WASHINGTON (AP) — Direct costs from deaths and injuries due to motorcycle crashes were $16 billion in 2010, but the full cost is likely higher because long-term medical expenses are difficult to measure, a government report said.

Motorcyclists are involved in fatal crashes at higher rates than drivers of other types of vehicles, and are 30 times more likely to die in a traffic crash than passenger car occupants, according to the Government Accountability Office report.
