Lane support systems (LSS) are based on computer vision and they are expected to give safety benefits. However, despite the assumed technology readiness, there is still a lot of uncertainty regarding the needs of vision systems for “reading” the road and limited results are still available from in-field testing. In this framework an experimental test of LSS performance was carried out in two-lane rural roads with different geometric alignments. LSS faults in daylight and dry pavement conditions were detected on average in 2 % of the road sections, but with significant differences basing on horizontal curvature radius. Additionally, the increase of fault probability of failure to 8% was observed in road sections with a radius of less than 200 m. A curvature radius of 200 m is a relevant geometric constrain in mountain roads in which curves with a smaller radius are common.
