In normal conditions, there is a minimum speed of in the leftmost lane. There is no minimum speed on the others lanes, however the speed must be adapted to the conditions and not constitute a hazard by being too low. Safe design The autoroutes are designed to increase driver safety and allow for higher speed limits () than on regular roads () without increasing the risk of accidents. The safety features include: one way driving: the lanes driving in the opposite direction are separated by at least a crash barrier designed to resist the oblique impact of a car at up to ; there are no intersecting roads but overpasses and underpasses; wider carriageways, with at least 2 (often 3) lanes driving in the same direction, with a larger turning radius - some recently built autoroutes have one-lane-only sections; for privately operated motorways, in 2017, the proportion is 6800 km (74%) in 2x2 lanes, 2252 km (25%) in 2x3 lanes, 84 km (1%) in 2x4 lanes.
