Verify service availability
Hours and seasonal operation can change.
Tell someone the route
Especially where long sections have limited traffic or coverage.
Carry more margin
Fuel/charging, warm clothing and trip timing should be conservative.
Do not rely on one app
Offline maps plus official road information are useful when coverage is weak.
General travel-planning information only. Drivers must follow licence restrictions, traffic laws and current road-authority directions. Do not continue driving when fatigued or when weather, closures or road conditions make the trip unsafe.
