Pavement markings are not compulsory, except on freeways, expressways and for certain special markings. These include lines completing "stop" (AB4) and "yield" (AB3a) signs, in accordance with the provisions of article 42-2 of part 3 of the IISR, and traffic light effect lines in the cases specified in article 117-4.C of part 7 of the IISR.
