Driver Sleep Planner
Plan rest around your shift and natural body-clock lows.
Clock format
24-hour military time
About 9.0 hours awake at shift start and 7.0 hours of recent sleep including the planned nap.
Alertness may fall during the shift. Plan a legal break or short nap before the risk period and reassess how you feel.
Your estimated shift 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.
