How It Works

Three steps. Zero surprises.

No paperwork to fill out ahead of time, no online queue to join. Just pull in.

Step 01

Drive in

Pull into any open bay — no appointment, no forms. A technician greets you before you've put it in park.

Step 02

Get tested

Our STAR-certified equipment runs the full emissions check while you wait in a clean, comfortable lounge.

Step 03

Get your certificate

We e-file straight to the DMV and hand you a printed copy — registration-ready, no extra trip required.

Precision Equipment

Calibrated daily.
Trusted by the state.

Every analyzer in our bays is calibrated to STAR-station standard and cross-checked against DMV reference gas each morning before the first car rolls in. What you see on screen is exactly what gets filed.

  • OBD-II & tailpipe testing, dual-certified equipment
  • Live results on-screen — no black box, no guessing
  • Direct DMV e-file the moment you pass
