What it means
For camera-generated challans, the flow is: a camera detects a violation, the system builds an evidence record, an officer reviews it, and the approved record goes to the eChallan system, which notifies the vehicle owner using VAHAN registration data. Officer review before issue reduces wrong challans and complaints.
How it applies in India
Rule 167A of the Central Motor Vehicles Rules (notification G.S.R. 575(E), 11 August 2021) sets the rules for electronic enforcement. Footage from a device with an electronic stamp of location, date and time can be used to issue challans for offences including speeding, riding without a helmet, driving without a seatbelt, jumping a red light, using a handheld phone, driving against the authorised flow of traffic and lane violations. The rule also asks states to place devices on high-risk, high-density corridors of national and state highways and at critical junctions in major cities. Each evidence record should therefore carry a clear image of the vehicle and plate, the measured value where relevant, and the time and place of the offence.
