If the towed vehicle is heavier than 10,000 pounds, a Class A commercial driver's license is necessary to operate any combination of vehicles with a gross combined weight rating (GVWR) of 26,001 or more pounds. You can drive the following vehicles with a Class A CDL and the appropriate endorsements:
Step 1: Call the Department of Motor Vehicles first (DMV).
Step 2: Schedule a CDL driver's exam for a Class A vehicle.
Step 3: Find out what items you'll need from the department. You may need a statement from your employer saying that you are eligible to take the test, there may be costs to pay, and in certain areas, a second written exam is necessary.
Step 4: Review any relevant materials and get advice from other drivers on how to make turns and execute particular actions when driving a class A CDL truck. Take your driving test at the DMV (s). You may be required to provide your own tractor trailer, or they may offer one for you. Make certain you inquire about this.
A lowboy is a semi-truck having two deck height drops: one after the gooseneck and another before the wheels. In comparison to other trailers, this permits the deck to be incredibly low. It can transport legal loads up to 12 feet (3.66 meters) tall, whereas other trailers can't. Lowboys are used to transport big machinery like bulldozers and huge industrial machinery.
The lowboy trailer comes in several types, for a wide range of tasks. Some types are:
The fixed gooseneck (FGN) provides for a larger deck length while still being the lightest. These trailers are lower than conventional, have low-profile tires, and commonly have drop ramps at the back to make loading equipment easier, but they are not termed "lowboys." The neck is arched in such a way that when it is lowered, it acts as a ramp, allowing equipment's front tires to be dragged onto the deck.
Fixed-neck: the neck is permanently attached to trailers; it is the lightest option, but it limits the ability to remove and load over the front.
Hydraulic detachable gooseneck (hydraulic RGN or HRGN): lightest and quickest to detach, but at the cost of weight and deck length. The gooseneck is detachable utilizing big hydraulic cylinders to raise and lower the trailer, and a tiny cylinder connects the neck to the truck, allowing a large piece of equipment to be pushed over the front into the trailer's deck for transfer. The hydraulics can be powered by the truck's auxiliary or a pony motor put in the trailer's neck.
Mechanically detachable gooseneck (mechanical RGN or MRGN): While mechanically detachable goosenecks are often lighter than hydraulically detachable goosenecks, users trade convenience and speed of detachment. Long speciality hauls are handled using this truck.
The deck of a mechanical folding gooseneck (MFGN) lowers down to ground level to create a ramp for trailer loading.
Anyone interested in driving a lowboy must have a CDL A and, depending on the state, a doubles/triples endorsement. Even with these endorsements, due to the increased complexity of running a Lowboy truck, employers are more inclined to pick their more experienced drivers. Before operating a Lowboy, most businesses would need drivers to have at least two years of CDL A experience.
