If you are paid by a percentage of the line haul, then hazmat definitely pays more. In the oil field hazmat typically pays 20-25% more than regular freight. When you go in to get fingerprinted for hazmat, also get fingerprinted for TWIC. There's a fee for each of them. Most companies reimburse you for those costs.
Doesnt pay much if any more, If your hauling for a freight company and doing the occasional hazmat load. If your hauling for a company who does mostly or only hazmat. It pays much better.
I've had hazmat and all endorsements since this class system,and hazmat started. Everytime you renew your cdl license,you have to take the hazmat test again. At least here in Md. Test wasn't all that hard when it started,but tougher now. Study,or you'll fail it.
Hazmat pays. Magnum will pay you one cent more per mile for all your miles just because you have hazmat. They pay 5 cents a mile for hazmat loads. You'd be surprised. Cola concentrate is a hazmat load. I've also picked up cola concentrate in Pa. Along with small amount of cleaner that was flammable. Plackard not required for flammable. Small enough amount. No problem with tunnels on I70 PA. It depends on what your hazmat load is. The cola was (if I remember right) corrosive. Not a problem in the tunnels. The shipper made sure of all of this. Follow their directions. Their written directions with the hazmat.
KLLM recently bought a company called Ecoshield. I dont know much about the company yet except they handle mostly Hazmat loads. So far they only hire owner operators but thats supposed change soon. It was a company with about 50 drivers but it will probably grow now that KLLM can put all their money behind it. FFE terminal in Lancaster is littered with Ecoshield trailers and no there is no place to park half the time. We parking in the Isles and along the sides blocking off empty trailers. Its annoying because so many KLLM trucks, and they have a HUGE terminal in Jackson that FFE doesn't use at all. Our terminal is small by comparison.
Some companies require hazmat just to keep the riff raff out. Saves them a little money on background checks
HazMat pays more IF YOU WORKFOR A GOOD COMPANY. Just adding HazMat to your CDL may not boost your pay. DON'T WORK FOR CRST, CR ENGLAND, WESTERN EXPRESS.
LTL and Tanker are known to be one of the best paying and work life BALANCE jobs. So yes Hazmat pays more. Only jobs like UPS parcel and Walmart pay well without hazmat that has a lot of hometime or home daily even.
