Department chief Thanin Somboon said that, since late 2016, his agency has improved equipment at its permanent and mobile truck-weighing checkpoints across the country to crack down on overloading trucks. 
The controls save money in repairing highways and preventing damage to bridges and tunnels. 
Officers had fined the operators of 4,454 overloading trucks in the fiscal year 2017 (October 1, 2016-September 31, 2017) and 2,098 overloading trucks so far in the fiscal year 2018 (October 1, 2017-February 28, 2018), he said. 
He urged cargo transport operators not to overload trucks beyond their legal capacity and warned those violating the rule will be punished with up to six months in jail or up to Bt10,000 in fines, or both.

Operators of more than 6,500 overloaded trucks fined

The Department of Highways has revealed that a total of 6,552 overloading trucks had been intercepted and operators' fined since October 1, 2016 until February 28, 2018.
