Final answer:
D. All of the above.
Signs of a distracted driver include moving at a different speed than traffic, unpredictable speed changes, and tailgating. These behaviors demonstrate a lack of attention to driving, posing risks to everyone on the road.
Step-by-step explanation:
Signs that another driver is distracted can involve various behaviors that indicate a lack of attention to the driving task. These behaviors include:
- Moving at a pace different from the flow of traffic, such as going faster or slower than other vehicles.
- Making unpredictable speed changes without any apparent reason.
- Tailgating, which is following another vehicle too closely.
All these behaviors can be indicators of distraction. Distracted driving is a safety hazard and can lead to accidents because it reduces the driver's ability to react to road conditions and the actions of other drivers.
