What does "UN 78" on a car mean?
Designation UN 78** refers to the classification of dangerous goods adopted United Nations. Digit 78 is a unique identifier for a group of substances that are considered corrosive (corrosive) and capable of causing serious damage if improperly transported. This category includes:
- 🧪 Acids (sulphuric, hydrochloric, nitrogen, etc.)
- 🧴 Alkalis (sodium hydroxide, potassium)
- 🔋 Battery electrolytes (eg for lead acid batteries)
- 🧴 Chemical reagents for industry
It is important to understand that UN 78 - this is not just a warning, but part international ADR agreement (European Agreement concerning the International Carriage of Dangerous Goods by Road), which regulates the transport of dangerous goods by road. If your vehicle has this sticker, it means you are carrying substances that are subject to strict safety regulations.
Why does a car have to have a UN 78 sticker?
Designation sticker UN 78 performs several critical functions:
- Warning for other road users and rescue services about the potential danger of the cargo.
- Identification type of hazardous substance in case of an accident or emergency.
- Compliance with the Law - according to

For example, if a car with UN 78 gets into an accident, rescuers will be aware that there may be corrosive substances inside and will take appropriate precautions. Without labeling, the risk of incorrect actions (and, as a result, poisoning or burns) increases significantly.
If you are transporting batteries or chemicals, even in small quantities, check with your supplier to see if labeling is required UN 78. Some substances fall under exceptions, but it's better to be safe than sorry.
What fines are there for lack of marking?

| Incorrect documentation | 2 000–2 500 ₽ | 20 000–30 000 ₽ |
| Transportation without permission (if required) | 5 000–10 000 ₽ | 50 000–100 000 ₽ |
In addition to fines, the inspector may prohibit further movement until the violations are eliminated. In particularly severe cases (for example, when transporting a large consignment of acids without documents), it is even possible vehicle seizure.
⚠️ Attention! If you transport dangerous goods across the EAEU or Europe, fines may be significantly higher - up to 5 000 € for lack of marking.
How to properly place the UN 78 sign on a car?
Requirements for placing a dangerous goods sign are regulated ADR and Russian Rules for the transportation of dangerous goods. Here are the key points:

250×250 mm, for large vehicles -400×400 mm. - 🔴 Color: orange background with black border and black numbers (for UN 78 — additionally an image of a test tube with liquid).
- 📄 Documents: next to the sign there must be a plate with the UN number and hazard number (e.g.
8for corrosive substances).
☑️ Preparing a vehicle for transportation UN 78
If you are transporting cargo in a tank or container, the sign UN 78 must be duplicated on all four sides. For passenger cars (for example, when transporting batteries), one sticker on the rear window is sufficient.
What documents are needed to transport goods marked “UN 78”?
In addition to the marking itself, the driver is required to carry with him a package of documents:
- Transport document (invoice) indicating:
- Names of the substance (for example, “Sulfuric acid, 80%”)
- Hazard class (
8for corrosive) - UN numbers (
1830for sulfuric acid,1789for sodium hydroxide)
⚠️ Attention! If you are transporting UN 78 for personal purposes (for example, a battery for your car), markings and an emergency card are enough. For commercial transportation, a full package of documents is required.
What happens if an inspector stops a car without documents at UN 78?

Frequent mistakes when transporting goods marked “UN 78”
Even experienced drivers sometimes make mistakes that lead to fines or accidents. Here are the most common:
- 🚫 Using homemade stickers instead of certified marks. Such markings do not comply with GOST and do not protect against fines.
- 📦 Incorrect packaging - for example, transporting acids in plastic canisters not intended for corrosive substances.
- 📝 No emergency card or its outdated version (for example, without emergency numbers).
- 🚛 Transportation without special equipment (for example, without neutralizers or protective equipment).
Another common mistake is ignoring cargo placement rules. For example, acids should not be transported near organic substances (gasoline, oil), as this may lead to a chemical reaction. All requirements are specified in Appendix B to ADR.
Even if you are transporting a small amount of a corrosive substance (for example, 1 liter of acid), the marking UN 78 and an emergency card are required. Exceptions apply only for household quantities (up to 30 ml per package).
