A safety stoppage device (1) for an autonomous road vehicle (2) having control networks (11) and sensors (12), and an autonomous drive-control unit (13) for processing sensor- and communication-signals and providing control signals for lateral and longitudinal control. A primary brake-control unit (4) is arranged to monitor the longitudinal control signals for faults and upon determination of a such fault arranged to execute a longitudinal control profile, stored independent from the autonomous drive-control unit (13), to perform braking to a stop. A primary steering-control unit (8) is arranged to monitor the lateral control signals for faults and upon determination of a such fault arranged to control a primary steering actuator (9) to follow a lateral control trajectory, stored independent from the autonomous drive-control unit (13), and, if not already triggered, simultaneously trigger the primary brake-control unit (4) to execute the stored longitudinal control profile to control wheel brakes (6) to perform braking to a stop during execution of the lateral control trajectory.
