How should a driver respond to road signs indicating construction ahead?

When drivers encounter road signs indicating construction ahead, the appropriate response is to slow down and follow posted detours or instructions. Construction zones often have reduced speed limits, which are in place to ensure the safety of both workers and drivers. By slowing down, drivers allow themselves more time to react to any sudden changes, such as workers entering or exiting the roadway or unexpected obstacles.

Following posted detours or instructions is crucial, as these signs provide information on alternate routes or specific guidelines that help maintain an orderly flow of traffic while construction work is ongoing. This helps in minimizing congestion and ensures that the construction work can proceed safely and efficiently.

The other choices do not prioritize safety and could lead to dangerous situations. For example, ignoring the signs might result in entering a hazardous area without being aware of the potential dangers. Speeding up could increase the risk of accidents, especially if workers or equipment are close to the roadway. Abruptly changing lanes can create confusion and may lead to collisions with other vehicles. Hence, cautious and attentive driving in response to construction signs is essential.
