A driver intention estimation arrangement configured to estimate a level of overtaking intention of a driver of a vehicle hosting the arrangement, the arrangement comprising; - a driver eye monitoring unit (7.1, 7.2) configured to monitor a gaze direction (g) of at least one eye of the driver, and - a processing unit configured to analyse the gaze direction (g), where the processing unit is further configured to estimate the level of overtaking intention on the basis of the gaze direction (g), characterized in that, the analysis of the gaze direction (g) involves a determination of whether the gaze direction (g) of the at least one eye of the driver is towards a rear view mirror (11.1, 11.2) on more than one occasion during a predetermined time period, and where the processing unit is further configured to estimate the level of overtaking intention on the basis of this determination, and where the arrangement further comprises at least one of the following: a pedal sensor, configured to sense positions of an accelerator pedal of the host vehicle, and where the processing unit is configured to analyse a pattern of accelerator pedal activity, and where the processing unit is further configured estimate the level of overtaking intention on the basis of the pattern of accelerator pedal activity; a distance sensor (15.1, 15.2), configured to measure a distance (d) to a preceding vehicle, and where the processing unit is further configured to estimate the level of overtaking intention on the basis of at least one of the measured distance (d) to a preceding vehicle and a rate of change of the measured distance (d) to a preceding vehicle; and a lane position sensor, configured to measure a lateral position (p) of the host vehicle in a current vehicle lane, and where the processing unit is further configured to estimate the level of overtaking intention on the basis of at least one of the measured lateral position (p) of the host vehicle in the current vehicle lane and a rate of change of the measured lateral position (p) of the host vehicle in the current vehicle lane. - a driver eye monitoring unit (7.1, 7.2) configured to monitor a gaze direction (g) of at least one eye of the driver, and - a processing unit configured to analyse the gaze direction (g), where the processing unit is further configured to estimate the level of overtaking intention on the basis of the gaze direction (g), characterized in that, the analysis of the gaze direction (g) involves a determination of whether the gaze direction (g) of the at least one eye of the driver is towards a rear view mirror (11.1, 11.2) on more than one occasion during a predetermined time period, and where the processing unit is further configured to estimate the level of overtaking intention on the basis of this determination, and where the arrangement further comprises at least one of the following: a pedal sensor, configured to sense positions of an accelerator pedal of the host vehicle, and where the processing unit is configured to analyse a pattern of accelerator pedal activity, and where the processing unit is further configured estimate the level of overtaking intention on the basis of the pattern of accelerator pedal activity;
