Safety Equipment Repair Order (SERO)

A Maryland State Trooper or other law enforcement officer in Maryland may issue a Safety Equipment Repair Order (SERO) to the operator of a vehicle that is observed to be defective according to Maryland vehicle safety standards  Appendix A lists the types of defects for which a SERO can be issued.  

The SERO requires the vehicle owner to have the defect(s) cited repaired within 10 days, and a certification of the repair to be submitted to the Automotive Safety Enforcement Division (ASED) within 30 days. An SERO can be issued for defective safety equipment on all classes of Maryland registered motor vehicles, trailers, and semi-trailers ( Exceptions; Interchangeable registration, Historic registration under 10,000 lbs. GVWR 1985 and older and Street Rod, Paper Temporay Registration).

 

How do I resolve a Safety Equipment Repair Order (SERO)?

To resolve an SERO issued for your vehicle, you must have the vehicle repaired within ten (10) days. The repairs may be made at any repair shop of your choice, or you may do it yourself.

After the vehicle is repaired, you will need to take the SERO to an Maryland authorized inspection station in order to have the repair inspected and certified. The registered inspector will sign and stamp all copies of the SERO to certify that all defects have been fixed correctly.  If the inspection for certification of the SERO requires jacking, lifting, measuring, or testing the vehicle, the inspection station may charge a prorated fee based on their hourly labor rate.
 

If all of the defects identified on the SERO are followed by an asterisk (*), indicating that the repair can be visually inspected, it can be inspected free of charge at an authorized inspection station, by a Maryland State Police Trooper or local police officer in a participating police department. The trooper or officer must inspect your vehicle during daylight hours, while the weather is not inclement. However, be sure that all of the defects identified on your SERO have an asterisk.
 
When the repair has been certified and the SERO has been signed and stamped, you must submit Copy 5 (buff card stock) of the SERO, or the right half of an electronically generated SERO to the ASED  by hand delivery or by mail to;
Maryland State Police
Automotive Safety Enforcement Division (ASED)
6601 Ritchie Highway, Rm122
Glen Burnie, MD 21062
You should retain Copy 4 (goldenrod) of the SERO for your records or if an electronically generated SERO retain the left half of the SERO.

What happens if I don’t return the signed copy of my SERO within 30 days?

If the Maryland State Police ASED does not receive the signed Copy 5 of your SERO within 30 days after the date that the SERO was issued, you will receive a notice that your vehicle registration will be suspended.

 

The suspension will take place five (5) days after the notice of suspension is mailed. When your vehicle registration is suspended you cannot:

  • Legally drive the vehicle; or
  • Renew the vehicle's license plates.

If your vehicle's registration is suspended, you must immediately return the license plates to an MVA branch office. If you do not return the license plates within 10 days after the date on which the suspension notice was mailed, a tag pick up order will be issued. The license plates then will be subject to immediate confiscation by a police officer.

What should I do if I got rid of my vehicle after the SERO was issued?

If your vehicle has been traded, sold, repossessed, junked or otherwise disposed of, you must submit a document that indicates the vehicle’s disposition and includes the vehicle identification number (VIN), make, model, title number, and the date of the disposition. The document should be attached to Copy 5 of the SERO when it is submitted to the ASED. The type of documentation required depends upon the vehicle’s disposition:

  • Traded – submit a copy of the contract with the dealer who accepted the vehicle as trade-in.
  • Sold – submit a notarized statement signed by you.
  • Repossessed – submit a statement on the letterhead of the company that repossessed the vehicle (usually a financial institution).
  • Junked – submit a statement on the letterhead of the automotive dismantler or recycler who received the vehicle.
  • Otherwise disposed of – submit a notarized statement signed by you.

What should I do if I lost my SERO and need a duplicate?

If you lose your SERO, you may contact the MSP Automotive Safety Enforcement Division or your local MSP barracks weekdays (excluding state holidays) between 8:30 a.m. and 4:30 p.m., and ask about obtaining a copy.

Fees:

The vehicle owner must pay for the repairs needed to correct the vehicle defect(s). If the defect is a visual defect, noted with an asterisk (*) beside the defect number, there is no fee for the certification.  If the inspection for certification of the SERO requires jacking, lifting, measuring, or testing the vehicle, the inspection station may charge a prorated fee based on their hourly labor rate.
