A white portrait sign with a fluorescent yellow-green house-shaped panel at the top showing two black walking figures, one large and one small. Below it is the text "MAXIMUM 40", "km/h" in white on a black bar, "WHEN FLASHING", a black line, then "AU CLIGNOTEMENT". An amber round light sits at each side of the sign.
When the yellow lights on this sign are flashing, what should you do?
