A vehicle driver assist arrangement includes a processor configured to receive road profile data representative of a road profile in front of the vehicle and to receive current vehicle velocity data representative of a current velocity of the vehicle. The processor processes the road profile data to detect if the road in front of the vehicle contains a hidden or at least partially hidden curve, and to communicate with a user interface to issue a warning if a hidden or at least partially hidden curve is detected and the current vehicle velocity exceeds a threshold velocity.
