Final answer:
Signs that a driver may be confused or impaired include erratic driving, slowing or stopping suddenly without warning, and being distracted by looking at a paper map. All of these behaviors can be hazardous and indicate the driver is not fully focused on driving.
Step-by-step explanation:
Which of the following are signs a driver may be confused or impaired? The correct answer is this: such signs include erratic driving, slowing or stopping suddenly and without warning, and instances where a driver is looking at a paper map while driving. All of these behaviors could indicate that a driver is not paying full attention to the road or is having difficulty navigating, which can be signs of confusion or impairment.
Erratic driving can include various unpredictable maneuvers such as swerving, changing speeds rapidly, and ignoring traffic rules. Slowing or stopping suddenly can be dangerous to other drivers and suggest that the driver is unsure of their destination or reacting to something internal rather than external road conditions. Looking at a paper map might indicate that the driver is distracted or lost. These behaviors are a concern for the safety of the driver and others on the road. Therefore, the comprehensive answer to the question is D. All of the above.
