A vehicle challan is an official document issued by traffic authorities to a driver or vehicle owner for violating traffic rules and regulations. It serves as a notice of the traffic offense committed and typically includes details such as:

- Date and time of the violation

- Nature of the traffic offense (e.g., speeding, illegal parking, running a red light)

- Penalty or fine amount

- Vehicle details (e.g., registration number, make and model)

- Information about the issuing authority

The recipient of the challan is usually required to pay the fine or contest the challan within a specified period. Vehicle challans can be issued manually by traffic officers or automatically through surveillance systems like speed cameras or traffic light cameras.
