Trip Time Calculator
Pure driving time is never the whole trip. Add your break habit and get a realistic total time and arrival estimate.

Worked example
A 450 km drive averaging 90 km/h, with 10 minutes of breaks per hour of driving, leaving at 08:00:
- Driving time: 450 ÷ 90 = 5 hours
- Breaks: 5 hours × 10 minutes = 50 minutes
- Total: 5 h 50 min, so an 08:00 start arrives at about 13:50
How this calculator works
Average speed does the heavy lifting in this estimate, and it is the input people most often flatter. Highway cruising at 110 km/h with town ends, traffic, and a ferry or construction zone rarely averages above 85 to 95 km/h door to door in Canada.
Common questions
How often should I actually stop?
Transport Canada and provincial safety guidance generally suggest a break at least every two hours on long drives, and sooner if you feel drowsy. Ten minutes per hour in this calculator is a comfortable planning rhythm; fatigue is the real limit, not the schedule.
Why does my navigation app give a shorter time?
Navigation apps assume you drive the whole way without stopping and use current traffic plus posted speeds. They are estimating wheels-turning time. Add your breaks on top of their figure, which is exactly what this calculator does with its own average.
Estimates only. Results are provided for planning purposes and are based on the figures and assumptions shown on this page. Actual trip times vary with traffic, weather, construction, and road conditions. Never drive fatigued to meet an estimated arrival time.
