Apple (AAPL) and Google (GOOG) may be working on cars and self-driving vehicles, but Samsung has its focus set on semi-trailers, unveiling the Samsung Safety Truck, a custom big rig equipped with a camera and four TV monitors that allow drivers who are following to see through the 18-wheeler.

Samsung created the Safety Truck as a way to make driving behind an 18-wheeler a less dangerous task. By putting a wireless camera on the front end of a semi-trailer and monitors on its back end, Samsung can show drivers cruising behind the Safety Truck what lays ahead.

"This allows drivers to have a better view when deciding whether it is safe to overtake. Another advantage of the Safety Truck is that it may reduce the risk of accidents caused by sudden braking or animals crossing the road," Samsung said in a blog post. You can see the Samsung Safety Truck in action in the video at the bottom of this post. 

The South Korean company said it tested the Samsung Safety Truck in Argentina, which has a high number of two-lane roads that are frequented by semi-trailers. To test the Safety Truck prototype, Samsung teamed up with a client in the South American country. The company is now working with Argentina's government and non-governmental organizations there so that the Samsung Safety Truck can comply with all protocols and receive any necessary permits and approvals.
