The main objects of this invention are:
First, to provide a sanding apparatus for road
vehicles such as trucks which is effective in posi
tioning the sanding material relative to the trac
tion wheels and so that the likelihood of its get
ting into bearing parts or being blown away as it
is discharged is minimized.
