Difficulty: EasySpeed Limits and Speed Regulation

In a designated highway work zone, posted reduced speed limits are legally enforceable only when construction workers are physically present on the roadway.

Answer: Answer

Answer

False. Posted reduced speed limits in highway work zones are legally enforceable at all times (or during posted times), regardless of whether construction workers are physically present.
The correct answer is False because posted work zone speed limits are statutory regulatory limits. They remain legally binding at all times unless specific sign sub-plates state otherwise, because dangerous road conditions and altered lane layouts remain present even when workers are off-duty.

Step-by-Step Solution

1
Identify the legal authority of posted regulatory speed limit signs in work zones.
Posted speed limit signs establish mandatory legal maximum speeds upon entering the designated zone.
Regulatory signs apply standard legal speed enforcement unless auxiliary signs explicitly restrict enforcement hours.
2
Evaluate whether physical worker presence is required for enforcement.
Worker presence is not required for the speed limit to be legally binding.
Work zones present continuous structural hazards—such as reduced lane widths, concrete barriers, rough pavement, and unexpected lane shifts—that require reduced speeds even when no workers are active.
