Ask a Trooper: Know the difference between sign colors

Question: Are orange signs supposed to be advisory or warning signs? Can you get a ticket for going the speed of the white sign when there is also some orange signs posted? I’ve seen some construction zones with white and orange signs posted 55mph and then some orange signs with 35mph speed signs. What is the legal speed limit?

Answer: The white speed limit signs are the official regulatory sign. The orange signs serve as a warning; even though they are not regulatory they are intended to provide clear instructions to help you drive safely.

So if the posted speed limit is 55 mph, and you see an orange sign indicating 35 mph, I would recommend slowing to the indicated speed. Minnesota signs, signals, and pavement markings conform to the national standards.
