Regularly renewing your PUC certificate ensures issues are identified and resolved, helping your vehicle run smoothly. Additionally, a valid PUC certificate reduces harmful pollutants, protects public health and promotes awareness about the importance of controlling vehicle emissions.
PUC Certificate Validity in Kerala
The validity of a PUC certificate in Kerala is determined by the vehicle type and its emission standards:
