Answer: C — Motorists

The correct answer identifies motorists as the primary cause of over 50% of fatal injuries to road workers. This statistic highlights the significant risk that roadway construction and maintenance work poses to employees due to the presence of vehicles operating in close proximity. Motorists often may not be paying adequate attention to road closures, signage, and the presence of workers, which can lead to accidents. This danger is exacerbated in situations where drivers may be distracted, speeding, or failing to adhere to traffic signals and signs that indicate the presence of roadwork. Understanding this context is crucial for both motorists and road workers. For drivers, it emphasizes the need for vigilance and caution in work zones, recognizing that these areas often have unique hazards. For road workers, it underscores the importance of using proper safety measures and equipment to protect themselves while working in such environments. This information is vital for fostering a culture of safety on the road, thereby reducing the likelihood of accidents that can result in severe injuries or fatalities.
