Confusion on M81 Motorway Spurs Safety Measures
Bang Yai, Thailand – Drivers using the M81 motorway between Bang Yai and Kanchanaburi have reported confusion due to unclear signage, prompting the Department of Highways to implement a series of corrective measures aimed at improving navigation and safety. The concerns have arisen since the motorway opened, as motorists frequently struggle to distinguish the correct lanes and entry points, especially near major intersections and access points.
The Department of Highways has initiated the installation of more visible road signs and pavement markings at key entrances, exits, and junctions. These measures are intended to guide drivers more clearly, reducing the risk of wrong turns onto the motorway. Additionally, authorities are coordinating with online navigation services to ensure that maps reflect accurate entry and exit points, operating hours, and any temporary restrictions, helping drivers plan their routes effectively.
For motorists who inadvertently enter the motorway, the department advises exiting at Nakhon Chai Si, then using Route 3233 to return to the M81 heading toward Bang Yai—a detour that adds approximately 15 minutes to the journey.
Analysis from Transport Daily News and AI commentary by ChatGPT highlights several contributing factors. Signage is sometimes placed too close to junctions, giving drivers limited time to make decisions. Certain lanes resemble secondary roads, which can mislead drivers into taking the wrong route. Furthermore, there is limited space for motorists to safely check maps or GPS devices before entering the motorway.
Proposed solutions include the installation of advance directional signs at least 500 meters to 1 kilometer from junctions, color-coded motorway signage with the M81 logo, and the updating of Google Maps and other navigation tools to reflect the correct lane configurations. Additional road markings, such as chevron patterns and directional arrows, are recommended to enhance visibility, particularly at night.
Officials involved in implementing these changes include representatives from the Department of Highways, with collaboration from navigation service providers and contributions from local transportation experts.
