<P> French roads have a variable speed limit that depends on weather conditions . In dry weather rural 2 - or 3 - lane roads are limited to 90 km / h, 4 - lane expressways (in rural areas) 110 km / h, and highways (in rural areas, when classified as motorway) 130 km / h . When raining, the limits are lowered to (respectively) 80, 100, and 110 km / h . Urban speed limit of 50 km / h is unaffected by weather . The general speed limit is lowered to 50 km / h on all roads in the fog or other low - visibility conditions if visibility is under 50 metres . </P> <P> Vehicles over 3.5 metric tons of maximum total weight have lower speed limits . Lorries of more than 12 metric tons (except dangerous goods and trailers that may have lower limits) may not exceed 50 km / h in urban areas (even if the speed limit was raised to 70 km / h), 90 km / h on highways, and 80 km / h elsewhere . Lorries under 12 metric tons but over 3.5 have the same limits except 90 km / h on 4 - lane expressways . Buses may not exceed 100 km / h on highways and 4 - lane expressways . </P>
