I used to work for a data provider in Lebanon, NH, Teleatlas North America, that was eventually taken over by TomTom. The capability to put this information in GPS apps has long existed, but the companies that buy the data need to keep that data updated. Even Google Maps or Apple Maps have the capability. They can be fed cloud based traffic data. This would be easy.

But the truckers have to have an updated version of whatever software they use on whatever device they use. It's not the tech necessarily. It's user error, neglect, or ignorance, very often.
