Main and long-term cost of traffic crashes is a burden on the health care system.
During 2010 in Canada in traffic crashes:
More than 123,141 injuries (11,226 serious)
More than 2,227 people were killed
Over 75 billion dollars in medical bills, rehabilitation and lost wages
About 13% of people killed in traffic collisions were pedestrians
Alcohol is a factor in approximately 40% of all fatal vehicle crashes
The first step to make a positive difference in health care costs would be to to decide to never drink and drive. Also, to avoid becoming involved in influencing others to do otherwise.
Secondly, use all protective devices while driving and make sure your passengers do also.
