New Delhi: Drivers who don't fix their FASTags on the windshield of their vehicles will face permanent blacklisting of tags, a measure taken in view of the malpractice of people handing out "loose or unfixed tags" for payment of highway-user fee, which leads to congestion at toll plaza lanes.

The NHAI company dealing with toll collection and management of highways, IHMCL, has asked federations of toll collectors, highway builders and operators to report such cases for quick action. "Tags-in-hand" have been categorised as "loose tags".

Despite repeated advisories against the practice there have been several cases of people handing out FASTag at toll gates for deduction of user fee.
