Lane Splitting Motorcyclists Safer in TrafficA new study by the University of California Berkeley shows that motorcyclists who split lanes in heavy traffic are significantly less likely to be struck from behind by other motorists and are less likely to suffer head or torso injuries, the American Motorcyclist Association reports.Researchers, led by Dr. Thomas Rice of the Safe Transportation Research and Education Center (SafeTREC), reviewed nearly 6,000 motorcycle-involved traffic collisions between June 2012 and August 2013, including 997 in which the riders were splitting lanes at the time of the crash.

“Perhaps one of the most dangerous situations for any motorcyclist is being caught in congested traffic, where stop-and-go vehicles, distracted and inattentive vehicle operators, and environmental conditions increase the risk of physical contact with another vehicle or hazard,” said Wayne Allard, AMA vice president for government relations. “Reducing a motorcyclist’s exposure to vehicles that are frequently accelerating and decelerating on congested roadways can be one way to reduce rear-end collisions for those most vulnerable in traffic.”Among the U.C. Berkeley findings:
- Lane-splitting is safe if done in traffic moving at 50 mph or less, and if motorcyclists do not exceed the speed of other vehicles by more than 15 mph;
- 69 percent of lane-splitting motorcyclists were exceeding the traffic speed by 15 mph or less; speed differentials up to 15 mph were not associated with changes in the frequency of injury;
- Compared to riders who were not splitting lanes, lane-splitting motorcyclists were markedly less likely to suffer head injury (9 percent vs. 17 percent), torso injury (19 percent vs. 29 percent) or fatal injury (1.2 percent vs. 3 percent);
- Lane-splitting riders were significantly less likely to be rear-ended than non-lane-splitting riders (2.6 percent vs. 4.6 percent);
- Lane-splitting motorcyclists were more likely to be wearing a full-face helmet than other motorcyclists (81 percent vs. 67 percent);
- Compared to other motorcyclists, lane-splitting riders were more often riding on weekdays and during commuting hours, were using better helmets and were traveling at slower speeds;
- Lane-splitting riders were less likely to have been using alcohol.
