DMT, the operator of the Donmuang tollway, has waived all tolls from 14:30 on 26 September until 24:00 on 27 September 2026 because of flooding on Vibhavadi Rangsit Road. Light vehicles should avoid the Chaeng Watthana (inbound), Lak Si (outbound) and Lat Phrao (outbound) toll gates, where flooding is deep and only large vehicles can pass. If your staff or deliveries use this route, plan the trip around the flooded gates and expect the free road to be busy.
