BANGKOK– Drivers in Thailand have one last deadline to remember. The Royal Thai Police say March 31 is the final day of the warning-only period for traffic violations. From April 1 , police will enforce the law across the country and issue fines instead of verbal warnings.
This move is part of a three-step road safety plan meant to reduce crashes. Up to now, police have focused on public education, reminders, and warnings. Starting next month, that approach shifts to stricter enforcement against the driving habits most often tied to serious accidents.
Why Police Are Tightening Traffic Enforcement
The Royal Thai Police, including Pol Gen Samran Nualma, deputy commissioner-general and head of the Traffic Management Centre , have said the goal was to help drivers build better habits before penalties began.
Since January 2026, officers have recorded more than 196,028 warnings through the Police Ticket Management (PTM) system. Those warnings created a digital record of violations without issuing immediate fines.
In other words, authorities gave drivers time to adjust. At the same time, public awareness efforts asked people to follow traffic laws for their own safety and for everyone else on the road.
Still, the road toll remains severe. During the 2026 New Year holiday period, often called the “Seven Dangerous Days” from December 30, 2025, to January 5, 2026, Thailand recorded 1,511 crashes, 1,464 injuries, and 272 deaths.
Those figures came from the Road Safety Directing Center and the Department of Disaster Prevention and Mitigation. Speeding, drunk driving, and sudden lane-cutting ranked among the leading causes. Bangkok and busy tourist areas such as Phuket were hit especially hard.
Because of those numbers, police are moving into Phase 2. Authorities say warnings alone haven’t done enough. From April 1, officers will focus on 10 major traffic offenses that are often linked to deadly and high-risk crashes. The message is clear: change your driving habits now or pay the price.
What Changes on April 1
Phase 1 ends tomorrow. After that, police will take a no-nonsense approach to dangerous traffic violations.
Officials have not published the full list of 10 offenses in every statement. However, reports have repeatedly pointed to the same high-risk violations. These include:
- Speeding, on highways, city streets, and rural roads
- Drink-driving (DUI), including cases involving alcohol or drugs, and refusal to take a breath test
- Unsafe lane changes or cutting in suddenly, especially when those moves put other drivers at risk
- Not wearing a helmet, for motorcycle riders and passengers
- Running red lightsor ignoring traffic signals
- Driving without a valid licenseor using an expired one
- Using a mobile phone while driving
- Failing to give wayto pedestrians or other vehicles at intersections
- Illegal overtakingor passing in unsafe areas
- Vehicle defects, including excessive black smoke and unsafe modifications
Police say these are not small mistakes. They are common factors in many serious crashes. Officers will also use the PTM system to document violations, issue fines, and apply demerit points where required. Drivers who already received warnings during the grace period could face tougher treatment if they break the rules again.
Traffic Fines and Penalties From April 1, 2026
The exact fine can differ based on the offense, the location, and whether the driver has committed the same violation before. Still, Thailand’s Land Traffic Act sets the basic penalty ranges. Here is what drivers may face under stricter enforcement:
- Speeding: usually fines of 1,000 to 4,000 baht, plus demerit points. Higher speeds, or speeding near schools and hospitals, can lead to heavier penalties.
- Drink-driving: a first offense often brings fines of 5,000 to 20,000 baht, possible jail time of 6 to 12 months, and license suspension for at least six months. Repeat offenses can bring much larger fines, longer jail terms, or even permanent license revocation. Refusing a breath test is treated the same way.
- Not wearing a helmet: around 2,000 baht for the rider or passenger.
- Running red lights or ignoring signals: up to 4,000 baht.
- Using a phone while driving: generally 1,000 to 2,000 baht, plus demerit points.
- Driving without a valid license: around 1,000 to 2,000 baht or more, and the vehicle could be impounded in some cases.
- Dangerous lane changes or illegal overtaking: about 1,000 to 4,000 baht, depending on the risk involved.
In more serious cases, drivers may also face court action, vehicle seizure, or mounting demerit points that can lead to a suspended license. If a traffic violation causes a crash, the legal trouble can grow quickly, including possible criminal charges.
Authorities say these penalties are meant to protect everyone on the road, from local families to tourists and daily commuters.
What Drivers Should Do Now
With only a short time left before full enforcement begins, police are urging drivers to act right away. Check your driving habits. Make sure your vehicle is road-safe. Confirm that everyone in the car wears a seat belt, and that every motorcycle rider and passenger wears a helmet. Leave early so you don’t rush, and never drive after drinking.
The rules apply to everyone, including tourists and expats in places like Bangkok, Phuket, and Chiang Rai. In addition, rental companies may face closer checks on vehicle condition and safety standards.
This three-phase plan shows that police started with awareness and are now moving into strict enforcement. A third phase could add more steps later. For now, though, April 1 is the key date.
National police commissioner Pol Gen Kittirat Phanphet has backed the policy as part of a wider effort to change road behavior. Deputy spokespeople have also called on the public to cooperate.
Road safety is not only a police issue. It depends on every person using the road. Small choices behind the wheel can stop the kind of loss seen over the New Year holiday.
As March comes to a close, the countdown is nearly over. Drive carefully, stay alert, and remember, after tomorrow, the warnings end.
