Short answer
Even in the program counties, these are not tested: electric vehicles, diesel vehicles, motorcycles and mopeds (TCEQ); vehicles outside the 2 through 24 year window; vehicles registered as antiques (DPS); and, per TxDMV, classic cars.
By type
Not required to inspect: electric vehicles, diesel vehicles, motorcycles, and mopeds.
Vehicles exempt from emissions inspections, including electric-only vehicles, continue to be exempt.
Vehicles statutorily exempt from emissions inspections, including electric vehicles and classic cars, will remain exempt.
By age
By registration
Vehicles registered as “Antiques” are exempt from annual inspection.
Outside the 18 program counties nothing is tested. DPS also lists exceptions for vehicles registered in a program county but kept elsewhere: see registered in an emissions county but living elsewhere.
Not an exemption: a waiver
A vehicle that fails and cannot reasonably be fixed may get a waiver or time extension. That is decided case by case by DPS; see emissions waivers.
The following waivers and extensions are issued by the Texas Department of Public Safety (DPS).

Hybrids are not on TCEQ’s list of vehicles not required to test; see electric and hybrid cars. Exempt from the test does not mean exempt from fees: most non-commercial vehicles, electric cars and diesels included, pay the $7.50 inspection program replacement fee at registration. Vehicles with antique, custom vehicle or street rod plates are among those the law excludes from that fee; see the replacement fee.
Motor homes in EMISSIONS counties are also required to have the appropriate emissions test performed.
Inspection Replacement Fee $7.50
