Trucks can be weighted by two methods. In one, a truck needs to go into a
weighting station and each axle is weighted by conventional means. The
other is newer and a somewhat experimental method where a thin pad is placed
on the highway and axles are weighted as trucks pass over it. Former weight
are called static weights (sw) while later are called weights in
motion (wim).
