A vehicle (3) driver assist arrangement (1) is provided. The arrangement (1) comprises processing means (5), road profile input means (7), current vehicle velocity input means (9), and a user interface (11). The processing means (5) is arranged to communicate with the road profile input means (7), the current vehicle velocity input means (9) and the user interface (11). The processing means (5) further being arranged to receive road profile data representative of a road profile in front of the vehicle (3) from the road profile input means (7), and to receive current vehicle velocity data representative of a current vehicle velocity of the vehicle (3) from the current vehicle velocity input means (9). The processing means (5) are still further adapted to process the road profile data to detect if the road (13) in front of the vehicle (3) contains a hidden or at least partially hidden curve (15). The arrangement (1) is adapted to issue a warning, via the user interface (11), if a hidden or at least partially hidden curve (15) is detected and if the current vehicle velocity exceeds a threshold velocity. The invention also relates to a vehicle (3) comprising a vehicle driver assist arrangement (1) and a method of assisting a driver of a vehicle (3).
