MD State Police Launch Diesel Emission Inspection Team

MD State Police Launch Diesel Emission Inspection Team.

Recently the MD State Police Commercial Vehicle Enforcement Division conducted a diesel emissions certification course in preparation to deploy roving crews to enforce the state’s diesel emissions law.

When a Maryland registered diesel vehicle fails a roadside smoke emissions test the driver will be issued a Diesel Emissions Safety Equipment Repair Order. 

Owners must have that vehicle repaired and retested within 30 days or face having that vehicle's registration suspended.  More about Maryland’s Diesel Vehicle Emissions Control Program is at https://mde.maryland.gov/programs/Air/MobileSources/Documents/Diesel_Brochure.pdf.
