driven up by their high claim frequency. Super sports have engines that deliver more horsepower per pound than a typical NASCAR vehicle, reaching speeds of nearly 190 miles per hour and are built on racing platforms but are modified for the highway.
The Government Accounting Office (GAO) estimated that in 2010 motorcycle crashes cost $16 billion in direct costs such as emergency services, medical costs including rehabilitation, property damage, loss of market productivity including lost wages, loss in household productivity and insurance costs, including claims and the cost of defense attorneys. The GAO found that market productivity loss produced the largest cost, 44 percent of total costs, followed by medical costs, at 18 percent. Other costs such as long-term medical costs were not included. The GAO recommends that NHTSA grants to states for motorcycle safety, which totaled $45.9 million from fiscal years 2006 to 2012, be expanded from motorcyclist training and motorist awareness efforts to include programs that increase helmet use, safety awareness and educating police about motorcycle safety. In addition, the GAO urges NHTSA to identify research priorities, conduct research on promising strategies, implement a graduated licensing model (See Insurance Issues Updates: Teen Drivers) and encourage motorcyclists to improve their visibility to other motorists. The study is entitledIncreasing Federal Funding Flexibility and Identifying Research Priorities Would Help Support States’ Safety Efforts.

SAFETY ISSUES

Training Courses: The Motorcycle Safety Foundation (MSF, http://www.msf-usa.org), sponsored by motorcycle manufacturers and distributors, works with the National Highway Traffic Safety Administration (NHTSA), state governments and other organizations to improve motorcycle safety through education, training and licensing. Since 1974 about 6 million motorcyclists have taken MSF training courses. The organization also works with the states to integrate rider safety and skills in licensing tests. It also promotes safety by recommending motorcycle operators wear protective gear, especially helmets, ride sober and ride within their skill limits.
As of February 2013, three states (Connecticut, Delaware and Tennessee) mandated insurance discounts for motorcycle drivers who complete approved motorcycle training courses, according to the National Association of Insurance Commissioners.
Antilock Braking Systems (ABS): Stopping a motorcycle is more complex than stopping a car. Motorcycles have separate brakes for the front and rear wheels, and braking hard can lock the wheels and cause the bike to overturn. Not braking hard enough can put the rider into harm’s way. With ABS, a rider can brake fully without fear of locking up. The system automatically reduces brake pressure when a lockup is about to occur and increases it again after traction is restored. The Insurance Institute for Highway Safety (IIHS) said in March 2010 that motorcycles with antilock brakes versus those without are 37 percent less likely to be in fatal crashes. The IIHS’s affiliate, the Highway Loss Data Institute (HLDI), found that collision claims were filed 23 percent less often for antilock-equipped motorcycles than for the same models without antilock brakes. Medical claims related to riders’ injuries were 34 percent less frequent than with bikes that did not have antilock brakes. HLDI studied ABS and non-ABS versions of 22 motorcycles from the 2003-2012 model years. In addition the 2012 analysis found that motorcyclists with antilock brakes were 30 percent less likely to have a collision claim within the first 90 days of a policy and 19 percent less likely afterward.
Airbags: Honda Motorcycle Company is the first company to offer the option of an airbag, which is available on one of the most expensive models. The option became available in 2006. A handful of companies have recently developed wearable airbags, which are worn either inside a jacket or strapped on outside. No data on the effectiveness of these new items has been published.
Motorcycle Helmets: According to NHTSA, in 2014 motorcycle helmets saved 1,669 lives. In 2013 motorcycle helmets saved 1,640 lives. Helmets are estimated to be 37 percent effective in preventing fatal injuries for motorcycle riders (operators) and 41 percent effective for motorcycle passengers.
Motorcycle Helmet Use Laws: According to the Insurance Institute for Highway Safety, 19 states and the District of Columbia had laws on the books requiring all motorcyclists to wear helmets as of May 2015. (See chart below). In another 28 states only people under a specific age (mostly between 17 and 20 years of age) were required to wear helmets. Three states (Illinois, Iowa and New Hampshire) had no helmet use laws. A National Highway Traffic Safety Administration (NHTSA) study covering 10 states found that when universal helmet laws, which pertain to all riders, were repealed, helmet use rates dropped from 99 percent to 50 percent. In states where the universal law was reinstated, helmet use rates rose to above 95 percent.
According to NHTSA’s 2014 National Occupant Protection Use Survey, motorcycle helmet use reached 64 percent in June 2014, compared with from 60 percent in 2013 and 2 percentage points lower than in 2011, when 66 percent of motorcyclists wore helmets, a change that NHTSA indicates is not statistically significant. In addition, the survey only counts helmets that comply with Department of Transportation standards. Helmet use among motorcycle passengers was 51 percent in 2014, basically unchanged from 50 percent in 2013. Helmet use by motorcycle riders (operators) rose to 67 percent, up from 62 percent in 2013. Helmet use was highest in the West, at 85 percent, but down from 92 percent in 2013. In the South helmet use rose from 65 percent in 2013 to 78 percent in 2014. Helmet use was 56 percent in the Northeast in 2014, up from 52 percent in 2013 and was 47 percent in the Midwest, up from 42 percent in 2013.
Usage rates are higher in states that have universal laws that require all riders to use helmets. In June 2014, 89 percent of motorcyclists in universal law states wore helmets, basically unchanged from 88 percent in 2013. In states without universal laws, usage was 48 percent in 2014, compared with 49 percent in 2013.
In 2014, 10 times more unhelmeted motorcyclists died (1,565) in states that did not have universal helmet laws than in states that had universal helmet laws (151 unhelmeted motorcyclist fatalities), according to a NHTSA report.
