Truck dangerous goods marking: Types of marking on trucks
There are different types of truck dangerous goods markings that must be affixed depending on the goods being transported and the type of vehicle.:
- 1. ADR marking for trucks : The ADR plate is a rectangular, orange marking that is affixed to the front and rear of the vehicle. It provides information about the hazard class of the goods being transported and the substance number (UN number), which allows for detailed identification of the hazardous substance.
- 2. LQ marking for trucks : LQ stands for "Limited Quantities." This marking is required when transporting small quantities of dangerous goods that qualify for certain exemptions in the transport regulations. The LQ marking usually consists of a special square symbol.
- 3. Marking of trucks A, K and E : These designations represent specific marking regulations relating to the transport of dangerous goods:
- Marking LKW A : Applies to substances and goods of hazard class 1, e.g. explosive substances.
- LKW K marking : These are markings for substances with special requirements, such as radioactive materials.
- Truck E marking : This marking is generally intended for the transport of flammable liquids (dangerous goods class 3).
- 4. TIR truck marking : The TIR procedure allows for the transport of goods under customs seal across international borders. The TIR (International Road Transport) truck marking is affixed to vehicles operating under this system. TIR plates are affixed to the front and rear of the vehicle to facilitate customs clearance and minimize inspections.
- 5. Truck tire markings : Truck tire markings are also important when it comes to safety. Tires used for the transport of dangerous goods must comply with specific regulations. The markings contain information about load capacity, speed rating, and, if applicable, special requirements relevant to the transport of dangerous goods.
