When driving through construction zones, what is the best practice regarding speed?

The best practice regarding speed in construction zones is to follow the posted construction zone speed limits. These limits are specifically set to enhance safety for both drivers and construction workers. Construction environments often involve unpredictable situations, including lane shifts, moving equipment, and personnel working close to traffic.

By adhering to the posted speed limits, drivers reduce the risk of accidents and increase their reaction time to unexpected changes in traffic patterns or hazards. These limits are usually lower than regular speed limits to account for the unique dangers present in these areas. Signage indicating reduced speed in construction zones is installed to alert drivers to the need for greater caution, reflecting the heightened risks associated with these environments.

The other options do not prioritize safety effectively. Speeding up can lead to dangerous situations, while maintaining normal driving speed neglects the specific adjustments required for the construction context. Simply slowing down only when seeing workers does not account for potential hazards that could arise before a driver is close enough to see them. Thus, following the posted construction zone speed limits is the safest and most responsible approach in these areas.
