Which of the following is a precaution that can help prevent drowsy driving?

Setting a schedule with frequent driving limits is a crucial precaution to help prevent drowsy driving. This practice encourages drivers to take regular breaks during long trips, allowing them to rest and re-energize. It is critical because prolonged driving can lead to fatigue, significantly increasing the risk of drowsiness. By incorporating scheduled breaks, drivers give themselves the opportunity to stretch, hydrate, and relax, thereby maintaining a higher level of alertness while behind the wheel.

Establishing these limits can also help in planning trips more effectively, ensuring that driving distances are manageable and that rest areas are considered. This proactive approach is especially important for long-distance journeys where fatigue can accumulate without proper management.
