The Federal Motor Carrier Safety Administration has issued a final rule that allows states to waive the hazardous materials endorsement requirement for holders of Class A commercial driver’s licenses who transport no more than 1,000 gallons of aviation grade jet fuel in support of seasonal agricultural aircraft operations. The new rule becomes effective March 10, 2026.

The FMCSA said many farm operations rely on aircraft to apply pesticides or fertilizers to their crops. Agricultural aviation companies often deliver aircraft fuel to staging areas some distance from their headquarters. These companies, particularly in remote, rural areas have difficulty finding CDL holders with hazmat endorsements to complete these deliveries.

The agency had previously allowed states to waive the hazmat endorsement requirement for employees of four specific agriculture-related businesses: custom harvesters, farm retail outlets and suppliers, agrichemical businesses, and livestock feeders. This final rule gives states authority to waive the hazmat endorsement requirement in an additional category for Class A CDL holders who transport up to 1,000 gallons of aviation grade jet fuel (often called Jet A) in the CDL holder’s state of domicile (or in another state that has adopted the waiver) and in support of agricultural aircraft operations.
