In India, the use of horns on vehicles is regulated by the Motor Vehicles Act, 1988, and subsequent amendments. The law prohibits the unnecessary or continuous use of horns in a manner that causes inconvenience, discomfort, or danger to other road users.
The use of horns in silence zones, such as hospitals, schools, and residential areas, is strictly prohibited. The law also prohibits the use of horns between 10 pm and 6 am in residential areas, except in cases of an emergency.
If a vehicle is found to be using a horn needlessly or continuously or in silence zones, 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.
