Ewaybill

You can extend the validity .Suppose the avidity of the e-waybill expires on  17/02/2019 then the validity can be extended from 4 pm of 17/02/2109 to 8 am of 18/02/2019. Even the transporter can increase the validity of the e_waybill. It can be done through www.ewaybill.nic.in

If the validity is already expired then it will be wise not to move the vehicle with expired e_waybill. It will be better to approach to the authority to extend the validity.
