The new rules also impose a speed limit of 40 kilometres/hour on two-wheelers with children as pillion riders.
The Motor Vehicles Act has been amended to introduce these rules, which will come into force a year from now.
Safety harnesses will be worn both, by the rider and the pillion, allowing for children to be securely attached to the rider.
According to the new rules, safety harnesses need to be lightweight, durable, made from nylon, with the capacity to hold weight up to 30 kgs, the notification said.
Children will also be required to wear standard two-wheeler safety helmets or bicycle helmets while riding pillion.
In October 2021, the ministry had proposed to change the motor vehicle rules to bring in new safety measures for two-wheelers carrying children.
