Vehicle Inspection

DEQ does not require emissions testing of newer model year vehicles because they typically have lower mileage and are therefore less likely to experience problems with their emissions control systems.

During calendar year 2018, the following model years qualify as a “Newer Model Year Vehicle”

  • Model Year 2015 (So long as the current registration expires before January 1, 2019)
  • Model Year 2016
  • Model Year 2017
  • Model Year 2018
  • Model Year 2019

DMV’s vehicle registration renewal

If you have a “Newer Model Year Vehicle” as described above, then you can renew online at without going through DEQ. If this doesn’t apply to your vehicle or you don’t want to renew online, then follow the INSTRUCTIONS section on DMV’s renewal application form.
