Driver Sleep Planner
Plan when to sleep and wake up before work.
Clock format
24-hour military time
Enter when work begins and how much sleep you want. Your planned sleep and wake-up times appear below.
About 9.0 hours awake when work starts and 7.0 hours of recent sleep including the planned nap.
Alertness may fall while you are working. Plan a legal break or short nap before the risk period and reassess how you feel.
Your planned work time overlaps 2:00–6:00 AM (strongest dip) and 12:00–2:00 AM.
If fatigue builds, a brief 15–30 minute nap in a safe location may improve alertness. Allow time to fully wake up.
This planner estimates rest opportunities. It does not determine whether you are safe or legally permitted to drive. If you feel drowsy, stop in a safe location.
Reference only. Always follow current regulations, carrier policy, permits, posted signs, and enforcement instructions.
