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
).
