No truck driver should drive without a dash cam. Not anymore. They are now relatively cheap (less than $100.00) and provide piece of mind in a variety of unfortunate events.
Unfortunately there is currently no company that makes a dash cam specifically for truckers. Why? Because there is no need to. All dash cams are essentially the same. It doesn’t matter if you are driving a tractor trailer, box truck, bus, car, or pickup truck, dash cams all do the same thing; they record while you are driving.
