It’s essential to towing a car legally and ask for help (ขอความช่วยเหลือ which is the term in Thai) to avoid fines and losing points, but towing it safely is even more important. To do this, both the tracing vehicle and the trailer or towed vehicle must meet certain requirements, and, in each case, the driver must act correctly. The accessories used for this purpose must also be suitable. For example, tow hooks are suitable for pulling trailers of a certain weight. Approved hitches must meet specific requirements in terms of attachment points, dimensions, height, the distance between ball and bumper, pass the corresponding dynamic life test and carry a corresponding approval number.
To ensure that we act with the utmost safety and within the law, we will review these and other concepts related to towing a car with another or towing trailers.
Legal Requirements For Towing A Car Or Trailer
To drive according to the law and avoid complications, it is essential to know that different driving licenses allow you to carry specific loads. The maximum mass that a vehicle can have on public roads once it is loaded is called the Gross Vehicle Weight (GVW):
With the B license, you can drive vehicles with a GVW of up to 3,500 kg and light transport trailers with a maximum authorized mass of up to 750 kg. The total weight of all vehicles must not exceed 4250 kg. The B-96 extension of this license allows the driving of trailers over 750 kg, provided that the total mass of all vehicles does not exceed 4250 kg.
With the B+E license, you can drive a combination of vehicles with a total laden weight (PTAC) of more than 4250 kg. You must pass a test for driving heavy trailers to obtain this license.
The C+E heavy goods vehicle license is required when all vehicles exceed 7,000 kg.
