A tanker driver is a transportation specialist who is in charge of transporting liquids and gases in a tanker truck over the road. Tanker drivers must keep excellent records, conduct safety checks, load and unload whatever material they are hauling, and uphold all safety practices and standards at all times. Tanker drivers may travel short distances making multiple deliveries, like many gasoline and propane transport divers. Others haul long distances to deliver their cargo, which may require them to be on the road for many nights.
