Truck drivers?

So, I don’t know about anyone else, but I always worry and hear about how truck drivers have blind spots and there are constant accidents with them. Like do 18-wheeler style trucks use cameras usually to make up for this? I have a front/back camera from a company called beautyfromife that sells on Amazon for cheap. So if they don’t have them, I think they should get one. I think they should be standard on those big trucks. I often wonder if they have some sort of safety net like this or not....
