What can fatigue cause you to do while driving?

Fatigue significantly impacts your concentration and reaction time, which can lead to missing important signs and signals on the road. When a driver is tired, their ability to process visual information is impaired, making it difficult to notice crucial indicators such as stop signs, traffic signals, and other important road markings. This distraction can increase the risk of accidents since the driver may not respond appropriately to changing traffic conditions or instructions.

In contrast, maintaining your usual speed can still occur even when tired; however, it doesn't reflect an accurate understanding of how fatigue affects overall driving capabilities. The other options suggest behaviors that may not directly correlate with the impairment caused by fatigue, which primarily manifests through decreased alertness and awareness rather than speeding or maintaining speed.
