What it is
What the speed governor certificate proves
CMVR rule 118 requires transport vehicles, with listed exemptions, to be fitted with a speed limiting device set to the prescribed speed. The certificate from the manufacturer or dealer records the device, its serial number and the set speed for that vehicle. It matters most at the fitness test, where a missing or non-working governor is a reason to fail, and after any repair to the device.

How to renew
4 steps, in order
PRACHSO does not issue or renew any government document. These are the steps on the official service, or the ones your appointed agent follows.
- 1
Keep the fitment certificate that came with the device, with the device serial number and the vehicle's chassis number.
- 2
Before each fitness test, have the authorised dealer check that the device works and is sealed.
- 3
If the device is repaired or replaced, get a fresh certificate from the authorised dealer for the new device.
- 4
Carry the certificate to the fitness test and keep a copy in the vehicle file.
Penalty for a lapse
A vehicle that needs a working speed governor and does not have one can fail its fitness test, which then puts the registration and the permit at risk. Running a vehicle that does not meet the prescribed construction and safety standards is an offence under Section 182A of the Motor Vehicles Act.
Common mistakes
Where fleets slip
- Losing the fitment certificate and finding out at the fitness test.
- Having the device repaired by a workshop that is not an authorised dealer, which leaves no valid certificate.
- Removing or tampering with the seal to run faster. It shows up at the next test.
How PRACHSO tracks it
The reminder goes to whoever has to act
PRACHSO keeps the speed governor certificate in the vehicle's vault with the device serial number, and adds it to the fitness renewal checklist so it goes with the truck to every test.
