Hacking programmable road signs

Thanks to KC from my MSc gang for this ..... I guess its time the transport authorities improved their security!

Many citizens might notice the construction digital road signs on theside of the road while driving, indicating important information suchas road closures or traffic delays.....These digital road signs can be easily compromised.....
