Soon, yellow lines at toll plazas will ensure that the waiting queue of vehicles is not more than 100 metres at any given point of time and if the queue is beyond the stipulated distance, then vehicles at the front can pass without paying the toll. These guidelines have been issued by the National Highways Authority of India (NHAI) as it seeks to minimise waiting time at toll plazas and ensure service time of not more than 10 seconds per vehicle even during peak hours.

Noting that although at most of the toll plazas, there is no waiting time after the mandatory 100 per cent FASTag, the NHAI said, "even then if there is a queue of waiting vehicles of more than 100 metres due to some reason, the vehicles will be allowed to pass without paying toll till the queue comes within 100 meters from the toll booth".
