Planning a long drive? This calculator recommends how many rest breaks to plan for based on total driving time.
Recommended Stops = floor(Total Driving Hours / Rest Stop Interval)
Example
10 hours of total driving, resting every 2 hours:
Recommended Stops = floor(10/2) = 5 recommended rest stops
The 2-Hour Reference Interval
Safety guidance commonly recommends a rest break at least every 2 hours of continuous driving to combat fatigue and maintain alertness behind the wheel - drowsy driving is a well-documented contributing factor in a meaningful share of road accidents.
Shorten This Interval When Conditions Warrant
This interval should be shortened further for overnight driving, when driving through unfamiliar or monotonous terrain, or whenever drowsiness is noticed - the 2-hour guideline is a maximum reference interval, not a rule that overrides your body's actual fatigue signals.
