Keralites have a penchant for defying signboards. Hundreds of sign boards dot Kerala that are never expected or even meant to be obeyed. Thus we have the no photography signs at the most photographed Secretariat in Trivandrum and tourist spots like Thenmala. Speed limits are near zero within Secretariat or even on the fly over at Palayam (20 km) where Ministers glides through in their luxury cars, oblivious of the speed limits.
This example is from GPO, Trivandrum.
