Vagal Nerve Stimulation. Vagal nerve stimulation is a treatment used to reduce the frequency and intensity of seizures when medications aren't effective. The vagus nerve is one of many nerves that carry messages to and from the brain. It helps regulate internal organs such as the heart and stomach. Nerve fibers within the vagus nerve are connected to the part of the brain believed to be responsible for producing seizures.
A Class B CDL holder, on the other hand, is only allowed to drive a commercial motor vehicle towing a trailer that is less than 10,000 pounds. This means that a Class A CDL holder can drive all vehicles including Class B ones while a Class B CDL holder can drive all vehicles except Class A ones.
The federal standard requires states to issue a CDL to drivers according to license classifications. Class A License - Any combination of vehicles with a GVWR of 26,001 or more pounds provided the GVWR of the vehicle(s) being towed is in excess of 10,000 pounds. Class B License - Any single vehicle with a GVWR of 26,001 or more pounds, or any such vehicle towing a vehicle not in excess of 10,000 pounds GVWR.
