How is the position evaluated if a vehicle straddles the single center stripe, except when passing?

When evaluating the position of a vehicle that straddles the single center stripe, the assessment focuses on the control and positioning of the vehicle within the lane. Straddling the center stripe typically indicates a lack of adherence to lane discipline, which may pose risks to the driver and other road users. This behavior can suggest that the driver is not fully in control of the vehicle or is not maintaining a safe and appropriate lane position.

The grading of “Bad” reflects the significant concerns associated with this action. A vehicle that is straddling the center line could potentially interfere with oncoming traffic when there is no safe passing opportunity, leading to dangerous situations. In practice, maintaining proper lane positioning is crucial for safety and requires a good understanding of spatial awareness on the road.

On the other hand, designations like "Good," "Fair," and "Excellent" would imply a satisfactory or commendable lane position, which is not evident when straddling the center stripe. Therefore, "Bad" accurately represents the level of risk and control issues resulting from this maneuver.
