How frequently should drivers assess their duty status during a trip?

Drivers should assess their duty status before a change in driving conditions to ensure they are aware of their current physical and mental state, as well as adjusting to new driving environments. Changes in driving conditions can include entering a different type of road, inclement weather, or changes in load or cargo. Assessing duty status in such situations allows drivers to make informed decisions about their readiness to drive safely.

Monitoring duty status is crucial to maintain safety and prevent fatigue, which can significantly impair driving performance. Being mindful of one’s condition in response to environmental changes not only ensures compliance with regulations but also promotes better safety outcomes and reduces the risk of accidents on the road.
