Many of the problems associated with enforcing oversize and overweight limits derive from the confusing variety of requirements--for applications, fees, issuance, signs, flags, escorts, actual limits, fines--from state to state and within states.

The report strongly recommends that uniform standards for interstate overlimit travel be sought. Enforcement efforts and permit procedures also need to be coordinated.  The report for this topic can be purchased at https://www.trb.org/news/blurb_detail.asp?id=3488
