What is a Placard on a Truck?

Placards are signs used to indicate the contents of a truck. These signs typically display information about hazardous materials. Trucks carrying these materials are required to have a placard on each side of the cab. Some trucks also have additional signs on the cab. These placards help keep the public and emergency responders informed.

Placards must be displayed on all four sides of a transport vehicle, as per 49 CFR regulations. Some placards are permanently mounted to a truck, while others can be placed on a trailer. Placards must be easily readable and well-attached to the truck to avoid being mistaken for other markings.

A placard on a truck is important to keep other drivers and emergency services aware of hazardous materials. They alert drivers to the presence of such materials, which can cause accidents and secondary injuries.

Where Must Placards Be Displayed?

Placards are signs placed on the outside of bulk packages or vehicles that transport hazardous materials. They identify the type of cargo and classify it according to hazard levels. They must be legible from all four directions, be 9.84 inches square, and be located 3 inches from other markings.

There are several different types of placards. DOT placards are larger and more durable than hazard labels, and communicate the hazards of dangerous goods. In addition to the hazard classification, DOT placards can also display the name of the manufacturer. DOT placards can be displayed on the outside of a large container.

In addition to placards, other safety marks must be displayed on large means of containment. For example, a highway tank transporting gasoline requires a UN number. This number must be displayed on the placard and on a rectangular orange panel that is placed next to the tank. The UN number must be legible and not have the prefix “UN”.

What is the Hazmat Symbol?

When a truck is hauling hazardous materials, you can recognize the truck by its hazmat symbol. These placards are required by the Department of Transportation and feature different pictures and numbers to identify the different classes of hazardous materials that are transported. There are nine different classes of hazardous waste, and each of these signs will bear the number that corresponds to that class.

The hazmat symbol indicates the presence of poisonous or hazardous materials. It is a white sign with black vertical stripes. Hazardous materials may include hazardous waste, dry ice, and asbestos. While hazmat class 1 is considered to be the most dangerous, all hazmat classes have their own hazards.

A Hazmat placard has a number of other features, but they share common characteristics. The hazard symbol and class number are both prominent and easily visible. In addition to their visual appearance, Hazmat placards can contain text as well. The text on the placard must be legible and written in English. The placards are often placed on the exterior of the vehicle.

What Does 1203 Mean on a Truck?

The number 1203 is used to identify a class three flammable liquid. Fuels with this placard have an ERG guide, a 4-digit UN number, and a graphic describing the hazard class. Often, the placard will state if the fuel is gasoline or petrol or has been mixed with ethyl alcohol. These substances have very high flammability, and water will not put them out in a fire.

Hazardous material placards must be placed on trucks. These placards must meet certain specifications. These placards are used on cylinders, trucks, and other vehicles that transport hazardous materials. Some trucks will have additional markings on their placards.

What Requires HazMat Placards?

HazMat placards are required by law for carriers of certain hazardous materials. These placards must be displayed on all vehicles and freight containers that transport hazmat materials.

HazMat placards must be visible from both sides and ends of a truck. Moreover, the placard must be easily readable from all directions. There are specific requirements for placards based on the amount of hazardous materials carried on a vehicle.

HazMat placards can be yellow or white, indicating the presence of oxidizers. Oxidizers are chemical compounds that combust when mixed with oxygen. Common oxidizers are ammonium nitrate, potassium nitrate, and nitric acid. Those substances that are toxic or deadly should also be indicated by a sign with a skull and crossbones image or a biohazard symbol.

Why Must Placards Be Displayed on Each Side?

In addition to placards, other safety marks must also be displayed on a large means of containment. For example, a highway tank transporting gasoline must display a UN number. This number must be visible on the placard and on a rectangular orange panel.

While DOT requires carriers to display four placards on each side of a truck, some carriers choose to place two additional signs on the cab of the truck for better visibility.

When Must Placards Be Removed?

Placards and special marks on trucks are required by law if they transport dangerous goods. The type, quantity, and use of the goods must be specified on the placards.

Placards for general freight vehicles must be 250 mm x 250 mm in size. They should be clean, legible, and unobscured.
