It’s Illegal to Warm Up Your Car in the Mid Columbia
Pasco PD and Kennewick PD have been issuing weekly warnings not to, but it's actually ILLEGAL to warm up your car unattended -- that's true in all of Washington state.
According to the Washington State Code, it's illegal to leave your car unattended without first stopping the engine.
Besides the REAL threat of theft, what if the car were to start rolling and you're not in it? You'd be liable for all property damage and injuries your two-ton metal beast can cause when you're not around.
Depending on the potential damage your car could cause, you could liable for anything from a gross misdemeanor to a Class C felony.
