Final answer:
Drivers should be more careful in construction zones on freeways due to reduced speed limits, changing traffic patterns, presence of construction workers and machinery, and narrower lanes.
Step-by-step explanation:
Drivers should be more careful on freeways with construction zones for several reasons. First, construction zones often have reduced speed limits and changing traffic patterns, making it more challenging to navigate safely. Second, there may be construction workers and machinery present, increasing the risk of accidents. Additionally, construction zones often have narrower lanes, which can make it difficult to maneuver and require more attention from drivers.
