A remote non-contacting vehicle load and emissions compliance monitoring system includes a remote vehicle velocity detector, a remote emissions temperature sensor, a remote emissions content monitor, and a processing and computing unit connected to receive data from the sensors and compute the vehicle load based on the vehicle velocity and emissions temperature, as well as on road and environmental conditions and stored vehicle operating specifications, and to compare the observed exhaust plume content with a model emissions profile based on the computed load and vehicle characteristics.
