Next someone will ask how to turn the fuel up lolGeez, not this again
How do you turn the fuel up?? I've never figured it out!!Next someone will ask how to turn the fuel up lol
He mentioned it was a "900 series" (M939) truck. They are 100% air brakes any way you look at it. Any of the older 5-tons would be hyd brakes with air-assist. I don't think you'd need a air brake endorsement on a older 5-ton.Maybe we should define "air brakes"?
I will argue that MVs don't have "air over hyd" brakes. In true air over hyd brakes, when you loose air pressure you loose 100% of your brakes. A military vehicle is really no different than 99% of passenger cars out on the road. The only difference is they use air pressure to boost the brakes instead of vacuum.The MD CDL booklet, Section 1.1.1, states "you will be required to take the air brake knowledge test if your vehicle has air brakes, even air over hydraulic brakes".
And DoT uses this definition. Some states, and Canada, actually have a definition of an "air boosted hydraulic braking system" that are NOT air brakes.I will argue that MVs don't have "air over hyd" brakes. In true air over hyd brakes, when you loose air pressure you loose 100% of your brakes. A military vehicle is really no different than 99% of passenger cars out on the road. The only difference is they use air pressure to boost the brakes instead of vacuum.
In a true air over hyd system there is no mechanical linkage from the pedal to the master cylinder. MVs have air-assisted hyd brakes.
I've got a Class A CDL so all this discussion really has no bearing on me personally. It's not a bad idea to go ahead and get your CDL even if it's not required. I've had mine since I was 18.
It is an easy test. It takes a little time and a few dollars. Just get a CDL. But if you have a problem where you insist on driving after having a few drinks, be advised, if you are stopped with a .04 BAL, you will lose ALL your driving privileges
State regs may have changed but not federal regs. There is no such yearly medical card requirement in TN. You are required in TN to maintain a medical card with a CDL and will be checked if stopped by LEO or when you go to renew your DL.Personally I have a Class B CDL and I Recieved a Letter from my State DMV saying that Federal Regulations had changed and I now have to Supply Proof to my State DMV everty Year, that I have a DOT Medical Card for my CDL or the State will Pull my CDL and the will give me a Normal Drivers Licence in place of my CDL. This means, that you will need to get a D.O.T. Physical every one or two Years depending on your Health to keep your CDL. Factor in the Cost and Time spent getting your Physical into the Equation for getting and keeping a CDL. Also, in order to get your CDL, you will need to have a Truck that is Applicable to the Type of CDL you are getting to Test in.
