Making sudden or erratic speed changes can be a clear indication that a driver is distracted. When a driver is attentive and focused on the road, they generally maintain a consistent speed and are able to adjust their speed smoothly in response to changing road conditions, traffic patterns, and signals. Distracted driving often leads to an inability to react appropriately to the flow of traffic; this might manifest as sudden acceleration or deceleration, or erratic behavior in terms of speed. Such actions can be attributed to distractions, whether they stem from mobile devices, conversations, or other diversions that divert attention from driving responsibilities.

On the other hand, behaviors like consistently exceeding the speed limit, driving steadily within the speed limit, and maintaining a safe following distance, do not serve as clear indicators of distraction. Instead, maintaining a safe following distance and adhering to the speed limit suggest that a driver is likely paying attention to the driving task and managing their vehicle appropriately.
