KEY TAKEAWAYS
- Rule 125H of the Central Motor Vehicles Rules requires a VLTD (Vehicle Location Tracking Device) with emergency buttons in public service vehicles. Separate notifications extend it to national permit goods carriers and to N2 and N3 vehicles carrying dangerous or hazardous goods.
- New public service vehicles registered from January 1, 2019 must have a VLTD. Two-wheelers, three-wheelers and e-rickshaws are exempt.
- Compliance is checked on VAHAN: the device is registered against the vehicle, and RTOs check it at fitness certification and national permit authorization.
- On May 13, 2026, the Supreme Court directed that no public service vehicle get a fitness certificate or permit without a verified VLTD and emergency buttons reflected on VAHAN, and ordered retrofitting of vehicles registered up to December 2018.
- On September 15, 2026, the Court asked every state and union territory to file a Rule 125H compliance status report.
- The fastest route to compliance is a certified device, a confirmed VAHAN link, working emergency buttons and a device that stays powered and connected.
The VLTD rule has been on the books since 2016. For most of that time, enforcement was patchy. In 2026, that changed.
In May, the Supreme Court called it disturbing that fewer than 1% of transport vehicles carried a VLTD. It directed states not to grant a fitness certificate or permit to any public service vehicle until the device and emergency buttons are verified and reflected on VAHAN, and ordered older vehicles to be retrofitted.
In September, the Court went further. It asked every state and union territory to report on Rule 125H enforcement, and asked MoRTH to place on record its talks with vehicle manufacturers about fitting VLTDs before vehicles are sold.
For fleet operators, VLTD compliance is no longer a paperwork issue. It decides whether vehicles keep running.
In this blog, you will learn which vehicles need a VLTD, the key dates, how compliance is checked on VAHAN, why vehicles fail VLTD checks, and what to do now to get every vehicle compliant and keep it that way.
What is VTLD, in one line?
A VLTD is the in-vehicle tracking unit, type-approved to the AIS-140 standard and paired with one or more emergency buttons, that reports a vehicle’s location and alerts to the state’s monitoring system. For how the device works and how it differs from an ordinary GPS tracker, see what is a VLTD.
Which vehicles need a VLTD?
Three central notifications set the scope. States then add categories and phases of their own.
| Vehicle category | Rule or notification | Status |
| Public service vehicles (buses, taxis, cabs and other vehicles carrying passengers for hire) | Rule 125H, CMVR; G.S.R. 1095(E), November 28, 2016; S.O. 5453(E) and 5454(E), October 25, 2018 | Required on new vehicles registered from January 1, 2019; vehicles registered up to December 2018 must be retrofitted under the May 2026 Supreme Court order |
| Exempt | Rule 125H | Two-wheelers, three-wheelers and e-rickshaws |
| National permit goods carriers | G.S.R. 1081(E), November 2, 2018 | Required; checked at national permit authorization |
| N2 and N3 vehicles carrying dangerous or hazardous goods | G.S.R. 617(E), August 3, 2022 | Required on new models manufactured from September 1, 2022 and existing models from January 1, 2023 |
| State additions | State notifications | States set their own phases and may add categories |

How is VLTD compliance checked?
- The device is registered on VAHAN
Each VLTD’s IMEI number and make and model are uploaded to VAHAN and linked to the vehicle. For new vehicles, the vehicle manufacturer or its authorized agency does this. For retrofits, the VLTD dealer or fitment center links the device, a motor vehicle inspector checks the fitment, and activation details are uploaded to VAHAN (Meghalaya Transport Department SOP, October 2025). - Fitness certification checks it
Since May 2026, a public service vehicle can’t get its fitness certificate unless the VLTD and emergency buttons are verified and reflected on VAHAN. The Supreme Court has also directed states to integrate VLTD installation and functionality with VAHAN for real-time compliance monitoring. - National permit authorization checks it
For national permit vehicles, VAHAN looks for a registered VLTD before issuing the authorization. That’s what the message “can’t issue NP authorization as VLTD device not installed on this vehicle” points to: VAHAN has no active VLTD linked to that vehicle. - State monitoring centers watch the data
Once active, the device reports to the state’s vehicle tracking platform. Emergency button alerts go to the state monitoring center, which coordinates with the State Emergency Response Support System (SERSS).
Why do vehicles fail VLTD checks?
Most failures come down to a handful of fixable gaps.
| Reason | What fixes it |
| The device isn’t type-approved to AIS-140 | Replace it with a certified VLTD from a manufacturer empaneled in your state; see AIS-140 certified GPS vendors in India |
| The device is fitted but not linked on VAHAN | Ask the dealer or manufacturer to complete VAHAN registration and activation, then confirm it shows against the vehicle |
| A replaced or moved device still shows against the old vehicle | Update the VAHAN link after every replacement or transfer |
| Emergency buttons not fitted or not working | Fit and test every button, and retest after any wiring work |
| The device is offline (power cut, expired SIM, tampering) | Keep devices powered and SIMs active, and use devices that alert when unplugged |
| An older public service vehicle was never retrofitted | Retrofit now; the May 2026 order covers vehicles registered up to December 2018 |

What should fleet operators do now?
- and hazardous goods carriers, plus any state additions.
- Check each device: is it a type-approved AIS-140 VLTD with working emergency buttons?
- Check VAHAN: confirm every device shows against the right vehicle.
- Retrofit older vehicles that don’t have a VLTD, starting with those due for fitness or permit renewal. For budgeting, see AIS-140 device cost in India.
- Keep devices live: power, SIM validity and tamper alerts, with one person responsible for following up on offline units.
- Keep records of fitment, VAHAN registration and button tests for inspections.

Beyond compliance: Using VLTD data
A VLTD already reports location, speed and alert events. With the right platform behind it, the same data supports trip replay for disputes, geofences for route adherence and early warning when a unit goes offline.
What AIS-140 doesn’t ask for is engine data. Fault codes, coolant temperature and fuel use sit outside the standard, so fleets that want vehicle health and fuel insights need a device that does both. For how VLTD data is used and where it stops short, see what is a VLTD guide. For the bigger picture, see AIS-140 vs advanced telematics. For running VLTD compliance and fleet telematics on one device, see VLTD and fleet telematics: one device or two.
How does Intangles help fleets meet VLTD rules?
Intangles’ InGenious device is AIS-140 certified and supports both BS-IV and BS-VI vehicles, so a mixed-generation fleet can standardize on one device for compliance. It raises an alert when it’s unplugged or powered off, so an offline unit is caught before it surfaces at a fitness or permit check.
It connects through the vehicle’s OBD port with no modifications, and the same device feeds the InRoute platform with:
- location tracking, with live position and trip history;
- predictive health monitoring, which flags developing engine faults early;
- fuel monitoring.
Intangles works with Indian fleets in trucking and transit.
Discover how Intangles can keep your fleet VLTD compliant and turn the same device into location, vehicle health and fuel insights.
Frequently Asked Questions
Is a VLTD mandatory for goods vehicles?
For national permit goods carriers and for N2 and N3 vehicles carrying dangerous or hazardous goods, yes. Other goods vehicles depend on state rules, so check your state’s notification and the category-wise AIS-140 guide.
Do older vehicles need a VLTD?
Older public service vehicles do. In May 2026, the Supreme Court ordered states to retrofit VLTDs and emergency buttons in public service vehicles registered up to December 2018, and directed that no fitness certificate or permit be granted until the devices are verified and reflected on VAHAN.
What does "can't issue NP authorization as VLTD device not installed on this vehicle" mean?
It means VAHAN has no active VLTD registered against that vehicle, so the national permit authorization is blocked. Fit a certified VLTD, ask the dealer or manufacturer to register and activate it on VAHAN, and confirm it shows against the vehicle before applying again.
Who registers a VLTD on VAHAN?
For new vehicles, the vehicle manufacturer or its authorized agency registers and activates the VLTD on VAHAN. For retrofits, the VLTD dealer or fitment center links the device’s IMEI to the vehicle. Either way, the owner should check that the registration shows correctly, especially after replacing or moving a device.
Does a VLTD have to be AIS-140 certified?
Yes. Rule 125H requires the device and emergency buttons to meet AIS-140, and devices are type-approved by authorized test agencies such as ARAI and ICAT. An ordinary GPS tracker doesn’t count, even if it reports location.
Can one device handle VLTD compliance and fleet management?
Yes, if it’s certified and built for both. Intangles’ InGenious device is AIS-140 certified and also feeds location, vehicle health and fuel data into Intangles’ predictive analytics.
