สินค้าเกินขนาด Requirements in Thailand
สินค้าเกินขนาด transport in Thailand is subject to strict regulations governing dimensions, weight, route planning, escort requirements, and ใบอนุญาตขนส่งพิเศษ procedures. These regulations exist to protect road infrastructure, ensure public safety, and minimize traffic disruption. Requirements can vary significantly between regions (Bangkok Metropolitan, Eastern Seaboard, Central, Southern), so operators must verify specific rules for each jurisdiction their route passes through.
Dimensional Limits
Standard dimensional limits in Thailand define the maximum width, height, length, and weight a vehicle can be before it's classified as an สินค้าเกินขนาด. Typical thresholds are: Width: 2.5–2.6 metres, Height: 4.0–4.3 metres, Length: 18–23 metres (for semi-trailers). Loads exceeding these dimensions require a ใบอนุญาตขนส่งพิเศษ and may need one or more รถคุ้มกัน vehicles depending on the degree of excess.
ใบอนุญาตขนส่งพิเศษ Process
To transport an สินค้าเกินขนาด in Thailand, you must obtain a ใบอนุญาตขนส่งพิเศษ. The application typically requires: exact load dimensions and weight, proposed route with alternatives, transport date and time window, proof of insurance, vehicle specifications, and escort arrangements if required. Processing times vary from 24 hours to several weeks depending on the load classification and number of jurisdictions involved.
Escort Requirements by Load Size
Thailand typically requires escorts based on load dimensions: loads up to moderate oversize may need a single front รถนำ, larger loads require both front and rear escorts, and สินค้าเกินขนาดพิเศษ classification may require police escort in addition to private รถคุ้มกัน vehicles. Some jurisdictions also restrict travel to specific times (typically early morning or off-peak hours) and prohibit movement during holidays or severe weather.
