Maryland Work Zone Certification Requirements
Maryland requires that workers performing flagging and temporary traffic control duties in active work zones hold appropriate certification. The Maryland Department of Transportation State Highway Administration (MDOT SHA) enforces work zone safety standards aligned with the Manual on Uniform Traffic Control Devices (MUTCD) as adopted in Maryland, which governs flagging operations, traffic control device placement, and worker protection requirements on state roads.
ATSSA Flagger Certification is widely accepted across Maryland public agencies, general contractor compliance requirements, and utility corridor projects. Contractors operating on MDOT SHA projects, county roadway programs, and municipal contracts should verify current project-specific certification requirements with the prime contractor or project documents, as requirements may vary by agency, funding source, and contract terms.
For supervisory and safety personnel, OSHA 10 and OSHA 30 certifications are commonly required on federally funded construction projects and public utility work in Maryland. The specific requirement — 10-hour or 30-hour — depends on the worker's role and the governing contract. Contractors should confirm which tier applies based on their workforce structure and applicable project specifications.
Requirements vary by agency, prime contractor, and contract documents. LADMA can help you identify appropriate certification for your workforce, but final compliance determination rests with the project specifications and governing agency.

Frequently Asked Questions — Maryland Certification Classes
Yes. ATSSA Flagger Certification is accepted on MDOT SHA projects, county road programs, and the majority of contractor-required work zones across Maryland. It is the standard credential for workers performing flagging and temporary traffic control duties in Maryland work zones. Contractors should verify with project-specific documentation that ATSSA certification meets the requirements of their particular contract or prime contractor compliance standards, as specific requirements can vary by project and agency.

Yes. LADMA provides on-site group training at contractor facilities, equipment yards, and project sites throughout Maryland. This is designed for contractors who need to certify multiple workers before mobilization or during an active project without disrupting field operations. ATSSA Flagger Certification, OSHA 10, and OSHA 30 are all available in a group training format. Bilingual instruction is available for mixed-language crews. To schedule group training, contact us at (240) 861-5050 or submit a group training request online.
Yes. LADMA offers bilingual instruction in English and Spanish for ATSSA Flagger Certification, OSHA 10-Hour Construction, and OSHA 30-Hour Construction. Bilingual delivery is available for both public class sessions and on-site group training. For contractors with mixed-language workforces, all participants receive the same curriculum and certification outcome regardless of their preferred language of instruction. Notify our training coordinator when scheduling if bilingual instruction is required.
Individual workers and contractors registering for public classes can register online through the LADMA certification registration page or by calling (240) 861-5050 to speak with our training coordinator. For group training requests — where LADMA will deliver instruction at your facility or site — submit the group training request form online or call directly. Our coordinator will confirm available dates, class format, and any additional logistics for your specific location and workforce size.
Public classes are scheduled sessions held at LADMA's Beltsville facility, open to individual workers and contractors sending small numbers of employees. Registration is on a per-person basis and follows a fixed class schedule. Contractor group training is a private, on-site delivery arranged specifically for your workforce — held at your location, scheduled around your project timeline, and scaled to your crew size. Both result in the same certification credentials. Group training is typically the more efficient option when certifying five or more workers from the same organization at the same time.
Maryland work zone regulations require that workers performing flagging operations in active work zones on public roads hold appropriate training and certification. The specific requirement depends on the road classification, project type, and governing agency. MDOT SHA projects and most county roadway contracts specify that flaggers must hold current ATSSA certification or equivalent approved training. Contractors should review their contract documents and consult with the prime contractor or project engineer to confirm the exact certification requirement for their specific project. LADMA can help identify the appropriate certification level for your workforce based on your project type.
