Mandatory minimum speeds by motorway lane

The green motorway sign shows three lanes. The figure 90 beneath the left lane and 60 beneath the centre lane are mandatory minimum speeds for using those lanes; the right lane has no additional minimum shown. A vehicle travelling at 100 km/h may use the centre lane, while one travelling at 50 km/h must remain in the right lane. The figures are neither advisory nor maximum speeds, and a vehicle travelling at 80 km/h may not use the left lane because it cannot meet that lane's 90 km/h minimum.
