I use to guy a mobile fiberglass pole for that purpose. Was ecstatic
over the performance until I smashed some low service station lights..

The greatest height a car/truck can be on the highways is 13'6". Mount
the ant on a lightweight fiberglass pole with the tip of ant at this max
height?

USA here. Yes, I have gotten used to watching for low overhangs when
using the fiberglass pole. I have one I got off ebay, it is hollow and
about 1-1/8 od and telescopes. This is handy for having the vhf/uhf/shf
at any height one wishes ...

You are quite right though, 13'6" may only apply in USA. That height is
established by big trucks, they can't put overpasses lower than that or
the trucks can't get past--and everyone needs the privy paper, now don't
they? ;-)
