As has been shown in this thread, depending on the state, non compliance to MUTCD can be exculpatory. In other states proving non-compliance may not be exculpatory but it certainly could be persuasive. Rarely will proving non-compliance be adverse. Therefore, it is often beneficial to advise the defendant to look into it.
At minimum, can we all agree that if the defendant had trouble with a traffic control device and if compliance with MUTCD could have prevented such troubles, advising the defendant to look in to said non-compliance and use it to persuade their defense may be beneficial and should not instantly be discredited?
