While driving, drivers must avoid producing unnecessary or disturbing noise. Such noise may result from driving behavior, such as harsh acceleration or excessive engine use, but also from improperly secured loads or other actions related to driving. This rule is important not only for the comfort of other road users but also for environmental protection and public peace.
A key component is the vehicleβs exhaust silencer, which must always be kept in good working condition and must not be modified. Altering or removing the silencer increases noise and is prohibited.
The use of audio devices in the vehicle, such as radios or music systems, must also respect maximum sound limits. The volume must not disturb others or interfere with safety, for example by preventing the driver from hearing important sounds like horns or emergency sirens.
Anti-theft alarm systems must also comply with specific limits. The sound must be limited in duration and intensity, avoiding prolonged or excessively loud noise.
In summary, drivers must behave responsibly in terms of noise, avoiding any unnecessary disturbance. Violations of these rules result in administrative fines.
