chapter 6 — sharing the road If you are in the lane nearest to the stopped vehicle displaying  flashing lights, you must also change lanes if safe to do so. Slow down and leave space when passing vehicles with flashing  lights on the sides of roads. Change lanes to provide safe space  margins if it is safe to do so. Road crews work throughout  the year to maintain and  improve our roads.  Despite construction zone  signs and traffic control  persons, crashes still occur  in construction zones, mainly  because some drivers don’t  pay attention. Scan ahead  — look for construction zones ahead and be  prepared to obey traffic control devices within the zone.  Pay attention at night  — road construction doesn’t just occur  in the daytime. With the high daytime traffic volumes, more  and more road construction takes place at night. You need to  pay extra attention and drive extra slowly through construction  zones at night.  Look around  — just because you don’t immediately see traffic  control persons, construction or workers in a construction zone  doesn’t mean they are not there. Be alert for traffic control  persons, construction workers and equipment.  Know the rules  — you must obey the directions of traffic  control persons and road construction signs from the start to  the end of the construction zone. Construction zone speed  limits apply 24 hours a day when posted. Think ahead  — construction zones often require lane closures,  so you may need to change lanes. Merge to avoid a lane  closure as soon as you can. This will help maintain traffic flow.  Plan ahead  — expect delays, and plan for them by leaving  early to reach your destination on time.
