Although numerous studies by the RCMP and Transport Canada show that at least 90 per cent of British Columbians wear their seatbelts, a Coroners Service study showed that fewer than 60 per cent of those who died were wearing them at the time they crashed.
The BC Coroner’s Service study looked in detail at fatal motor vehicle crashes for 2010 in the Interior Region of BC, a total of 85 deaths. (Crashes involving motorcycles, cyclists or pedestrians were not included.) Of the 85 cases, only 47 per cent were wearing seatbelts at the time of the crash, 41 per cent were definitely not, and seatbelt usage was unknown in 12 per cent of the cases.
