Which feature is not typically designed to improve truck aerodynamics?

Wide, flat mirrors are not typically designed to improve truck aerodynamics. In contrast, features like slanted windshields, integrated roof fairings, and aero headlights are specifically engineered to minimize air resistance by streamlining the flow of air over the vehicle. These aerodynamic enhancements help reduce drag, improve fuel efficiency, and enhance overall vehicle performance.

Slanted windshields create a smoother transition for air as it moves around the front of the truck, effectively redirecting airflow to reduce turbulence. Integrated roof fairings are designed to bridge the gap between the truck cab and the trailer, further smoothing the airflow. Aero headlights often have streamlined shapes to decrease wind resistance. In contrast, wide, flat mirrors can create significant wind resistance, which is why they don’t contribute to improved aerodynamics.
