The Highways Agency has started to use new pictogram signs on the M42 in the West Midlands to warn drivers of upcoming hazards.
The pictograms, which will be displayed as internationally recognised symbols, will be displayed on 36 existing road-sign hoardings over the 11 mile Active Traffic Management stretch of the M42.
The five different types of pictogram will help warn drivers of dangers ahead, including accidents, congestion, snow/ice, high winds or an increased skid risk.
Highways Agency Traffic Operations Director Derek Turner said, "This is the first time we have used these latest generation signs with pictograms to get helpful and up-to-date information out to drivers."
The Active Traffic Management scheme allows motorists to drive on the hard shoulder during busy periods.
