Introduction
A draft from India’s road transport ministry would require new trucks and buses to carry driver drowsiness and lane-departure warning systems. If you run a fleet, the real question isn’t only “when does this apply?” It’s what the draft means for the vehicles you buy, the drivers you manage and the safety tools you already use. A driver behaviour monitoring system is one way fleets are already tackling the same problem.
Please note: This article is general information based on media reports of a draft. It is not legal advice. Check the official notification and your vehicle manufacturer, and ask a qualified professional about your situation.
A truck driver finishes a long night run and starts another leg before sunrise. The road is empty, the cab is warm and the steering drifts a little. A beep from the dashboard wakes him just before the vehicle crosses the lane line.
That beep is what these systems are for. And the draft rules suggest that sooner or later, new trucks and buses will come with them as standard.
What the Draft Proposes, in Plain Words
According to media reports, the Ministry of Road Transport and Highways (MoRTH) has proposed amendments to the Central Motor Vehicles Rules that would require a package of advanced driver assistance systems on new buses and trucks. Two of them matter here:
- Driver Drowsiness and Attention Warning System (DDAWS): monitors for signs of drowsiness, using inputs such as the driver’s steering movements, lane position and, in some designs, facial tracking, and warns the driver with an alert.
- Lane Departure Warning System (LDWS): warns the driver when the vehicle begins to drift out of its lane, using visual, audible or vibration signals.
Reports say the same package includes advanced emergency braking, a blind-spot information system and a moving-off information system.
What’s Certain and What Isn’t
This is still a draft, so treat every date as provisional.
| Point | What reports say |
| Status | Draft, open for public consultation. After that, MoRTH reviews objections and suggestions before finalising |
| Earlier draft (reported 2025) | Requirement for new models from April 2026 and existing models from October 2026 |
| Latest reported draft (October 2026) | New truck and bus models to need the systems from January 2027, with a revised braking standard and electronic stability control for trucks from October 2027 |
| Standards named | Reports mention AIS-184 for DDAWS and AIS-188 for LDWS |
| Taxis | Reported to be getting drowsiness and attention-warning systems too |
Because dates differ between reports and drafts, and may change in the final notification, don’t plan around a single date. Plan around the direction.
Who Does It Apply To?
As reported, the draft is about new vehicles: new models first, then models already in production. It is framed as a fitment requirement on manufacturers, not as an order to retrofit trucks and buses that are already running.
That’s the reported picture, not a legal reading. Whether and how anything applies to your existing fleet is something to confirm in the final notification.
What It Means for Your Fleet
| Area | What to think about |
| New vehicle purchases | Ask your dealer or manufacturer which models will carry DDAWS and LDWS, and which standard they meet |
| Your existing fleet | The draft, as reported, targets new vehicles. Many fleets will still choose to add driver monitoring voluntarily |
| Operations and schedules | A warning system doesn’t replace rest. Rosters, night runs and long hauls still decide how tired drivers get |
| Drivers | These systems can use cameras and facial tracking, so explain what’s monitored and why |
| Data | Check whether warnings stay in the cab or are also reported to you |
| Insurance and customers | Some customers and insurers may start to ask about driver-fatigue controls |
Cab Warning vs Fleet Visibility: Know the Difference
An in-cab system built into a new vehicle warns the driver. It’s designed to prevent an accident in the moment. It doesn’t always tell you, as the fleet owner, that the warning happened, how often or with which driver.
A fleet-side driver monitoring system works differently. It uses cameras and analysis to detect fatigue, drowsiness or distraction, sends alerts to the driver and the vehicle owner, and keeps reports. That matters because fatigue is usually a pattern: the same driver, the same time of night, the same route.
You don’t have to pick one. In-cab warnings help prevent the incident. Fleet-level records help you fix what keeps causing it.
Fatigue: What Actually Works
Technology helps, but the biggest levers are still on the management side:
- Realistic schedules. Don’t plan trips that quietly require drivers to push through the night.
- Proper rest. Follow the working-hour and rest rules that apply to your drivers.
- Watch night runs. Fatigue risk is higher during late-night and early-morning hours. See our guide on night driving monitoring with GPS.
- Encourage honesty. Drivers should be able to say “I’m too tired” without being punished.
- Track patterns. One alert is an event. Ten at 3 a.m. is a scheduling problem.
Privacy and Driver Trust
Camera-based monitoring collects personal data, including facial data. That makes trust important, and it brings data protection into the picture.
- Tell drivers what’s monitored and why, in plain language.
- Limit who can see footage and reports.
- Decide how long data is kept.
- Use the data to coach, not only to punish.
- Check the data protection rules that apply to you, including India’s DPDP Act, which is being brought in step by step.
Most drivers accept monitoring when they understand it, and when they see it also protects them from blame in an incident.
What to Ask When You Buy or Retrofit
- Which standard does the system meet, and can the vendor show documentation?
- Does it detect drowsiness, distraction or both?
- How does it warn the driver: sound, vibration or both?
- Are alerts and events also sent to the fleet owner?
- What data does it store, and where?
- How are false alerts handled?
- What happens at night, in poor weather or with drivers wearing glasses or caps?
- Can it identify unauthorised drivers?
- What’s the support and installation process?
If a vendor claims compliance with a specific standard, ask to see the evidence rather than relying on the claim.
A 30-Day Plan
| When | What to do |
| Week 1 | Note the draft’s status, and list your fleet by vehicle type and age |
| Week 2 | Ask your dealers and manufacturers what their upcoming models will include |
| Week 3 | Pilot driver monitoring on three to five vehicles, ideally on night or long-haul routes |
| Week 4 | Review alerts with drivers, write a short policy and decide what to roll out |
Common Mistakes
- Treating the draft as final law, or ignoring it completely
- Assuming an in-cab warning will also reach you
- Relying on warnings instead of fixing schedules
- Rolling out cameras without telling drivers
- Choosing a system without asking for compliance evidence
- Ignoring false alerts until people stop trusting the system
- Waiting for a final date before doing anything
How SAHAJ GPS Helps
SAHAJ GPS Vehicle Tracking System includes driver behaviour monitoring for fleets. According to the website, its Driver Monitoring System:
- Uses camera-based analysis to monitor eye movement, head position, facial expressions and alertness
- Raises instant alerts for fatigue, drowsiness, distraction and unsafe head position
- Can identify unauthorised drivers
- Provides violation and safety-score reports that highlight overspeeding, harsh braking and unsafe manoeuvres
- Offers incident analysis and reconstruction from recorded data
- Gives access to alerts and reports on web and mobile
- Is meant to be used transparently, so drivers know they are being monitored
It also offers video telematics with ADAS and DMS features, and instant alerts for events such as over-speeding and zone activity. For the wider picture, see our guide to fleet safety management in India.
One honest note: the website doesn’t mention lane departure warning, or compliance with the standards named in the draft. If you need those, ask the team directly, and ask for documentation.
Frequently Asked Questions
Is a driver drowsiness warning system mandatory in India?
Not yet as a final rule. It’s in a draft notification, so the requirement and dates may change. Check the official notification.
Which vehicles will the drowsiness and lane-departure rules cover?
As reported, new buses and trucks, with reports also mentioning taxis. Check the final notification for exact categories.
Do I have to retrofit my existing trucks and buses?
The draft, as reported, is aimed at new vehicles and models. Confirm what the final rule says. Many fleets add driver monitoring voluntarily.
What is a lane departure warning system?
It warns the driver when the vehicle begins to leave its lane, using visual, audible or vibration alerts.
What’s the difference between an OEM drowsiness warning and a fleet driver monitoring system?
An OEM system warns the driver in the cab. A fleet-side system also sends alerts and reports to the owner, so you can spot patterns.
Does GPS tracking replace these systems?
No. GPS shows where the vehicle is and how it’s driven. Drowsiness and lane-departure systems detect alertness and lane drift. They work best together.
Final Thoughts
The draft will change, and so may the dates. But the direction is clear: more of the safety job is moving into the vehicle itself. Fleets that prepare now, with sensible schedules, a clear driver policy and a tested monitoring setup, won’t be caught off guard whenever the final rule arrives.
