The new regulation passed in mid-August, but starting today everyone—even passengers in the backseat—need to buckle up or face a 2,000 baht fine. 

Kids six and under get a reprieve until Dec 4 allowing for the purchase of affordable children’s seats. Authorities have said that they will begin enforcing the law by issuing warnings rather than fines at first, until the law is more widely known, and fines will be at the discretion of the police officer. 

These new regulations follow a host of other penalty hikes, including increasing speeding fines, raising the fine for not stopping at a crosswalk from B1,000 to B4,000, and the fine for bikers not helmeting up is now B2,000 rather than B500. 

Earlier this year, the death of 33-year-old Waraluck “Doctor Kratai” Supawatjariyakul, who was struck by a motorcycle cop at a crosswalk and killed, was followed by public outcry for more safety on Bangkok’s roads. Last year, more than 600 people died on roads in Bangkok, and more than 70,000 were seriously injured.
