If a driver straddles a single center stripe except when passing, how is their position rated?

When a driver straddles a single center stripe except when passing, their position is rated as "Bad" because this behavior indicates a lack of proper control of the vehicle within the lane. Straddling the center stripe suggests that the driver is not maintaining a safe and appropriate pathway on the road, which could lead to dangerous situations such as encroaching into oncoming traffic. In general, proper lane positioning is crucial for safe driving, and drivers should stay within their designated lane boundaries unless they are executing a safe passing maneuver. This action of straddling not only poses a risk to the driver but also to other road users, which is why it receives a negative rating.
