An arrangement and a method are described for safeguarding driver attentiveness to the task of steering while operating a vehicle having a lane keeping aid system. The arrangement and method provide for measuring a pinion angle and a torsion bar torque when the lane keeping aid system is applying an overlaying steering torque. Driver applied torque is estimated from the measurements. A hands-off metric is calculated based on a relation between the measurements and the estimate. Hands-off is determined based on a comparison of the metric with a predefined threshold. The arrangement and method further provide for evaluating hands-on between torque interventions by the lane keeping aid system. An action is determined based on the determined hands-off and the evaluated hands-on and the action determined performed.
