What does this tool do?
Long drives need planned breaks, and each stop adds to the arrival time. This calculator spaces stops evenly through the driving time and shows how much the breaks add to the journey.
The Formula
Stops = ⌈Driving time ÷ Stop interval⌉ − 1; Total time = Driving time + Stops × Stop lengthFrequently Asked Questions
How often should I stop on a long drive?
A common guideline is a break every two hours, and more often at night or in poor weather. Stop earlier if you feel tired; fatigue is a major crash risk.
Why does the planner show one fewer stop than expected?
The final stop interval ends at the destination, so the last break is not counted. For a four-hour drive with a two-hour interval, one stop is included.
