In simple words
A VLTD is a tracking device with safety functions such as an SOS button and tamper alerts. AIS-140 is the Indian standard that describes these devices for applicable vehicles.
Step by step
The device is fitted in the vehicle
It reads GPS and vehicle status
It sends data to the tracking platform
The platform forwards data where the rules require it
SOS and alerts reach the right people
Limits to know
A certificate on the device does not by itself mean a state portal accepts it. Always check acceptance for your state.
Questions we hear often
Who needs a VLTD?
It depends on the vehicle category and the state. Call us.
Is a normal GPS tracker enough?
Not always. Check the rule for your vehicle.
Does the SOS call the police?
It sends an alert. What happens next depends on the platform and the response process.
