What is the health and safety concern associated with inadequate highway design?

Inadequate highway design is primarily associated with a higher risk of accidents due to improper road conditions. When highways are not designed to accommodate traffic flows, vehicle types, and changing road conditions, it can lead to a number of hazardous situations. For instance, poor sightlines, improper lane widths, insufficient shoulder space, and inadequate signage can all contribute to driver confusion and increased likelihood of collisions.

Additionally, features such as sharp turns, steep grades, and lack of appropriate drainage can exacerbate these risks. A well-designed highway takes into account these factors to minimize the potential for accidents and enhance overall road safety for all users. By focusing on proper engineering and design standards, highway safety can be significantly improved, which is why this option accurately highlights the main health and safety concern associated with inadequate highway design.
