Some one is a Genius!! So much more opportunities for safer more enjyable driving with this technology. Needed at blind corners etc.

Not a bad idea. I just hope it won't be too distracting for the drivers behind them. Just imagine, going down the road and see a truck with a huge monitor hanging on it. Would you be like, "oh...how convinient?" or will you be more like, "omg....there is a tv hanging on the truck!"

I see a liability issue if someone doesn't, or claims not to have, seen an oncoming vehicle despite this.

Brilliant idea, a useful application of technology. Hope they address auto control of the brightness of the display, otherwise at night drivers could pull out to overtake and find their night vision is at zero!!!! How long before some thrusting young exec. starts selling the space for advertising?

I hate to share the road with trucks. It's unsafe, inconvenient, and I have missed my offramp because they blocked the view. Without a govt. monopoly on the highway system I believe some expressways would be dedicated to commercial vehicles, some private vehicles.
That said, Samsung could provide a much needed product to save lives. A "heads up" display complete with the speed/distance of an oncoming vehicle, and a realistic recommendation of needed passing speed to avoid a collision would take out the guess work.

Until it lags and someone gets hit head on. Or someone is too busy watching the screen and rear-end the tractor and trailer.

Needs to operate at all temperatures and the rear spray off the wet roadway onto the back of the truck would cover the monitors in seconds., if not obliterating the view, as so with the font mounted camera from the previous vehicle. Lots more to consider before parading an idea around as viable.

@Don Duncan
Aside from the rear bumpers that decapitate you if you rear-end 'em, I don't have any issues with sharing the road with semis.
In my experience, truck drivers are careful to make their lane-changes and very predictable on the road. (likely because their career is KAPUT if otherwise). Once they automate trucks and fix their rear bumpers, I think trucks on the road would actually make the roads safer.

Don Duncan, one step at a time. Sometimes people forget
Bob Flint, keeping the monitor clean is no mystery. We've done it for years now. The placement of the trailers back doors in relation to the sidewalls is the key. We've all seen car drivers who are attempting to find the sweet spot within the turbulence where there is virtually no buffeting and the car is literally riding the trucks 'draft'. The cars windshield remains relatively clean. Let the aerodynamic forces do the grunt work. You might be surprised how clean the trailer doors remain even in the hardest rain. Keeping the screen clean is the most basic and least important issue here. There are essentially two door systems currently in use - center latching and roller-style. Roller-style takes a solid panel that is cut into slats and then be reliably reassembled into what will appear to be a single, solid slab.?

Nice idea in theory except for a few little drawbacks.
1) No owner operator or very few businesses will pay for something that doesn't benefit them. If it doesn't save or make money for them it doesn't make sense.
2) How many people will focus on the screen and not on the road if they're behind a truck. Looking in the wrong direction can get them killed just as much as a head on.
3) The trucks that come in from out west at work have been driving sometimes for days and you can't even read the long vehicle signs on the back because of the red dirt all over them. Trying to look at a super size monitor covered in bulldust won't be very effective.
Otherwise a cutsey little idea for countries with no dirt roads and nice clean highways.
