When I drive down a motorway I’m always irritated by the fact that strings of giant lorries (ie trucks) occlude my view of upcoming roadside signs.
Those mounted on overhead gantries are fine, but I often miss turnoffs, because either the sign or the road itself are hidden behind a nose-to-tail fleet of freight-filled behemoths.
Today’s invention is a simple solution.
Tall lorries would be required to have a uniform road turnoff sign painted on their rear face.
Besides the turnoff symbol, an illuminated screen would be attached as shown.
This would be activated by a wireless signal from the real, hidden sign (or via GPS) so that the last truck would always be showing me the name of the town to which the next slip road leads (as well as its distance away).
