While they keep telling you that not everyone here obeys traffic signals, I haven’t actually felt that it was any more dangerous than NY City streets – perhaps even less so. Gotta be vigilant both places, but people are nicer here and they drive slower!
They do have a totally cool thing with traffic signals at major intersections though… Huge countdown clocks so you never have any question about when it’ll be your turn to go: 
Or how much time you have left to get through the intersection: 
That said, weirdly enough on lesser intersections with lights, there doesn’t seem to be any “green light” at all. There’s just “red” and the absence of red….
In Cambodia it seems everyone is used to the fact that everything shares the road: trucks, buses, cars, motos, water buffalo, oxen, people, dogs, chicken, bikes and more–one gets used to being a defensive driver.
