Which of the following conditions can affect a vehicle's handling?

Environmental conditions are a significant factor affecting a vehicle's handling. These conditions can include various elements such as weather (rain, snow, ice, or fog), road surface conditions (paved, gravel, or dirt), and even the type of terrain (hilly, flat, or urban). For instance, wet or icy roads can lead to decreased traction, which impairs a vehicle's ability to stop or turn effectively, thereby impacting overall handling and safety.

In contrast, engine size, while it can influence acceleration and performance, does not directly affect how a vehicle responds to road conditions. The color of the vehicle has no bearing on its handling characteristics or performance. Similarly, the type of fuel used can affect engine performance and efficiency but does not directly impact how well a vehicle can handle different driving conditions.
