I was driving a car like that few times, with beeping when the limit was exceeded. Annoying, but informative, unless road sign was limiting vehicle mass to 10t

I was driving a car like that few times, with beeping when the limit was exceeded. Annoying, but informative, unless road sign was limiting vehicle mass to 10t and not speed to 10km/h. It was carsharing vehicle, so I didn't bother to turn it off.
