Welcome back to the 2019 SafeTREC Traffic Safety Facts blog series, where we feature recent data on some of California's most pressing traffic safety issues! Explore our recent posts on:
Collisions involving motorcycles are a major traffic safety concern in the United States. Motorcycle riders comprise a disproportionate share of all injured and killed vehicle occupants. In 2016, motorcycle riders were 28 times more likely than passenger car occupants to be fatally injured in a traffic collision, per vehicle miles traveled. The primary countermeasures used to address this problem have included motorcycle helmet laws and other helmet-oriented programs, rider training and licensing programs, vehicle enhancements, including anti-lock braking technology, rider conspicuity...
In 2016, there were 5,286 motorcycle riders killed on public roadways in the United States, a 5.1 percent increase from 2015. Motorcyclists are at greater risk of injury during collisions—in 2016, motorcyclists were 28 times more likely than passenger car occupants to be fatally injured in a traffic collision, per vehicle miles traveled. In 2016 only 65.3 percent of U.S. motorcyclists wore helmets. In states with universal helmet laws requiring all riders to wear helmets, the known helmet use rate among fatally injured motorcyclists ranged from 66 percent to 100 percent in 2016, while in...
California has long been a center of motorcycling and is home to much of the motorcycle industry. In fact, the state has more motorcyclists than any other US state. There are more than 800,000 registered motorcycles in the state, followed by 550,000 in Florida and 445,000 in Texas. As a consequence, California is also a leader in motorcycle collision-related deaths each year.
Welcome back to the SafeTREC Traffic Safety Facts blog series! Each day this week we have featured recent data on some of California's most pressing traffic safety issues. Today, we will be wrapping up the week with the facts on motorcycle safety. In case you missed them, check out the fact sheets on alcohol-impaired driving, aging road users,...
Crash data is readily available and accessible for public use through government information databases. Crash data typically entails vehicle-related injuries and fatalities that were reported to police authorities. But what about unreported incidents--incidents that only require exchange of contact and insurance information, incidents that may not involve an injury or injuries that might not have been reported? As a way to understand perceptions and experiences of safety in communities, UC Berkeley SafeTREC is developing an online data tool that allows people to self-report...
The use of novelty motorcycle helmets is often prompted by beliefs that wearing a standard helmet can contribute to neck injury during traffic collisions. The goal of this analysis was to examine the association between helmet type and neck injury risk and the association between helmet type and head injury. Data were collected during the investigation of motorcycle collisions of any injury severity by the California Highway Patrol (CHP) and 83 local law enforcement agencies in California between June 2012 and July 2013. We estimated head injury and neck injury risk ratios from data on...
Most studies find strong evidence that motorcycle helmets protect against injury, but a small number of controversial studies have reported a positive association between helmet use and neck injury. The most commonly cited paper is that of Goldstein (1986). Goldstein obtained and reanalyzed data from the Hurt Study, a prospective, on-scene investigation of 900 motorcycle collisions in the city of Los Angeles. The Goldstein results have been adopted by the anti-helmet community to justify resistance to compulsory motorcycle helmet use on the grounds that helmets may cause neck injuries due...
To compare the risk of fatal injury across helmet types among collision-involved motorcyclists.
METHODS:
We used data from a cohort of motorcyclists involved in police-reported traffic collisions. Eighty-four law enforcement agencies in California collected detailed information on helmet and rider characteristics during collision investigations in June 2012 through July 2013. Multiply-adjusted risk ratios were estimated with log-binomial regression.
RESULTS:
The adjusted fatal injury risk ratio for novelty helmets was 1.95 (95% CI 1.11-3.40, p...
Road deaths are forecast to double by 2020, with the burden falling most heavily on low- and middle-income countries and, within those countries, on the most vulnerable and poorest road users. Half of the 1.2 million people killed and 50 million injured in road crashes each year are pedestrians, motorcyclists, bicyclists, and users of unsafe public transport; and more than 90 percent are from low- and middle-income countries. Because these are the areas where rapid motorization is taking place, the issue of safety in increasingly multi-modal environments is now of critical importance...
