Motorcycle Crashes
 |
THE TOPIC
MARCH 2008
Motorcycle riding has become more popular in recent years, appealing to a new group of enthusiasts consisting of older and more affluent riders. Sales of all types of two-wheelers reached about 1,158,000 in 2006, a level not seen in about 30 years. At the same time motorcycle fatalities have also been climbing, reaching their highest level in 2006 since 1981. There has been a dramatic jump in the number of deaths among motorcycle riders age 40 and older in recent years.
Motorcycles are by their nature far less crashworthy than closed vehicles. They are also less visible to other drivers and pedestrians and less stable than four-wheel vehicles. Operating a motorcycle requires a different combination of physical and mental skills than those used in driving four-wheel vehicles. Motorcyclists and their passengers are more vulnerable to the hazards of weather and road conditions than drivers in closed vehicles.
Motorcycle insurance is widely available. As motorcycles became more popular, more insurers entered the market. Now, most of the top ten auto insurers offer motorcycle insurance, either as an endorsement to a personal automobile policy or as a separate policy, in most of the states in which they operate. Many have recently expanded into new states. For more information see Motorcycle Insurance in the Specialty Insurance section of the I.I.I. Web site.

FATALITIES AND INJURIES
Overall: According to the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA, http://www.nhtsa.dot.gov), in 2006, 4,810 motorcyclists died in crashes, up 5.1 percent from 4,576 in 2005, marking the ninth consecutive year of higher motorcycle deaths. Motorcycle fatalities are at their highest level since 1981. From 1997, a historic low, to 2006, motorcycle fatalities rose 127 percent. In 2006, 88,000 motorcycle riders were injured in accidents, 1,000 more than in 2005 and up 60 percent from 55,000 in 1996.
In 2006 motorcyclists accounted for 11 percent of all traffic fatalities, 13 percent of all occupant fatalities and 4 percent of all occupants injured.
By Age: Older motorcycle riders, who account for an increasingly larger proportion of all motorcyclists, now account for about half of all motorcycle rider fatalities. NHTSA data show that in 2006, 47 percent of motorcycle riders killed in crashes were age 40 or over, compared with 30 percent ten years earlier. In contrast, fatalities among young motorcycle riders have declined in the past 10 years, relative to other age groups. In 2006 fatalities in the under 30-year old group dropped to 32 percent from 45 percent in 1996. Fatalities among motorcyclists in the 30-to 39-year-old group fell to 21 percent in 2006 from 26 percent ten years earlier.
By Driver Behavior:
Alcohol use: Motorcycle operators have high incidences of alcohol use. NHTSA says that in 2006, 27 percent of motorcycle operators involved in fatal crashes had a blood-alcohol concentration (BAC) over 0.08 grams per deciliter (the national definition of drunk driving), compared with 23 percent of drivers of passenger cars, 24 percent of light truck drivers and 1 percent of large truck drivers in fatal crashes. These figures take into account fatally injured operators, passengers and/or pedestrians.
Of all fatally injured motorcycle operators, 27 percent had BAC levels of 0.08 or higher in 2006. Another 7 percent had lower alcohol levels (0.01 to 0.07 BAC.). Fatally injured motorcycle operators between the ages of 35 to 39 had the highest percentage of BACs 0.08 and above (41 percent), compared with 39 percent for those ages 40 to 44. Of fatally injured motorcycle operators age 45-49, 34 percent had BACs—0.08 and above. Forty-one percent of the 1,878 fatally injured motorcycle operators who died in single-vehicle crashes in 2006 (for example, those in which the motorcycle crashed into a stationary object) had BAC levels of 0.08 or higher. On weekend nights, the proportion was higher: 59 percent of motorcycle operators who died in single-vehicle crashes had BACs of 0.08 or higher.
Speeding: In 2006, 37 percent of all motorcyclists involved in fatal crashes were speeding, compared with 23 percent for drivers of passenger cars, 19 percent for light truck drivers and 8 percent for large truck drivers, according to NHTSA.
Licensing: Twenty-five percent of motorcycle operators who were involved in fatal crashes were riding without a valid license in 2006, compared with 13 percent of passenger vehicle drivers. NHTSA says that motorcycle operators were also 1.2 times more likely than passenger vehicle drivers to have a prior license suspension or revocation.
By Type of Motorcycle:
According to the Insurance Institute for Highway Safety (IIHS), riders of “supersports” motorcycles have driver death rates per 10,000 registered vehicles nearly four times higher than for drivers of other types of motorcycles. Supersports have more horsepower than conventional motorcycles and can reach speeds of up to 190 mph. They are built on racing platforms and are modified for street use. The bikes are popular with riders under the age of 30. The bikes are light-weight and aerodynamically styled. In 2005, these bikes registered 22.5 driver deaths per 10,000 registered vehicles compared with 10.7 deaths for other sport models (related to supersports but do not have the acceleration, stability and handling of supersports). Standards and cruisers and touring bikes, with upright handlebars, have rates of 5.7 and 6.5 per 10,000 vehicles. In 2005, supersports 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 supersports 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 supersport and sport fatal crashes. Speed was cited in 57 percent of supersport riders’ fatal crashes in 2005 and in 46 percent for sport model riders. Speed was a factor in 27 of fatal crashes of riders of cruisers and standards, and for 22 percent of riders of touring models.
Collision Losses by Type: The IIHS says that supersports have the overall highest insurance losses under collision coverage among the motorcycle classes, almost four times higher than for touring models and more than six times higher than for cruisers. Nine of the ten motorcycles with the highest losses were supersports. Claim frequency is driving the high losses for supersports, meaning that they are involved in more collisions than other types of motorcycles—there were 9 claims per 100 insured vehicle years for supersports models, compared with 2.3 for all models. The models surveyed were all 2002-2006 models. Touring motorcycles had the most expensive claims because they are the most expensive to purchase. Supersport models are the most popular with thieves—with average loss payments for theft losses per insured vehicle years of $246 for 2002-2006 models, seven times higher than the average for all motorcycles. Supersport models had the highest frequency of thefts—31.8 per insured vehicle year, compared with cruisers and touring models which had the lowest at 1.1 claims per insured vehicle year. However, touring models had the highest average loss payments—$15,696, reflecting their high purchase price and upgrades.
Thefts: The National Insurance Crime Bureau (NICB) and LoJack Corporation, a manufacturer of electronic vehicle tracking and recovery systems, found that 67 percent of motorcycle owners who participated in an online survey are at high risk for motorcycle theft. The survey, which was conducted in July and August 2007, found that the high risk resulted from owners not taking precautions such as securing their motorcycles to an immovable object when parked, or arming their bikes with alarms, kill switches and recovery systems. Respondents scored better by applying common sense theft protection measures such as parking in a concealed area at home or in a well-lit area in a parking lot and never leaving the keys on a parked bike. According to the NICB, 71,523 motorcycles were stolen in 2006, a 137 percent rise since 2000.

SAFETY ISSUES
The Motorcycle Safety Foundation (MSF, http://www.msf-usa.org), sponsored by motorcycle manufacturers and distributors, works with NHTSA, state governments and other organizations to improve motorcycle safety through education, training and licensing. Since 1973 about 3.2 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.
Motorcycle Helmets: In 2006 motorcycle helmets saved 1,658 lives. NHTSA says that if all motorcyclists had worn helmets, 752 more lives would have been saved. Helmets are estimated to be 37 percent effective in preventing fatal injuries.
A 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.
Motorcycle Helmet Use Laws: According to the Insurance Institute for Highway Safety, 20 states and the District of Columbia had laws on the books requiring all motorcyclists to wear helmets as of June 2007 (See chart below). In another 27 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.
According to NHTSA’s National Occupant Protection Use Survey, a nationally representative observational survey, motorcycle helmet use rose to 58 percent in June 2007 from 51 percent in June 2006. Helmet use had been falling from a high of 71 percent in October 2000. Use rates remain lower in states that do not require all riders to use helmets. In June 2007 74 percent of motorcyclists in states requiring helmet use wore them, compared with 42 percent of motorcyclists in states that do not. The survey counts only helmets that comply with Department of Transportation standards. Motorcycle helmet use was highest in the West, at 77 percent and in the South and Northeast, at 58 percent. Helmet use was lowest in the Midwest, at 49 percent.
