7 motorway between Pattaya and Phan Thong...... I commute daily, morning and evening I see cars/pickups/trucks/buses etc etc pulled over by the highway police.
UI do not know the details but I work for a Thai company.
We employ many from Laos.... through a labour hire company, there is a few I asked to make fulltime company employees (they damn good workers) but was told nearly impossible to employ direct.
