Which of the following are signs a driver may be confused or impaired?

Answer: B — Erratic driving

The signs that indicate a driver may be confused or impaired include erratic driving. This behavior suggests a lack of control or awareness on the part of the driver, reflecting their inability to maintain a consistent or safe driving pattern. Erratic driving can manifest as sudden turns, swerving, unpredictable acceleration, or abrupt stops. Such actions are critical warning signs of impaired judgment or confusion and highlight the importance of being aware of other drivers' behaviors on the road to ensure safety for everyone. In contrast, maintaining a steady speed and using turn signals properly indicate a driver is in control and aware of their surroundings, while frequent lane changes can be a normal part of driving, especially in traffic, unless they are executed in a reckless or dangerous manner. These factors do not inherently suggest confusion or impairment.
