As per the Motor Vehicles Act, 1988, what essential certificate must a transport vehicle carry to be considered validly registered in Assam?

The correct answer is Certificate of Fitness . Key Points Under the Motor Vehicles Act, 1988, specifically Section 56, a "Certificate of Fitness" is a mandatory requirement for all transport vehicles to be considered validly registered and legally operational on public roads. This certificate attests to the mechanical condition and roadworthiness of the vehicle, ensuring it is fit and safe for commercial or public use. Without a valid Certificate of Fitness, a transport vehicle's registration is deemed invalid, and operating it on the road can lead to legal penalties. The validity period of a fitness certificate for transport vehicles is typically one year, after which it must be renewed following a thorough inspection. While a Pollution Under Control (PUC) Certificate is also essential for all vehicles to comply with emission norms, and a Temporary Permit or No Objection Certificate (NOC) might be needed for specific scenarios, the Certificate of Fitness directly relates to the vehicle's structural and operational integrity for valid registration as a transport vehicle.
