This time this #CoSoRoadSigns of Italy toot should be easier to guess, with a little hint: look at the colour
@elleci42a @researchbuzz Toll booth Ahead?
@ACG2 In fact it means that 600 metres ahead there is a motorway and on the right panel there are the categories not allowed to transit
@elleci42a Ohhh. That does make sense now. I saw the numbers beneath items on the right and thought that was the amount of toll, instead of fine for traversing the motorway.
