There may be someting else to consider ... at a "main truck entrance" the 
speed of the truck is, what, 10,20 or 30 mph and the detector can be mounted 
fairly close to the trucks path.  On a highway trucks are going, what, 55 to 
65 mph and the distance from the detector to the truck is likely to be 
considerably further.
