Sleeper Bus Safety Rules in India: What Operators Are Being Asked to Fit
A plain summary of the 2026 sleeper bus safety measures reported in India: fire detection, emergency exits, driver drowsiness indicators, AIS-052 and AIS-119.
Short answer: after a series of fatal sleeper bus fires, the central government and the National Human Rights Commission moved in January 2026 to tighten sleeper bus safety. As reported, new sleeper coaches may be built only by accredited manufacturers, and existing sleeper buses are to be fitted with fire detection systems, emergency exits with hammers, emergency lighting and driver drowsiness indicators, and brought in line with the bus body standards AIS-052 and AIS-119.
This article summarises published reports. It is not legal advice. Requirements and deadlines are set by the Ministry of Road Transport and Highways and by state transport departments, so confirm the current position with your Regional Transport Office.
What was announced?
- Manufacturing: the Union Minister for Road Transport and Highways said that sleeper coach buses would be manufactured only by automobile companies and facilities accredited by the Centre (Autocar Professional, 10 January 2026).
- Existing buses: the same report lists four items to be retrofitted on sleeper buses already in service: fire detection systems, emergency exits fitted with hammers, emergency lighting and driver drowsiness indicators.
- Bus body code: the revised Bus Body Code, AIS-052, has applied from 1 September 2025.
What did the NHRC directions add?
According to Coach Builders India (10 January 2026), directions issued to the states following the National Human Rights Commission’s intervention include:
- Compliance with AIS-052 (bus body code) and AIS-119 (sleeper coach specifications), with non-compliant buses treated as unfit to operate.
- Removal of partitions or doors that enclose the driver’s cabin.
- Removal of sliding doors on sleeper berths, with curtains as the permitted privacy measure.
- A fire detection and suppression system (FDSS).
- Fire extinguishers of the specified capacity, accessible and regularly inspected.
- No chassis-extended sleeper buses.
- For new registrations, bodies built by approved body builders with approved layout drawings, emergency exits and hatches.
The same report describes a short compliance window for existing buses, after which non-compliant vehicles can be stopped and permits acted upon. Enforcement is carried out state by state.
Why were these measures taken?
Investigations into the fires pointed to recurring problems: flammable interior materials, blocked or missing emergency exits, enclosed cabins that delayed the alarm, and no fire detection. On a sleeper bus, passengers are lying down, often asleep, in narrow berths. Seconds of warning decide whether they get out.
What does “driver drowsiness indicator” mean for an operator?
Most sleeper services run through the night, and a drowsy driver is the other major risk on these routes. A driver drowsiness system watches the driver’s eyes and head with an infrared camera and sounds an alert in the cab when it sees signs of sleep. The technical specification that a device must meet for compliance is a matter for the authorities, so ask your RTO which devices and certificates are accepted before you buy.
Whatever the compliance route, the safety case is the same: an alert that wakes the driver, and a record that tells the operator it happened. See how drowsiness detection works on night buses.
What should a sleeper bus operator do now?
- Get the current order for your state from the transport department or RTO, in writing.
- Audit each bus against it: body code compliance, exits, hammers, lighting, cabin partition, berth doors, extinguishers, fire detection.
- Fix the structural items first. Exits and partitions are what let people out.
- Fit a fire detection and suppression system, and keep its certificate. See how FDSS works.
- Fit driver drowsiness monitoring and decide who responds to its alerts at night.
- Keep the paperwork: certificates, installation records and inspection dates for every bus.
- Brief crews on exits, extinguishers and what to do when an alarm sounds.
What goes beyond the minimum?
- A breath alcohol test before departure, so the driver starts the night fit to drive.
- Road-facing collision and lane warnings, for the hours when attention is lowest.
- Live tracking and an SOS button, so the control room knows where the bus is when something goes wrong.
- A gangway camera, to see the cabin when the driver cannot.

Confirm current requirements with your RTO.
What are AIS-052 and AIS-119?
AIS-052 is India’s bus body code, covering the safety, structure and design of bus bodies. AIS-119 sets out the specifications for sleeper coaches.
Is a driver drowsiness system required on sleeper buses?
Driver drowsiness indicators were among the items reported for retrofit on existing sleeper buses in January 2026. The accepted device specification is decided by the authorities, so check with your RTO.
Is a fire detection system mandatory in sleeper buses?
A fire detection and suppression system is among the measures reported for sleeper buses. Use an approved supplier and confirm the requirement for your state.
Does AirFi supply fire detection systems?
Yes. AirFi supplies and installs fire detection and suppression systems for buses, along with driver drowsiness monitoring, AI dashcams, alcohol testing and GPS tracking. Body-code work is done by approved body builders.
