In India, the use of pressure horns or multi-toned horns on vehicles is regulated by the Motor Vehicles Act, 1988, and subsequent amendments. The use of such horns is considered a nuisance and can cause inconvenience, discomfort, or danger to other road users.
The law prohibits the use of pressure horns or multi-toned horns on vehicles except for certain emergency vehicles such as ambulances, fire trucks, and police vehicles. The use of such horns by other vehicles is strictly prohibited.
If a vehicle is found to be using a pressure horn or multi-toned horn, the driver/owner of the vehicle may be fined. The fine amount may vary from state to state, but it can range from Rs. 1,000 to Rs. 5,000 or more.
