The Thai Cabinet has approved new regulations governing speed limits on the Don Muang Tollway (Concession Highway No. 5) on Tuesday.
The Ministerial Regulation on Determining the Speed Rate of Vehicles on Concession Highways B.E. 2020 aims to improve traffic flow and enhance safety on this vital thoroughfare.
Previously, the Don Muang Tollway lacked specific speed limit regulations. While the Ministerial Regulation on Speed Limits for Driving in Bus Lanes B.E. 2564 provided general guidelines, it was not deemed suitable for the specific characteristics of a concession highway.
The new regulations introduce the following speed limits:
- Trucks (over 2,200 kg) and passenger buses: 80 km/h (previously 60 km/h)
- Vehicles towing other vehicles: 65 km/h (previously 45 km/h)
- School buses: 80 km/h (previously 60 km/h)
- All other vehicles: 100 km/h (previously 80 km/h)
Furthermore, vehicles in the rightmost lane must maintain a minimum speed of 90 km/h, unless traffic conditions or visibility restrictions necessitate a lower speed.
