You can forget about the traffic stopping at red lights ( notably Thais ) as they don't give a damn about red lights, traffic law, pedestrian rights etc etc !
There is NIL / Nada/Zero policing and bringing offenders to justice ( the guy in the white pickup will likely blame the brakes !!)
The new driving license points system will not deter stupid !
I have seen someone mown down on 2nd road in Jomtien near the Immigration soi ! Traffic was speeding through there at a minimum 80kh with not a care in the world for what the pedestrian traffic lights show.
Yesterday I sat at Chaiyapruk crossroads on 2nd road waiting the lights to turn green . A white Fortuner whizzed by going in the lane to turn right but actually went straight on with a red light ! It's on my dashcam !!
Motorbikes just ignore the red lights .
Best advice for tourists /pedestrians - forget about lights/zebra marked crossings - use the simple rule " look right , look left , look right again and if IF clear , go ahead , cross !!! ( this is NOT Europe or the West , but the "Wild West" of Thailand !!)
