Argentina is to begin testing technology that displays a video feed on the back of a truck to allow cars to check whether it is safe to overtake.

Samsung’s “safety truck”, a tie-up with Volvo, has finished four months of testing and will now make it onto public roads in Argentina.

It equips a truck with two front-facing cameras and four large panels on the back, which form one big display when the rear doors are closed.

The display shows a real-time feed of what is up front, allowing drivers behind the truck to “see through” it and determine whether it’s safe to overtake. Samsung says the cameras are capable of capturing clear video even at night time.
