Sec. 393.20  Clearance lamps to indicate extreme width and height.

    Clearance lamps shall be mounted so as to indicate the extreme width 
of the motor vehicle (not including mirrors) and as near the top thereof 
as practicable: Provided, That when rear identification lamps are 
mounted at the extreme height of the vehicle, rear clearance lamps may 
be mounted at optional height: And provided further, That when mounting 
of front clearance lamps at the highest point of a trailer results in 
such lamps failing to mark the extreme width of the trailer, such lamps 
may be mounted at optional height but must indicate the extreme width of 
the trailer. Clearance lamps on truck tractors shall be so located as to 
indicate the extreme width of the truck tractor cab.
