As talked about, all electrical vehicles registered as new are obliged to offer these tools, whereas fashions already accepted must adapt by 1 July 2021. For some fashions, it will likely be sufficient to replace a software program, whereas for different electrical vehicles you’ll have to set up a brand new {hardware}.

The measure goals to enhance the security of electrical vehicles (for whose buy-in Italy there are incentives and eco-bonuses) and stop accidents doubtlessly brought on by the silence of those vehicles. which makes it tough for pedestrians, cyclists, and much more so for the blind to note their transit.
