Delaware emissions testDelaware: DMV emissions inspection
Will your car pass Delaware's emissions test? For cars from 1996 on, the station plugs into your car and reads the same things Athena OBD reads, so you can know before you go.
Where
statewide (Kent, New Castle under Reg 1131; Sussex under Reg 1126)
Which cars
1968+ (plug-in test for 1996+); newest 7 model years exempt
What it takes to pass
- The check engine light must work and be off, with no fault stored that turns it on.
- Cars from 2001 on: one of the car's self-tests may be unfinished.
- Cars from 1996 to 2000: up to 2 of the car's self-tests may be unfinished.
- Just reset the codes or changed the battery? The self-tests start over: drive normally for a few days, in town and on the highway, before you go.
Check your car's year
A guide, not a guarantee: stations also check things Athena OBD can't (the gas cap, paperwork), and rules change. Checked against Delaware's sources in October 2026.
Drive a BMW?
Athena OBD reads the engine codes every car shares. Our sister app, AutoLingo for BMW, goes much further on a BMW: the airbags, ABS, instrument cluster and body modules too, plus service resets, even on older E-chassis cars.
