Why is it crucial for drivers to obey posted speed limits in work zones?

Answer: C — Because of the presence of workers on-site.

Obeying posted speed limits in work zones is crucial primarily because of the presence of workers on-site. In these areas, construction activity often takes place very close to the roadway, which significantly increases the risk of accidents. Workers may be performing tasks that require their attention, and they may not be able to quickly react to approaching vehicles. By adhering to lower speed limits, drivers can enhance safety for both the workers and themselves, allowing for more reaction time and reducing the likelihood of serious injuries or fatalities. While factors such as fines or fuel consumption may influence driver behavior, the central concern in work zones is the protection of human life. Therefore, understanding and respecting the speed limits not only promotes individual safety but also contributes to the overall well-being of the construction crew working in precarious conditions.
