In which situation is increased warning signage required on highways?

• A. Poor lighting conditions
• B. High traffic volume
• C. Complex road geometry
• D. Heavy vehicle traffic

Answer: (C)

Increased warning signage is particularly crucial in situations involving complex road geometry. This includes areas with sharp turns, intersections with irregular layouts, or sudden changes in road configuration. Complex road designs can pose unexpected challenges for drivers, who may not be familiar with the road. By implementing additional warning signage, road authorities ensure that drivers are adequately alerted to potential hazards, allowing them to navigate the area safely and effectively. While poor lighting conditions, high traffic volume, and heavy vehicle traffic all have their own implications for road safety, they do not inherently necessitate increased warning signage related specifically to the road's layout and navigation. In contrast, complex geometry directly impacts how drivers perceive and react to the road, which is why enhanced warning signage is necessary in these contexts. Proper signage can significantly reduce the risk of accidents that may occur due to driver confusion or miscalculations in these challenging driving environments.
