Motor Vehicle Safety Inspection Station Permit

This is optional business the shop opts into, not a condition of repairing vehicles at all — a repair shop needs no state license simply to fix cars. Becoming an official inspection station is a different, separate choice: $10 a year covers a safety-only permit, and an emissions permit adds $100 more where it applies, for $110 combined. The individual performing inspections needs a further inspector or mechanic permit, which costs nothing and lasts three years. What the station may charge the motorist is capped by the same statute — no more than $12 for a passenger vehicle or truck and no more than $10 for a motorcycle or trailer, with no extra charge for a follow-up inspection within twenty business days once a defect has been fixed.
