Rules for Using Emergency Vehicle Lights and Sirens
Only authorised vehicles (ambulance, fire, police) may use sirens and flashers. Misuse is a criminal offence.
Only vehicles authorised by the government — ambulances, fire engines, police vehicles, and select VIP vehicles — may use sirens and coloured flasher lights. The Supreme Court (2013) banned red beacons for VIPs. Unauthorised use of any beacon or siren attracts a ₹5,000 fine.
Penalty Under Law
Unauthorised use of siren/flasher: ₹5,000 (Sec. 177 MV Act). Vehicle may be impounded.

What the Law Says
CMVR Rule 108: Multi-tone horns, sirens, and flashers are reserved for emergency vehicles only. Rule 120: Specific beacon colours — red/blue (police), blue (ambulance, fire). The Supreme Court in Abhay Singh vs Union of India (2013) banned red beacons (lal batti) for all vehicles except emergency services. The government notification (2017) further restricted beacon use to: ambulance, fire, police, and a limited list of constitutional functionaries.
💡 Why This Rule Exists
Emergency vehicles need a clear path to save lives. When non-emergency vehicles use sirens and flashers (often to assert VIP status or clear traffic), it degrades the credibility of real emergency signals. Drivers become desensitised and stop yielding — costing lives when a real ambulance cannot get through. The ban on VIP beacons was a landmark decision against privilege on the road.
