Display maker Samsung is solving that problem in Argentina, where someone dies almost every hour in road accidents, and their solution is simple and elegant - they've replaced several of their transport links with 'safety trucks'.
Much like the technology you'll see on some coach buses, the idea is to mount a camera at the front of the vehicle to pick up a video feed of the road ahead.
But instead of feeding it to a TV screen so passengers can be bored at the scenery ahead, Samsung's trucks have four monitors affixed to the back doors, showing drivers behind them whether or not there's room to overtake.
Samsung - which makes computer monitors and the displays for Apple's electronic devices - can obviously equip its trucks with this kind of technology far more easily than the average haulier.
Still, the price of display technology is dropping all the time, and as a safety feature, this could certainly be seen further on down the road.
