Must be a UK thing 2019 and I've never heard a truck like that in Australia!?,(reply>), Actually I've heard them many times in Australia for the past few years. I still hear beeping, but I definitely think the white-noise alarm is more common.,(reply>), I live in the UK, had a building site at the back of my house for 3 years while they were building a bunch of new housing and don't remember hearing it once. Of course it might have been going on all the time and I never even registered it but I still heard a lot of beeping trucks at stupid o'clock in the morning.,(reply>), I actually stared to hear this sound when I started to work in Australia. On one of the construction site we even had to have the horn plugged to the doors and handbrake so the horn beep if you open the door without the handbrake being properly engaged. Overall I found Australia big construction sites being way safer than french ones.
