If the Federal Motor Carrier Safety Administration determines that you pose an imminent hazard, DMV will impose an emergency disqualification of your commercial driver license or commercial learner permit for up to one year. They define imminent hazard as "the existence of a condition that presents a substantial likelihood that death, serious illness, severe personal injury, or a substantial endangerment to health, property, or the environment may occur before the reasonably foreseeable completion date of a formal proceeding begun to lessen the risk of that death, illness, injury or endangerment."
