Frequent lane changes without signaling is an indication of a distracted driver because it shows a lack of attention to the driving environment and proper vehicle operation. A driver who is focused and attentive generally stays in their lane and uses signals to communicate their intentions to other road users. When drivers are distracted, they may make abrupt or random lane changes without alerting others, which can create hazards on the road. In contrast, maintaining a consistent speed suggests that a driver is in control of their vehicle and is paying attention to their surroundings. Using turn signals appropriately indicates that a driver is effectively communicating their intentions, showing awareness of other vehicles and traffic laws. Similarly, focusing on traffic signals demonstrates that the driver is attentive to their environment and obeying traffic rules. These behaviors generally reflect awareness and a responsible approach to driving.
