Mumbai: Ahead of the HSRP installation deadline of Aug 15, activists flagged violations. They pointed to the use of ordinary nuts and bolts instead of tamper-proof snap locks for HSRP number plates. “HSRP fitted to my SUV was done with a plastic case resulting in it falling two days later,” said a retired RTO official. Transport commissioner Vivek Bhimanwar said, “In general, I cannot comment on individual complaints. But if specific vehicle numbers are shared, I can look into them.” PTI
