Smog Check and Car Inspection in Delaware
The Division of Motor Vehicles (DMV) requires vehicles registered in the state to undergo regular safety inspections and emissions testing. DE vehicle inspections consist of two parts, which will be done at the same time when you appear:
- The vehicle safety inspection ensures that your vehicle is not a danger to yourself and other drivers on the road.
- The vehicle smog check and emissions test ensures that your vehicle's exhaust system works effectively.
DE Inspection Requirements & Exemptions
You must pass a Division of Motor Vehicles (DMV) emissions test and safety inspection if:
- You want to register your car for the first time in the state (must be completed within 60 days of establishing residency.
- You need to renew your registration (may be completed up to 90 days before your registration expires).
- You are ordered to submit your vehicle for inspection by law enforcement (must be completed within 5 days or risk having your registration suspended).

You do not have to complete a safety or emissions inspection if the vehicle meets all of the requirements below:

Even if your vehicle meets these requirements, you can be ordered by law enforcement to submit your vehicle for a safety inspection if it's deemed necessary.

Out-of-State Vehicle Inspection
If you are not in Delaware at the time of your vehicle inspection deadline, or your vehicle is out of state, you may apply for an Out-of-State Inspection Packet to complete the inspection requirements. You and/or your vehicle must be more than 250 miles from a DE DMV inspection station to be sent a packet.
If your vehicle is more than 250 miles from a DE DMV inspection station, and you will not be able to return it to the state before your registration expires, then you must contact the DMV to request an Out-of-State Inspection Packet.
The Out-of-State Inspection Packet contains completion requirements for both the safety and emissions inspections, including the Application for Out-of-State Inspection of a Delaware Registered Vehicle (Form MV210).
- Take the packet and your vehicle to a local dealership or mechanic.
- The person evaluating your vehicle must validate that it meets the requirements outlined in the packet.
- Make a copy of your current DE driver's license and proof of insurance.
- Include payment for your registration renewal fees.
- Include a self-addressed envelope with your current out-of-state address.

- Division of Motor Vehicles
- Correspondence Section
- P.O. Box 698
- Dover, DE 19903
If you are out of state when you need to complete a DE DMV vehicle inspection but your vehicle is in state, a friend or family member may take the vehicle to be inspected for you.
They will need:
- Your vehicle's current DE vehicle registration card.
- Proof that your vehicle is insured.
DE Testing Fees
There is no charge for the vehicle inspection or for having your vehicle retested.
You will have to pay a $20 late fee plus your standard renewal fees if you fail to complete your inspection before your vehicle's registration renewal deadline.
DE Vehicle Inspection Failure
If your vehicle fails the safety or emissions testing for any reason, you will need to get repairs done to your vehicle and have it retested. You will receive your inspection sticker once the problems are fixed and the vehicle passes the tests.
Safety Inspection Failure
The Delaware DMV does not provide any waivers for failing the safety inspection. If your vehicle fails the safety test, you will not be able to register it or renew its registration until you fix whatever issues resulted in failure (e.g. new windshield, tires, brake lights, etc.).
The report given to you at the end of the inspection will indicate what you need to have corrected. You will have to reappear at a DMV testing station after fixing the problems.
Emissions Testing Failure
If you fail an emissions test and your registration is about to expire, you may be eligible to apply for a temporary registration tag from the DE DMV while your car is repaired. A temporary tag costs $20.
Common reasons for failing an emissions test are:
- Dirty air filter.
- Defective catalytic converter.
- Defective ignition.
- Defective spark plug(s) or spark plug wire.
- Improper ignition timing.
- Leaky vacuum.
Your vehicle inspection report will list the reasons your vehicle failed, and you will not be allowed to register or renew your vehicle until you make the necessary repairs and successfully pass a retest.
Delaware Temporary Tags
If you need to complete repairs on your vehicle but your registration is about to expire, you may be able to apply for a 30-day temporary tag from the Division of Motor Vehicles (DMV). This will allow you to continue to drive while you get your vehicle repaired and retested.
Temporary tags will not be issued for vehicles classified as smoking excessively or as safety hazards. The decision to issue a temporary tag is entirely up to the DMV.
To apply, you must:
- Go to your local DE DMV.
- Present your vehicle inspection report.
- Present your vehicle registration card or title.
- Present your driver's license.
- Pay a $20 fee.
Delaware Emissions Waiver
If you have failed to pass the emissions test, you may be able to get an emissions waiver.
To be eligible, you must meet ALL of the following requirements:
- Your vehicle has failed the exhaust (tail pipe) emissions test 2 times or more.
- Your engine parameters meet the specifications set by the manufacturer.
- The cost of your repairs meets the required amount:
― $75 for vehicle models 1968―1980.
― $978 for vehicle models 1981 and newer in Kent or Newcastle County.
― $200 for vehicle models 1981 and newer in Sussex County.
- Your vehicle has all emissions control equipment.
- Visible smoke was not the reason for your vehicle's failure.
- You are able to provide all repair receipts and your vehicle inspection report.
- The vehicle did not have a fuel systems failure.
- There is no safety failure.
DE Vehicle Inspection Retesting
Once you have completed the necessary repairs on your vehicle and you're ready to have it retested―be it for safety, emissions, or both―you must return to a DMV inspection facility and be ready to present:
- Your inspection report.
- Receipts for the repairs you had done.
- A Vehicle Emissions Repair Report Form (Form MV-705) required for residents of New Castle County and Kent County.
There is no charge for having to retake the test, and if your vehicle fails the emissions test again, you may be eligible to apply for a waiver.
