Outside any major construction site in Tokyo, you will find a noise meter. I assume it is required by law and penalties are steep. The basis for my assumptions? Each time that I saw an enormous lorry approach a work site, the whole "welcoming" crew was very tense. Literally, the driver attempts to coach the lorry with the bare minimum amount of sound -- no revving the engine or changing gears. Also, I rarely heard the "back up beeps" because they will surround the truck with people in yellow safety vests. Plus, one or more people might be spraying tyres to reduce dust. It is quite a ballet to watch!
