Difficulty: EasyWork Zone Safety and Construction Hazards

You are driving on a multi-lane highway and enter a designated work zone where a temporary sign posts a reduced speed limit of 45 mph. Even though no construction workers are currently visible near the open lanes, what is the correct rule regarding your vehicle's speed?

  1. Obey the posted temporary 45 mph speed limit at all times while within the work zone.Answer
  2. B
    Resume the standard highway speed limit since workers are not actively working near the roadway.
  3. C
    Increase speed slightly to clear the work zone area as quickly as possible.
  4. D
    Come to a complete stop at the entrance of the work zone and yield to oncoming maintenance vehicles before continuing.

Answer

Drivers must obey the posted temporary speed limit within a designated work zone at all times, regardless of whether construction workers are visible.
Temporary posted speed limits in active construction zones are legally enforceable regulatory limits. Drivers must adhere to the posted reduced speed continuously through the designated zone, regardless of worker visibility, because road conditions and lane geometry remain hazardous.

Step-by-Step Solution

1
Identify the regulatory nature of work zone speed signs
Recognize that black-on-white or temporary regulatory speed signs set a legal maximum speed.
Work zones often present hidden hazards such as uneven pavement, shifted lanes, or narrow shoulders that require reduced speeds even when active crews are absent.
2
Determine the proper driving behavior
Maintain travel speed at or below the posted 45 mph limit until passing the end of the work zone.
State traffic laws enforce posted work zone speed limits continuously while the signs are displayed.
