What is the primary purpose of variable message signs situated on roads?

Question

DentroTest · Accepted Answer

Variable message signs (VMS) are electronic signaling devices designed to manage traffic dynamically. Their main purpose is to provide real-time information to drivers about what is happening on the road (accidents, roadworks, fog, or congestion) to increase safety and flow.  While these panels can also display regulatory signs (such as speed limits or prohibitions) and warnings, the correct answer encompasses their essential communicative function. They should not be confused with 'stop' signs (they do not require stopping at the panel), nor is their sole function to restrict; they also inform and advise.
