As many as 3,431 pillion riders were fined by traffic police on Day 1 of action against bikers and pillion riders without helmets. Riders were unhappy with the move and said helmets for pillion riders are unnecessary. On May 25, the police commissioner had instructed traffic cops to take action against bikers whose pillion riders were not wearing helmets. The traffic department had given 15 days’ time to bikers for compliance, failing which they would be penalised.
