When, according to the invention, a thermochromic pigment is added to a generally known road marking basic material, road markings may be established with integrated warning effect in the form of a colour change which is produced at temperatures below 5° C. This marking material may be used for road stripes ( 2 ), points and other markings, just as it may be used for the production of colour changing flat elements ( 3, 4 ).
