Jackie here. The traffic in Saigon is chaotic and insane. There are no actual traffic laws, so everyone does their own thing. Traffic lights are few and far between, and they are mostly ignored anyway. Vehicles are overwhelmingly motor scooters, motorcycles, and bicycles. There are some cars, buses, minivans and SUVs thrown into the mix.
The noise is at top level from the engines and the constant horn beeping. I think I have figured out the horn code. It can mean: watch out, I'm coming, get out of the way, leave me alone, or I am here, don't hit/squash me.
Crossing the street is a great adventure, and a test of your fear factor. There is no such thing as a break in the traffic. You must guage the volume of the traffic. When there is a change in volume, you must go for it. Keeping a steady speed is important. No running or hesitation when crossing. Those on or in the vehicles will judge your rate, and they will go around you. It works !!
