Work Zone Reduced Speed Limit
Regardless of the posted speed limit, it may be necessary to reduce your speed to keep yourself and others safe. Signs will show when a reduced speed limit is in effect. (p12) For safety reasons, normal speed limits may be reduced in work/construction zones. Any reduced speed limits will be clearly marked. Failure to follow the speed limit in a work/construction zone can result in double fines. (p12) Obey construction signs, including work zone speed limit signs, and flagger instructions. (p18)
