What type of Class C licence, exactly? A basic drivers licence in California is known as a Non-Commercial licence, or Class C licence. HOWEVER, there is a Class C Commercial Drivers Licence, intended for vehicles under 26,000 lbs. GVWR which are placarded to haul hazardous materials, designed to transport more than 15 persons (including the driver), etc. If it requires the non-commercial licence, there's no requirement to possess a medical card. If it requires the Class C Commercial Drivers Licence, then, under federal law, you must always have a valid DOT medical card in your possession at all times when operating that vehicle.
If the commercial vehicle requires a CDL to drive it, you do.
Yes
You're required to have a current medical card on your person at all time when you're driving a vehicle which requires a CDL. In any state. That's federal law.
No However, if your job requires you to operate a vehicle for commercial purposes which has a Gross Vehicle Weight Rating in excess of 10,000 lbs., you'll be required to get one.
The best option for commercial vehicle security is vehicle alarms. You can also install a decive that requires a special key or chip to start the vehicle in addition to the ignition key.
Depends on the vehicle itself. Any vehicle used for commercial purposes is a commercial vehicle. Vehicles requiring a Commercial Drivers License (CDL) are defined as a Commercial Motor Vehicle (CMV) by the Federal Motor Carrier Safety Administration, but commercial vehicles can be of a lower GVWR than a CMV. Anyone driving a commercial vehicles over 10,000 lbs. GVWR is supposed to possess and retain a DOT medical card, and any commercial vehicle over 26,000 lbs. GVWR requires a CDL, as well as any vehicle of any GVWR which is a bus designed to transport more than 15 persons (including the driver) or is carrying a quantity of hazardous materials which requires hazmat placards to be displayed.
A person who operates a vehicle which requires the operator to possess a Commercial Drivers Licence.
A commercial vehicle such as a truck or limo needs to have a very high coverage cost because they are used for commercial purposes. The most common insurance for them is comprehensive insurance.
Yes. Having said that, if your commercial vehicle is a combination vehicle, the front plate goes on the tractor and the back plate on the trailer; the tractor won't have a back plate.
Mud flaps have to be on medium and heavy duty trucks in Pennsylvania. This is the law and you can be fined if they aren't.
No. A vehicle is commercial in nature based on its usage. More the same with classifying it as a Commercial Motor Vehicle (CMV), which requires an FHWA annual inspection sticker, registration as such, and DOT medical cards if used in interstate operations. Stack size does nothing to change the manner of use or Gross Vehicle Weight Rating of the vehicle.
I'm not sure about PA, but in California, if the tires protrude outside the body of the vehicle then mudflaps are required.
