The red, green and yellow stickers that emergency and essential service vehicles need to sport as part of an initiative to curb traffic on Mumbai roads during the ‘break the chain’ restrictions will have to be prepared by vehicle owners and won’t be provided by the police, an official said on Sunday.

Under the initiative, vehicles belonging to doctors, medical staff, ambulances and those engaged in supplying medical equipment will have to sport red stickers, and those transporting food, vegetables, fruits, groceries, dairy products, etc, will use green stickers.
