Kolkata, July 9 (IANS): A day after West Bengal Chief Minister Mamata Banerjee expressed her displeasure over two-wheeler users not wearing helmets, Kolkata police on Saturday imposed a "no helmet no petrol" rule forbidding petrol pumps from selling fuel to motorcyclists without helmets.

"No petrol pump within the jurisdiction of Kolkata police shall henceforth sell petrol to any such two-wheeler rider who comes to the petrol pump riding a two-wheeler without helmet as well carries a pillion rider without helmet," said a notification by the city police published on Saturday.

Observing that there was a "manifold rise" in instances of bikers and pillion riders not sporting helmets, the notification said, "Immediate and stringent action needs to be taken in accordance with law, to have greater deterrence and for prevention of the same."

Launching a road safety initiative "Safe Drive Save Life", the West Bengal Chief Minister on Friday had expressed alarm over rising accident deaths and called for strict adherence to traffic laws.
