Motor vehicles must be equipped with an **explosion silencer**. This device is essential for reducing the **noise** produced by the engine while operating. According to regulations, it is prohibited to drive a vehicle that emits more **noise, gases, or smoke** than allowed. This is because excessive noise is not only annoying but can also be harmful to health and the environment.

Additionally, vehicles contribute to **pollution** by releasing toxic gases into the atmosphere. To minimize this impact, it is important that the exhaust system, which includes the silencer, functions correctly. A vehicle without a silencer could emit more gases and smoke than permitted, which is prohibited.

Therefore, it is mandatory for motor vehicles to be equipped with an explosion silencer to comply with noise and pollution regulations.
