Beware I-40 in the vicinity of Hickory, NC. This is not so much a trap as it is a very blatant revenue enhancement zone. I drive I-40 across the whole state end to end each week and there is nowhere else on the entire length of the I-40 interstate in North Carolina where I see blue lights *every single time*. This is not a particularly dangerous stretch of road, but the speed limit drops from 70 to 65 and they take advantage of the fact that a large majority of drivers are moving at 75-80mph (not unreasonable for this road on a typical dry day) when they enter the enforcement zone.
