Q: As someone who recently moved to Washington, I was surprised that there are no safety inspections. Wouldn’t we all be safer if all the cars on the road had properly operating lights and regulation equipment? Why are there no safety inspections as in other states?
A: Yes, vehicle inspections increase safety, but we can’t tell you how much. That was the conclusion of a study by the US Government Accountability Office. It’s hard to know if we should or shouldn’t do something when we don’t know how much it helps.
I can’t say for sure why Washington doesn’t have safety inspections, but I can explain why more states used to have them than do now. Money. The federal government used to withhold a percentage of highway funds from states without vehicle inspections. At the peak, 31 states had vehicle safety inspections. Washington was not one of them. In 1976 that rule changed, and now there are 16 states with annual or biannual inspections. States that still have inspections point out that they make their roads safer. States that have eliminated them say that the cost doesn’t justify the small (or possibly non-existent) increase in safety. States without inspections don’t seem to have more fatal crashes than those that do. Washington has a lower traffic fatality rate than ten of the 16 states with safety inspections.
