The Minnesota Department of Transportation
hoped that they could measure the weights of big trucks without
actually stopping the vehicles by using a newly developed
“weight-in-motion” scale. To see if the new device was accurate,
they conducted a calibration test. They weighed several stopped
trucks (Static Weight) and assumed that this weight was correct.
Then they weighed the trucks again while they were moving to
see how well the new scale could estimate the actual weight.
