The specific design and features of the tank truck are tailored to the properties of the cargo being transported and the regulations governing its movement.

Tanker trailers are specialized vehicles that can efficiently transport a variety of liquids and gases over long distances. These specialized trailers are designed to transport large quantities of liquids, including gasoline, hazardous chemicals, and even drinking water and milk.

Usually we divide tank trailers into several types
Tanker trailers are generally classified into several types based on the type of cargo they are designed to transport. Here are the main classifications:

Petroleum/Fuel Tank Trailers: Designed for transporting gasoline, diesel, jet fuel, and other petroleum products. They often have multiple compartments for different grades of fuel.
Chemical Tank Trailers: Built with materials (like stainless steel or specialized alloys) and safety features to transport various liquid chemicals, which can be hazardous, corrosive, or flammable.
Dry Bulk Tank Trailers (Pneumatic Trailers): Used for transporting dry, flowable materials like cement, sand, grain, plastic pellets, and powders. They typically use air pressure to load and unload the cargo.
Food-Grade Tank Trailers: Constructed from materials like stainless steel to ensure hygiene and are used for transporting liquid food products such as milk, juice, edible oils, and syrups.
Asphalt/Bitumen Tank Trailers: Specifically designed with insulation and often heating systems to maintain the high temperature required for transporting asphalt and bitumen.
Cryogenic Tank Trailers: Engineered to transport liquefied gases at extremely low temperatures, such as liquid nitrogen, liquid oxygen, and LNG (Liquefied Natural Gas).
Water and Non-Hazardous Liquid Tank Trailers: Used for transporting water, liquid fertilizers, and other non-hazardous liquids.
These are the primary categories, and within each category, there can be further variations in design, capacity, and features depending on the specific application and regulations.

The capacity of the tank trailer used can vary significantly depending on several factors, including the specific country, regulations, road infrastructure, and the intended use of the truck.

Some standard fuel tanker trailers have capacities around 40,000 to 42,000 liters (approximately 10,500 to 11,100 US gallons).
General Range: You'll likely find tank trailer with capacities ranging from around 20,000 liters (approximately 5,300 US gallons) up to 45,000 liters (approximately 11,900 US gallons) for general fuel and liquid transport.
Smaller Trailer: Smaller tank trailer for local deliveries in more populated areas might have capacities in the 10,000 to 20,000 liter range.
Larger Trailer: For long-haul transportation on better-maintained roads, larger capacity tankers, potentially exceeding 45,000 liters, might be used where regulations allow.

Operating a fuel tank trailer is a complex and safety-critical task that requires specialized training and adherence to strict procedures. Here's a general overview of the key steps and considerations involved. This is not a substitute for professional training.

1. Pre-Trip Inspection and Preparation:

Vehicle Inspection: Thoroughly inspect the tractor unit and the trailer, including tires, brakes, lights, hoses, connections, and the tank itself for any damage or leaks.
Documentation: Ensure all necessary paperwork is in order, including the bill of lading, safety data sheets (SDS) for the fuel being transported, and permits.
Personal Protective Equipment (PPE): Wear appropriate PPE, such as gloves, safety glasses, and fire-resistant clothing.
Emergency Equipment: Verify that fire extinguishers and spill response kits are readily accessible and in good working order.
Loading Procedures (at the loading terminal):
Secure the Vehicle: Properly park and secure the tractor-trailer, often with wheel chocks.
Grounding/Bonding: Connect grounding and bonding cables between the loading rack and the trailer to prevent static electricity buildup, which can ignite flammable fuels.
Connect Loading Arm/Hose: Carefully connect the loading arm or hose to the correct fill port on the tank trailer.
Verify Product: Double-check that the correct type and grade of fuel is being loaded into the designated compartments.
Monitor Loading: Closely monitor the loading process to prevent overfilling, using gauges and automatic shut-off systems.
Close and Secure: Once loading is complete, disconnect the loading arm/hose, close all valves and fill ports securely, and disconnect grounding/bonding cables.
Inspect Seals: Verify that all seals are in place and intact.

2. Driving and Transportation:
Safe Driving Practices: Operate the vehicle defensively, maintaining safe speeds and following all traffic laws. Be aware that a loaded tanker trailer has a higher center of gravity and different handling characteristics than a dry van.
Smooth Movements: Avoid sudden acceleration, braking, and sharp turns, as these can cause the liquid cargo to shift, potentially leading to loss of control.
Anticipate Braking Distances: Loaded tankers require longer stopping distances.
Route Planning: Plan routes carefully, avoiding areas with restrictions on hazardous materials or large vehicles.
Monitoring: Regularly check gauges and mirrors to ensure the load is secure and there are no issues with the vehicle.

3. Unloading Procedures (at the delivery point):

Secure the Vehicle: Park on a level surface, engage the parking brakes, and use wheel chocks.
Warning Signs: Place warning signs or cones as required.
Grounding/Bonding: Connect grounding and bonding cables between the trailer and the receiving tank.
Connect Unloading Hose: Carefully connect the unloading hose to the correct discharge port on the tank trailer and the receiving tank.
Verify Product and Connections: Double-check that the correct fuel is being unloaded into the correct tank and that all connections are secure.
Initiate Unloading: Begin the unloading process, following the specific procedures for the trailer's unloading system (e.g., pump, gravity).
Monitor Unloading: Continuously monitor the unloading process to prevent spills or overfilling of the receiving tank.
Disconnect and Secure: Once unloading is complete, disconnect the unloading hose, close all valves and discharge ports securely, and disconnect grounding/bonding cables.
Inspect Seals (if applicable): Verify that seals are in place after unloading.
Documentation: Complete all necessary delivery paperwork.

4. Post-Trip Procedures:

Vehicle Inspection: Conduct a post-trip inspection of the trailer and tractor, noting any issues or damage.
Reporting: Report any accidents, spills, or mechanical problems immediately.
Cleaning (if required): Clean the tank interior according to regulations if a different product is to be transported next.
Parking and Securing: Park the vehicle in a designated and secure area.

You must abide by all safe driving guidelines to operate a tank truck:

Smooth driving: You have to start, slow down, and stop very smoothly because of the high center of gravity and significant liquid variations. Additionally, be fluid when changing lanes and turning.
Braking: Use steady or controlled braking if you must stop quickly to prevent an accident. Refer to Section 2.13 if you can't recall how to cease utilizing these techniques. Additionally, keep in mind that your car could roll over if you turn quickly while braking.

Curves: Reduce your speed prior to a curve and increase it a little after you pass it. For tank vehicles, the speed limit on curves could be too high.
Stopping distance: Keep in mind how far you must stop. Keep in mind that stopping distances might quadruple on slick roadways. A truck with an empty tank may take longer to stop than one with a full tank.
Avoid overbraking, oversteering, and overaccelerating during skidding. If not, your car might skid. If either the drive wheels or the trailer wheels start to skid, your car may jackknife. You need to take action to get the wheels back on track when a car starts to skid.
