A safety stoppage device for an autonomous road vehicle having at least one control network and sensor, and an autonomous drive-control unit for processing sensor and communication signals and providing control signals for lateral and longitudinal control. A primary brake-control unit is configured to monitor the longitudinal control signals for faults and, upon determination of a fault, execute a longitudinal control profile, stored independent from the autonomous drive-control unit, to perform braking to a stop. A primary steering-control unit is configured to monitor the lateral control signals for faults and, upon determination of a fault, control a primary steering actuator to follow a lateral control trajectory, stored independent from the autonomous drive-control unit, and, if not already triggered, simultaneously trigger the primary brake-control unit to execute the stored longitudinal control profile to control wheel brakes to perform braking to a stop during execution of the lateral control trajectory.
