RC Status or the registration certificate is the official document issued by the RTO authority when someone buys a new vehicle and registers it with the RTO. RC is used to identify the owner of the vehicle and for records of vehicles sold and bought. Vehicle registration is mandatory if you purchase any vehicle. You need to carry your RC with you all the time when you drive, if you're caught with a car without a valid RC, you might attract a fine or imprisonment depending on the circumstances.
