What is one reason why expressways are safer than other roads?

• A. They have more traffic signals
• B. They have higher speed limits
• C. There is a median dividing lanes of traffic
• D. They allow for more lane changes

Answer: (C)

Expressways are designed with safety as a priority, and one of the key features contributing to their enhanced safety is the presence of a median that divides lanes of traffic. This median acts as a physical barrier that minimizes the risk of head-on collisions by preventing vehicles traveling in opposite directions from crossing into each other’s paths. This separation of traffic flows helps to reduce the likelihood of accidents that can occur on roads without such dividers. Additionally, expressways are often constructed with multiple lanes in each direction and controlled access points, which further enhance safety by reducing potential conflict points. In contrast, roads with more traffic signals or those allowing for frequent lane changes can create situations that lead to increased driver distraction and potential for collisions. Therefore, the design features of expressways, including the median, play a significant role in improving overall traffic safety.
