Taking photos of drivers and vehicle owners violating traffic rules is difficult

Unless a person has already activated his or her camera in the mobile or elsewhere, it is very difficult to take drivers or vehicle owners violating traffic rules, especially if the person is driving a vehicle, usually at a high speed.
The goa government has launched a scheme of rewarding those who are reporting traffic violators, sending the photo to the whatsapp number provided, however the person should be very patient to trap the traffic violators.
There are many people who having 3 adults on a single scooter, yet they are never reported.
Additionally some of the drivers and vehicle owners who have received the challans under the scheme, are saying that they are receiving duplicate or triplicate challans, as multiple people are reporting the same violation.
