Weigh In Motion
Weigh-in-motion or Weighing in Motion (WIM) devices are designed to capture and record axle weights and gross vehicle weights as vehicles drive over a measurement site. Unlike static scales, WIM systems are capable of measuring vehicles traveling at a reduced or normal traffic speed and do not require the vehicle to come to a stop. This makes the weighing process more efficient, and, in the case of commercial vehicles, allows for trucks under the weight limit to bypass static scales or inspection.

Famous quotes containing the words weigh and/or motion:
“I acknowledge that the balance I have achieved between work and family roles comes at a cost, and every day I must weigh whether I live with that cost happily or guiltily, or whether some other lifestyle entails trade-offs I might accept more readily. It is always my choice: to change what I cannot tolerate, or tolerate what I cannot—or will not—change.”
—Melinda M. Marshall (20th century)
“We must not suppose that, because a man is a rational animal, he will, therefore, always act rationally; or, because he has such or such a predominant passion, that he will act invariably and consequentially in pursuit of it. No, we are complicated machines; and though we have one main spring that gives motion to the whole, we have an infinity of little wheels, which, in their turns, retard, precipitate, and sometime stop that motion.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
