One guy, one service truck, straight answers

I'm Matthew. Clean Truck Smog is owner-operated — when you call, you get me, not a call center. I run one service truck loaded with the scan gear and the calibrated opacity meter, and I drive it to wherever your rig sits.

I started this because drivers were losing half a day and a load of money sitting at a shop for a 20-minute test. That's backwards. So I come to the yard, the shop, the jobsite or the driveway, run the test, file the result, and get you back to work.

You get an honest diagnosis. If your truck fails, I'll show you what triggered it and what it actually takes to pass — no upselling parts you don't need. Fix it and retest with me within 30 days and the retest is free. And I keep track of your compliance dates, so you get a reminder about six months out instead of a CARB notice.

Early mornings and Saturdays are normal here. Call or text me at (909) 495-4548 — Mon–Sat, 7am – 7pm.
