The pedestrian crossing that Dr Waraluck "Kratai" Supawatjariyakul died on while hit by a policeman (out of uniform) who was riding a "superbike" is right in front of my Condo. Kratai used to live in the same building. That crossing now has traffic lights to stop traffic while you cross.
Pedestrian crossings in Thailand do not have the same "road rules" as in western countries. Stand at a pedestrian crossing without traffic lights in Thailand waiting to cross and it's up to motorists to decide whether they want to stop or not. Overseas it is commonly compulsory, by law, to stop. And in Thailand, even if a car, or cars have stopped there's always the chance a motorcyclist comes whizzing though those stationary cars.
My attitude in Thailand while crossing a road in Thailand is always give way to motorists whether your at a pedestrian crossing or not. If you don't do this you may be the party to lose out, maybe with your life.
