Expressways are designed to assist drivers in early identification of roadway:
a) Hazards and conditions
b) Speed limits
c) Traffic flow
d) Traffic volume
The correct answer and explanation is:
The correct answer is a) Hazards and conditions.
Expressways are high-speed roads designed to provide a smooth, continuous flow of traffic with minimal interruptions. They are typically constructed with limited access points and few intersections, which allows drivers to travel at faster speeds and with fewer obstacles. However, this design also means that drivers need to be highly aware of potential hazards and changing road conditions that can affect their safety.
One of the primary purposes of expressways is to help drivers identify hazards and conditions early. This includes things like sudden changes in road conditions, construction zones, wildlife crossings, and adverse weather conditions. Road signs, lighting, lane markings, and other visual cues along the expressway are designed to give drivers enough time to adjust their speed and behavior to reduce the risk of accidents.
In addition to warning drivers about hazards, expressways are also equipped with features like shoulders and emergency lanes, which provide drivers with more space to maneuver in case of a breakdown or emergency. Signage on expressways often includes information on upcoming curves, ramps, and exits, which further assists drivers in anticipating potential hazards.
By identifying hazards and conditions early, expressways help maintain a safer driving environment. Drivers can make informed decisions about speed adjustments, lane changes, or stopping. This is crucial, especially when traveling at high speeds, where a delay in recognizing potential dangers can have severe consequences. In this way, expressways contribute to safer and more efficient traffic flow by providing the necessary tools for drivers to respond to road hazards in a timely manner.
