Claim:
A method for preventing overturning a dump vehicle ( 1 ), which comprises a forward vehicle section ( 2 ) with a forward frame ( 3 ) and a wheel axle ( 4 ) supported by the rear frame, a rear vehicle section ( 7 ) with a rear frame ( 8 ) and at least one wheel axle ( 9 , 10 ) supported by the frame, and an articulation joint ( 21 ), which connects the forward frame ( 3 ) and the rear frame ( 8 ) and allows the forward frame and the rear frame to pivot in relation to each other about an axis extending in a longitudinal direction of the vehicle characterized in, during a tilting procedure for unloading material from a container ( 11 ) of the dump vehicle, determining if there is a risk for a pair of wheels of the wheel axle ( 4 ) of the forward vehicle section ( 2 ) to loose ground contact or if said pair of wheels have already lost ground contact, and establishing a warning signal for preventing an uncontrolled rotation of the forward vehicle section ( 2 ) relative to the rear vehicle section ( 7 ) via the articulation joint ( 21 ) when it is determined that the wheels of the forward wheel axle has lost or is about to loose ground contact.
