Field Operations Bureau

The Automotive Safety Enforcement Division (ASED) manages the state’s vehicle safety inspection program, including salvage inspections, safety equipment repair orders, and post-crash investigations. Our goal is to keep unsafe vehicles off of the road. ASED oversees about 1,600 inspection stations and conducts roughly 750,000 inspections each year.

This division ensures vehicles meet Maryland’s safety standards. Officers inspect vehicles, check repair shops and dealerships for compliance, and investigate auto theft and fraud.

The Crisis Negotiation Team (CNT) is a specialized unit committed to the safe resolution of emergency situations, including hostage crises. The team leverages the expertise of trained officers and appropriate resources to achieve this goal. Furthermore, the CNT offers support to other police departments when necessary.

The K-9 Unit supports the Maryland State Police and allied law enforcement agencies using specialized canine support. The dogs are trained to locate and alert officers for the following:

• Illegal drugs
• Explosives
• Missing people
• Criminal suspects

The Motorcycle Unit offers rapid and adaptable assistance throughout the state. Troopers on motorcycles respond swiftly to both traffic and criminal incidents, particularly in areas that are otherwise difficult to access.

The S.T.A.T.E. Team (SWAT) was created in 1979 providing a team of highly trained troopers as a resource to respond to high-risk incidents.

The S.T.A.T.E. Team is responsible for managing critical situations, including hostage barricade incidents, high-risk warrant services, dignitary protection, waterborne operations, and terrorism-related incidents. The team serves as a vital training and evaluation resource for the MSP Academy, in-service personnel, and allied agencies at all levels. Their expertise covers a wide range of topics, from patrol and firearms to advanced tactics like active shooter response. The team frequently collaborates with other police departments to help resolve critical incidents.

Founded in 1960, the Underwater Recovery Team (URT) is a specialized unit of sworn personnel trained in search, recovery, and underwater evidence collection. URT divers are trained to operate in challenging environments—lakes, rivers, quarries, coastal waters, and ice-covered or zero-visibility “black water.” Missions range from body and vehicle recovery to explosive identification, hull searches, and evidence collection such as weapons, human remains, or personal effects.

Notable responsibilities include:

• Recover items from underwater, sometimes in zero visibility
• Perform underwater security scans for major events
• Search for missing people and evidence
• Assist during aircraft crashes and water rescues
• Identify threats 

All team members are full-time MSP troopers with advanced dive certifications. They are on-call 24/7 and prepared to respond in any water-based emergency in Maryland and beyond. 

Launched in May 2013, this program focuses on reducing crashes caused by impaired driving in Maryland. Members of the SPIDRE Team target areas with high numbers of alcohol- and drug-related crashes to improve road safety in Maryland. The SPIDRE Team is funded by the Maryland Department of Transportation’s Highway Safety Office.

Each year, about 142 people are killed in crashes involving alcohol or drugs—nearly one-third of all traffic deaths in the state. Using crash data, a team of specially trained Maryland State Troopers focuses enforcement in high-risk areas while working with local and state partners to make arrests and prevent impaired driving.

Since inception, the SPIDRE Team has helped save lives by reducing crashes and injuries.
