As part of the new ELDT requirements that went into effect on February 7, 2022, all drivers seeking an Oklahoma HazMat endorsement are required to complete a Hazardous Materials theory training program BEFORE testing at a local DPS office. The program must be provided by a company/entity on the official Training Provider Registry and will fulfill the necessary theory instruction needed to take the knowledge test as part of the Federal Entry-Level Driver Training (ELDT) requirements. As part of the ELDT requirements, this training is now required before taking the written test for the HazMat endorsement at the Oklahoma DPS.
