Using or holding a mobile phone while stopped at a red light is a traffic violation punishable by a maximum fine of up to 4,000 baht. Additionally, 1 driving performance point will be deducted pursuant to Section 43(9) of the Road Traffic Act, which prohibits drivers from using mobile phones while operating a vehicle.
However, if a call is necessary, drivers must use hands-free devices—such as earphones, Bluetooth headsets, or the vehicle’s speakerphone system—and must strictly refrain from holding or touching the phone by hand.
