During the stopping sequence, what is an indication that a driver is likely impaired?

A driver striking the curb or another object during the stopping sequence is a strong indication of impairment. This behavior suggests a lack of control and awareness, which are common signs associated with alcohol or drug influence. Impaired drivers often have difficulty maintaining proper lane position and may misjudge distances, leading them to hit curbs or other objects.

In contrast, indicators like accurate directional signals, maintaining a constant speed, or stopping at green lights tend to demonstrate good driving behavior. While these actions are certainly positive, they do not necessarily provide evidence of impairment. The ability to signal turns correctly, keep a consistent speed, or adhere to traffic signals may suggest the driver is capable of handling the vehicle well, which stands in stark contrast to the erratic behavior of hitting curbs or objects that typically signifies impairment.
