Question

you are driving on a highway and are approaching a construction zone; select a letter to choose your answer. a you should drive 20 miles per hour below the standard speed limit for that highway. b you must slow to 30 miles per hour. c the proper speed for the construction zone will be posted on speed limit signs and warning signs in the construction zone.

Explanation:

When approaching a construction zone on a highway, the speed limit is not a fixed value like 20 miles per hour below the standard or 30 miles per hour in general. Instead, the proper speed is determined by the posted speed limit signs and warning signs in the construction zone. These signs are set based on the specific conditions (such as the type of construction work, presence of workers, equipment, etc.) in that particular zone.

Answer:

C. The proper speed for the construction zone will be posted on speed limit signs and warning signs in the construction zone.
