What endorsement do i need to drive semi-truck?

To drive a semi-truck, you typically need a Commercial Driver's License (CDL) with the appropriate endorsements. The most common endorsement for operating a semi-truck is the "Class A" CDL, which allows you to drive a combination of vehicles with a gross vehicle weight rating (GVWR) of over 26,001 pounds. Depending on the cargo you plan to transport, you may also need additional endorsements, such as HazMat for hazardous materials or Tanker for tank vehicles. Always check your state’s specific requirements, as they can vary.
