For drivers navigating Thailand’s congested highways during the 2026 holiday season, relief is coming in two distinct waves. Government agencies have confirmed a dual-tier fee exemption plan designed to ease traffic during Chakri Memorial Day and the Songkran New Year festival, though the details depend heavily on which road you take and when you travel.
The announcement splits the benefit between two major public holidays. On April 6, commemorating Chakri Day, toll fees will be waived across three specific expressway routes encompassing 63 plazas. Later in the month, during the Songkran festival, the Department of Highways will open five major motorways for free leverage over a seven-day period. It’s a significant logistical move, but one that requires travelers to understand the difference between the country’s expressway and motorway systems to avoid unexpected costs.
Two Holidays, Two Systems
Confusion often arises because different agencies manage the roads. The Expressway Authority of Thailand (EXAT) is handling the Chakri Day exemption. Their waiver applies strictly to April 6 and covers three urban expressway lines. This is a targeted one-day relief effort aimed at reducing congestion within the metropolitan corridor during the public holiday.
The Songkran exemption is broader in scope but operates under a different authority. The Department of Highways is managing a seven-day free passage window on five intercity motorways, identified as M7, M9, M81, M6, and M82. This distinction matters for planning. A driver leaving Bangkok for the provinces during Songkran will likely benefit from the Department of Highways waiver, while a commuter staying within the city limits during Chakri Day will rely on the EXAT exemption.
The Logistics of Relief
Public infrastructure waivers are rarely just about goodwill; they are traffic management tools. By removing toll barriers financially, agencies encourage flow through specific corridors that can handle the volume. The seven-day window for Songkran is particularly notable. It covers the peak travel period when millions of residents return to their hometowns, a tradition that historically strains interprovincial routes.
Though, the split administration means there is no single “free travel” switch for the entire country. Drivers transitioning from an EXAT expressway to a Department of Highways motorway during the Songkran period need to verify their specific route segments. While the motorways M7 through M82 are cleared for free passage, connecting urban expressways may still incur charges unless specifically listed in the EXAT waiver.
Planning Ahead for 2026
With the announcements set for the 2026 calendar year, travelers have ample time to adjust their budgets and routes. The specificity of the route codes—M7, M9, M81, M6, M82—suggests a focus on high-volume arteries that typically witness the worst bottlenecks. For regular commuters, the April 6 exemption offers a brief respite, but the Songkran window provides the substantial economic benefit for long-distance travel.
As with any major policy shift, implementation details such as eligible vehicle classes and exact start times should be monitored closer to the dates. Agencies often release technical guidelines shortly before the waiver period begins to ensure toll booth operators and automated systems are aligned. For now, the framework is clear: two holidays, two agencies, and a coordinated effort to preserve traffic moving.
Which roads are covered on April 6?
The April 6 exemption covers three expressway routes managed by EXAT, totaling 63 toll plazas. Specific route names were not detailed in the initial announcement, but they fall under the urban expressway network.

How long does the Songkran free period last?
The Department of Highways has scheduled a seven-day full waiver for the Songkran period. This covers five major motorways designed for interprovincial travel.
Does this apply to all vehicles?
While most public holiday waivers in Thailand apply to standard passenger vehicles, specific restrictions on heavy trucks or specialized transport may still apply. Drivers should verify vehicle class eligibility closer to the travel date.
Have you found that holiday toll waivers significantly change your route planning, or do you stick to your usual roads regardless of the cost?
