Duluth, MN (NNCNOW.com) --- In this week's "Ask a Trooper" article, Sgt. Curtis Mowers with the Minnesota State Patrol discusses the proper way of driving through construction zones. Question: Can you address the correct way to drive through a construction zone when posted “reduce speed – 45 MPH Fines double in construction zones”? What is the proper speed when no workers are present, such as evening and night time hours? Are the rules the same in all states? Answer: The posted speed limit is what you need to drive, whether or not there are workers present. You may need to drive slower or you might even have to stop if there is a flagman there directing traffic. You should always be watching ahead for hazards. When you start seeing signs, cones, barrels, barricades and other work zone indicators, start to slow down immediately. Remember to pay attention to the speed signs and to workers on sight. Always drive according to all of the existing conditions, but never more than the posted limit, especially in a work zone. When you see the signs asking you to reduce your speed ahead, then you’ll know that the speed limit may have been reduced in the work zone area. The posted speed limit (even in work zones) should be obeyed in every state. There really are no special rules that apply other than the signs you see.
