Calculation method

A planning estimate, not a traffic forecast

The planner converts miles and mph to kilometres and km/h, then divides distance by average speed. It inserts a break before the destination whenever another full break interval would be reached.

The result does not know traffic, roadworks, weather, borders, charging, fuel stops or time spent finding parking. Use a realistic average speed and add extra margin for your route.

Pure driving time

Distance ÷ average speed gives the time spent moving. Unit conversions happen locally before this calculation.

Rest break count

Breaks equal the planned intervals reached before arrival. A break is not added at the destination itself.

Total estimate

Total time = pure driving time + rest breaks × minutes per break. The optional arrival time adds this duration to departure.

Fatigue and break guidance

This planner helps you model a schedule; it does not set a legal driving limit. Use the official guidance below and check the rules for your vehicle and route.

  • NHTSA: Drowsy Driving The US National Highway Traffic Safety Administration advises drivers to stop in a safe, designated place when sleepy; its guidance includes a short nap as a temporary measure.
  • UK Highway Code Rule 91 The UK Highway Code says tired driving raises collision risk and recommends planning at least a 15-minute break after every two hours of driving.

If you feel sleepy, stop in a safe place and do not rely on a calculated arrival time. Commercial-driver hours, local laws and employer rules may require different breaks.

Driving time and break questions

How does the planner count breaks?

It counts planned breaks that occur before arrival. For example, a 6-hour driving estimate with a break every 2 hours produces two breaks, at the 2-hour and 4-hour points. It does not add a break at the destination.

Does average speed include traffic?

Only if you include your expected traffic-adjusted average. The planner has no live traffic or route data, so it cannot predict congestion, stops, roadworks, ferries or border delays.

Is a 15-minute break every two hours a universal rule?

No. It is a recommendation in UK Highway Code Rule 91, not a universal legal rule for every driver or country. Check the current authority guidance for your vehicle, route and jurisdiction.

What should I do if I become sleepy?

Stop as soon as it is safe, use a designated rest area when possible, and rest. NHTSA warns that caffeine alone is not enough when you are seriously sleep-deprived; do not continue just to meet a calculated arrival time.
