Residential neighborhoods will often have a sign banning trucks (heavy goods 
vehicles) unless they are making a delivery in that neighborhood. They don't 
want heavy vehicles using the road as a through route.

Also, a road may be unsuitable for large vehicles because of limited overhead 
clearances, small-radius curves or intersections, or because the pavement 
wasn't constructed strongly enough for a vehicle that heavy.  Dump trucks, in 
particular, will break up the surface of a roadway because the weight on each 
axle is so great.
