Police traffic checkpoints are a nuisance to motorists and have proved to be useless in tackling the problem of road accidents. Police traffic checkpoints are still routinely set up but only the usual suspects -- pickup trucks and motorcycles -- are targeted. People are as interested in the number of road accidents and casualties as they are anticipating festival fun. Statistically, the number of fatal casualties from road accidents during the so-called seven dangerous days at Songkran or New Year hovers around 300+ to 400+. In the 2015 report, the reported number of road traffic deaths in Thailand was 13,650.
