What Is the Most Common Cause of Truck Fires and How to Prevent Them?

Truck fires don’t happen out of nowhere. Most of the time, they start because small problems are ignored for too long. A truck runs every day, for long hours, with a heavy load, heat, fuel, and electricity all working together. If even one thing goes wrong, fire can start.

That is why understanding truck fire causes and keeping a proper truck fire extinguisher inside the vehicle is very important.

Let’s talk about this in simple words.

The Most Common Cause of Truck Fires

Electrical Problems: In most cases, truck fires start because of electrical problems. Like loose wiring, damaged cables, old insulation, or poor battery connections are very common in trucks. Over time, vibration and heat weaken these parts. And this one issue is enough to start a fire.

Fuel/Oil Leakage: Another major reason is fuel or oil leakage. Diesel or oil leaking near the engine or exhaust area can catch fire very fast. Many drivers don’t notice small leaks until it is too late.

Overheating: Overheating is also a big issue. Because trucks usually run for hours every day. When cooling systems fail or engines overheat, fire risk increases quickly.

Truck-Type Specific Fire Extinguisher Solutions (Very Important)

This is where many safety plans fail. Different trucks require different fire extinguishing systems.

Refrigerator Trucks (Reefer Trucks)

Refrigerator trucks have:

• Electrical refrigeration units
• Compressors and control panels

👉 Recommended Fire Extinguisher: CO2 Fire Extinguisher

 CO2 is ideal because:

• It is safe for electrical fires
• Leaves no residue
• Does not damage refrigeration equipment

 Chemical Tanker Trucks

Chemical tankers carry:

• Flammable or hazardous liquids
• High-risk chemical substances

👉 Recommended Fire Extinguisher: Mechanical Foam Fire Extinguisher (Cartridge Type)
Foam is effective because:

• It suppresses flammable liquid fires
• Prevents re-ignition
• Creates a protective layer over chemicals

Fuel & Oil Tanker Trucks

These trucks carry highly flammable liquids.

👉 Recommended Fire Extinguisher: Mechanical Foam – Cartridge Type System

This is essential for rapid fire knockdown and safety compliance.

General Cargo & Commercial Trucks

For standard trucks carrying goods, with engine, wiring, and fuel risks:

👉 Recommended Fire Extinguisher: ABC Dry Chemical Powder Fire Extinguisher

It effectively handles:

• Class A (solid materials)
• Class B (flammable liquids)
• Class C (electrical fires)

Why Truck Fires Become Serious Very Fast

A truck carries fuel, oil, electrical wiring, and sometimes flammable cargo. Once a fire starts, it spreads quickly. The size of the vehicle makes it worse. Many times, drivers panic because they don’t have a fire extinguisher vehicle setup nearby. By the time help comes, the damage is already done. This is why early action is very much more important than anything else.

How a Truck Fire Extinguisher Can Save You

A truck fire extinguisher is not just a safety rule. But it is a real lifesaver, if you know. If a fire is small, you can stop it immediately. For example, engine fire, wiring fire, or cabin fire can be controlled before it grows. And this quick action can save the truck, the goods, and the driver.

Truck Fire Extinguisher Requirements You Should Follow

Now, after knowing how truck fires start, you need to keep in mind the basic truck fire extinguisher requirements. But many people ignore them. 

The extinguisher should:

• Be inside the cabin or easily reachable
• Be fixed properly, not loose
• Be checked regularly
• Be suitable for vehicle fires

An expired or empty extinguisher is as good as not having one. That being said, you should always refill or change the fire extinguisher.

How You Can Prevent Truck Fires

In order to prevent truck fires, you need to maintain your vehicle frequently. You don’t need big changes, for example. Here are the basic rules you should remember:
