Maryland Governor Wes Moore declared a state of emergency intended to lower transportation pressure on agricultural and forestry operators during the 2026 harvest season. The order remains in effect for 30 days and may be renewed, but the governor's office said the emergency period will not extend beyond December 31 unless otherwise ordered.

Under the order, qualifying vehicles carrying agricultural or forestry products or supplies may use dyed diesel on public roads without state penalties. Drivers do not need to register, but they must be able to document an eligible load if asked. The state also waived fees for 30-day Exceptional Hauling Permits so qualifying haulers can carry heavier loads within existing limits.

The relief is limited. Federal taxes, penalties, and restrictions are not waived, and producers remain responsible for federal compliance. Existing safety rules, bridge restrictions, and weight limits remain in force, and the order excludes interstate highways, local roads, and Maryland Transportation Authority roads.

Reuters reported that U.S. diesel prices remained near record highs on October 9 amid tight global supplies. The Maryland Department of Agriculture will coordinate state implementation and monitor the order's effectiveness.
