Efforts to measure truck axle weights at normal highway speeds by a single scale installed in the road are ineffective because of the dynamic load variations on the axle. The extended measurement distance required to average out load variations is in conflict with the layout of axles on typical trucks. As a consequence, multiple weight sensors are required. The performance of multiple-sensor weight-in-motion systems are evaluated measuring the load of 95 axles on 21 simulated trucks. A three-sensor system appears capable of measuring loads on axles with leaf-spring and some air-spring suspensions to an accuracy of 5 to 8 percent on most roads. Measurement of axles with poorly damped wheel-hop resonance modes is much less accurate, with errors on the order of 15 percent.
