How frequently should breaks be taken on long road trips to prevent fatigue?

Taking breaks every two hours or every 100 miles is a recommended practice during long road trips to prevent fatigue. This approach allows drivers to refresh themselves, stretch their legs, and take a moment away from the driving task, which ultimately helps reduce the risk of drowsiness and improves overall driving performance. Regular breaks contribute to better focus, alertness, and decision-making on the road.

In comparison to the other options, breaks every hour may not provide sufficient rest for some individuals, especially on longer trips. Every three hours could be too infrequent for maintaining alertness, increasing the likelihood of fatigue setting in. Waiting until one feels tired to take a break is not advisable, as fatigue can develop gradually and may impair judgment before the driver even realizes it. Thus, regularly scheduled breaks are essential for safe driving on long journeys.
