Combination Vehicle Types

Combination vehicles are defined as any vehicle that consists of two or more vehicles connected together, such as a tractor-trailer or a double/triple trailer. There are different types of combination vehicles covered by the CDL permit, each with its own specific requirements.

• Tractor-Trailers:A tractor-trailer is a combination vehicle that consists of a truck or tractor that pulls a semi-trailer or full trailer behind it. The semi-trailer or full trailer can be loaded with various types of cargo, such as dry goods, refrigerated goods, or hazardous materials.

• Double/Triple Trailers:Double/triple trailers are combination vehicles that consist of two or three trailers connected together. The first trailer is attached to the truck or tractor, and the additional trailers are connected to the first trailer. Double/triple trailers are often used to transport large volumes of cargo, such as agricultural products or construction materials.

• Tank Vehicles:Tank vehicles are combination vehicles that consist of a truck or tractor that pulls a tanker trailer behind it. The tanker trailer is designed to transport liquid or gaseous cargo, such as fuel, chemicals, or food products. Tank vehicles must meet specific safety regulations to ensure the safe transportation of hazardous materials.

Combination Vehicle Maneuvers

Operating combination vehicles requires drivers to master specific maneuvers, such as backing, turning, and parking. These maneuvers can be challenging due to the length and weight of the vehicle.

• Backing:Backing a combination vehicle requires drivers to use the trailer’s wheels to guide the vehicle in reverse. Drivers must be aware of the trailer’s swing and avoid obstacles while backing up.
• Turning:Turning a combination vehicle requires drivers to make wide turns to avoid jackknifing. Drivers must also be aware of the trailer’s tracking and avoid cutting corners too sharply.
• Parking:Parking a combination vehicle requires drivers to find a large enough space to accommodate the length of the vehicle. Drivers must also be aware of the trailer’s overhang and avoid hitting objects when parking.

To safely perform these maneuvers, drivers should practice regularly and use proper techniques, such as using spotters, setting up wide turns, and checking mirrors frequently.

Combination Vehicle Safety Regulations

Combination vehicles are subject to federal and state regulations to ensure their safe operation. These regulations cover various aspects, including weight limits, load securement, and hours of service.

• Weight Limits:Combination vehicles are subject to weight limits to prevent damage to roads and bridges. The weight limits vary depending on the number of axles and the type of cargo being transported.
• Load Securement:Cargo on combination vehicles must be properly secured to prevent it from shifting or falling off during transit. Drivers must use proper tie-downs and other securement devices to ensure the safety of other road users.
• Hours of Service:Drivers of combination vehicles are subject to hours of service regulations to prevent fatigue and ensure their alertness while driving. These regulations limit the number of hours that drivers can drive in a day or a week.

Violating these regulations can result in fines, penalties, and even disqualification from driving. Drivers must be aware of these regulations and comply with them to ensure the safety of themselves and others on the road.
