Those who have made alterations to their vehicles so that it makes more noise may soon have to pay hefty fines as the government is looking at imposing heavy penalties on such modifications that exceed the prescribed noise limits.
These alterations are usually made with the specific intention of making more noise and attracting attention to their vehicles, besides causing noise pollution.They also pose safety hazards. The proposal is being considered under the amendments to the Motor Vehicle Act.
Noise emanating from vehicles differ based on the vehicle’s construction, the condition in which they are maintained and modifications done on the vehicle illegally .
“Any changes to the approved design of the vehicles or other alterations are not permitted under the Central Motor Vehicle Rules,“ said Rashmi Urdhwareshe, the director of the Automotive Research Association of India (ARAI).
“In the proposed amendments, there is a call for heavy penalty for any vehicular alterations,“ she said .
Vehicles by themselves are not intended to be noisy but noise emits from the tyres, the interaction of tyres with the road surface, structural noise and maintenance of vehicles by the ow In India that prescribed range is 74 to 80 decibels (dB) for most vehicles. These regulations are similar to the European regulations.
In practise, however, Indi ners. So, there are prescribed limits beyond which this noise should not increase, legally. an vehicles make far more noise because of the sheer density of vehicles on road, the surface of the roads (of ten ill maintained), overlo ading of vehicles and ille gal modifications, among other things.
“Once a vehicle is designed to emit a particular amount of sound, it is the user’s responsibility to not increase the noise any further,“ said Urdhwareshe. It must be noted that not all vehicles that make more noise are necessarily breaching the limits but this can still be considered noise pollution because according to Urdhwareshe, “One has to also remember that any undesirable sound is called noise is also linked with the noise quality . Even when two vehicles generate same dB values one could be very irritating noise.“
ARAI tests and approves vehicles for noise provided they meet the upper limit set by law. In the last few years, a lot of engineering effort has gone into making diesel vehicles considered noisier -quieter within the cabin and outside.
Interestingly , there is a reverse story playing out in case of electric vehicles in Europe. They are so quiet that when they pass on roads even at high speeds they make very little noise. Certain associations in Europe have demanded that electric vehicles make some noise so that they don’t pose safety risks to pedestrians and visually challenged individuals.
