Which scenario is an indicator that a driver should pull over and rest?

The scenario where a driver starts to daydream is a clear indicator that they should pull over and rest. Daydreaming while driving can lead to a significant reduction in attention and awareness of the road and surroundings. This mental detachment increases the risk of an accident, as the driver may not react appropriately to changes in traffic or hazards.

Recognizing signs of drowsiness or distraction, such as daydreaming, is crucial for maintaining safe driving practices. It signals that the driver is not fully engaged and may not be able to make quick decisions, which can jeopardize their safety and that of others on the road. Taking a break to rest or recuperate can help restore focus and alertness necessary for safe driving.
