Road Trip Stops Calculator
Plan your road trip rest stops and fuel stops.
Enter distance, speed, and tank range to get a full stop schedule.
Road trip planning involves calculating your total drive time, how many fuel stops you need, and when to take rest breaks for safety and comfort.
The core formulas:
Total Drive Time = Total Distance / Average Speed
Number of Fuel Stops = Total Distance / Tank Range
Rest Stops Needed = Total Drive Time / Hours Between Breaks
Tank range calculation:
Your tank range tells you how far you can go on a full tank of fuel.
For imperial: Tank Range (miles) = Tank Size (gallons) × Fuel Efficiency (MPG)
For metric: Tank Range (km) = Tank Size (liters) × Fuel Efficiency (km/L)
It is best to stop for fuel at about 75% of your maximum range. This gives you a safety buffer and avoids the stress of searching for a gas station on fumes.
Rest stop guidelines:
Most driving safety organizations recommend taking a break every 2 hours or 100–120 miles (160–200 km). Fatigue is a major factor in road accidents, especially on long highway stretches.
Recommended rest stop schedule:
- Every 2 hours: 15-minute stretch and bathroom break
- Every 4 hours: 30-minute break with food or a short walk
- Every 8 hours: Consider stopping for the night
Speed and time estimates:
| Road Type | Imperial | Metric |
|---|---|---|
| Highway | 60–70 mph | 100–115 km/h |
| Rural roads | 45–55 mph | 70–90 km/h |
| Mixed driving | 50–60 mph | 80–100 km/h |
Practical planning tips:
- Add 15–20% extra time to your estimated drive time for traffic, construction, and stops
- Plan fuel stops near highway exits with multiple gas station options for better prices
- Download offline maps in case you lose cell signal in rural areas
- Pack snacks and water to reduce the number of long food stops
- Share driving duties if possible — switching every 2–3 hours reduces fatigue
- Avoid driving between 2:00 AM and 5:00 AM when drowsiness peaks
Common tank sizes:
- Compact car: 10–13 gallons (38–50 liters)
- Sedan: 13–16 gallons (50–60 liters)
- SUV: 16–22 gallons (60–83 liters)
- Truck: 22–36 gallons (83–136 liters)
