Drive a Clean Machine Program:
Repair and Replacement Assistance

The AirCheck Texas Drive a Clean Machine is a program to remove older, more polluting vehicles from Texas roadways in emissions counties. If you qualify you could receive up to $3500 towards replacing your vehicle or up to $600 in repair assistance. Motorist applying for REPAIR ASSISTANCE should obtain a repair voucher prior to having emission related repairs performed, as repairs made prior to approval will not be eligible for reimbursement.

ONLY Recognized Emission Repair Facilities (RERF) can accept vouchers and perform voucher repairs through the repair assistance program.   Participating RERF’s are identified on our (RERF) locator with a Gold Star.
