urgency on the part of the CHP to refer to a vehicle code to enforce the
height.

Depending on structural integrity, that would be self-enforcing,
wouldn't it?

From http://en.wikipedia.org/wiki/Interst...hway_standards

Vertical clearance. Minimum vertical clearance under overhead
structures (including over the paved shoulders) of 16 ft (4.9 m) in
rural areas and 14 ft (4.3 m) in urban areas, with allowance for extra
layers of pavement. Through urban areas at least one routing should
have 16 ft (4.9 m) clearances. Sign supports and pedestrian overpasses
must be at least 17 ft (5.1 m) above the road, except on urban routes
with lesser clearance, where they should be at least 1 ft (0.3 m)
higher than other objects. Vertical clearance on through truss bridges
is to be at least 17 ft (5.1 m).
