A mild winter might have lulled some drivers, but those Washington State mountain conditions are still icy. Don't risk a $137 fine with your studded tires.
I know it's tempting you windshield is covered in ice and it is freezzzing outside so I think I'll just start my car go back inside finish my coffee and when I return my car with be thawed and ready....NOT SO FAST...it is actually illegal to leave your vehicle running and unattended...with one exception
