Hazardous substances are substances that, due to their properties such as explosiveness, toxicity, flammability, corrosiveness and the like, can endanger the life and health of people, cause material damage and have a harmful impact on the environment. Also, raw materials from which hazardous substances and waste are produced are considered dangerous substances, if they have the properties of these substances. According to the Act on Transport of Dangerous Goods and ADR, dangerous goods are divided into nine groups, i.e. classes, namely: 1. explosive substances, 2. gases, 3. flammable liquids, 4. flammable solids, 5. oxidizing substances or oxidants, 6. toxic substances, 7. radioactive substances, 8. corrosive or corrosive substances, 9. other dangerous substances. The topic of this final thesis is explosive substances (class 1), that is, the transport of explosive substances in road traffic. Explosive substances are solid and liquid chemical substances that have the property that, during external actions such as impact, friction or heat, they release gases or energy in the form of heat through explosive chemical decomposition.
