Using endorsements, you can go for different driving jobs including long-haul trucking, passenger transport, HazMat transport, and many more. Drivers with endorsements are also more likely to earn higher income because of their specialized skills. There are many industries like fuel transport, passenger services, and bulk liquid hauling that are sure to stay in demand in the future making endorsements relevant for the future also.
