Opacity Test

Annual PSIP inspections are required of diesel and bus fleet owners to meet emission compliance measures. Starting in 2019, the state of California will enforce opacity tests. If your heavy-duty vehicle is traveling in the state of California, you can expect it to be ARB tested at border crossings, CHP weigh stations, fleet facilities and randomly selected locations. Steep penalties come with violations as well as the requirement for the vehicle to be repaired and retested. Don’t be caught in a fog of smog. The professional certified team at DEE is available to you 7 days week.  Following is what you can expect from a DEE opacity test:

  • The information is electronically backed up for the convenience of annual service as well as security back up.
  • Each truck receives a windshield sticker that displays compliance and can easily be seen at roadside set-ups and weigh stations.
  • Each truck is checked for the Emissions Control Label. We’ll let you know which ones are missing or illegible so that you can replace it without receiving a citation.

Meet state regulations, boost performance and do your part to clean the air with an opacity test from DEE.
