Are the expressways to Makkah fully serviced?
Yes. The main roads, such as Saudi Highway 40 (international route 80M from the Gulf through Riyadh to Taif and Makkah) and the Hijrah expressway, have full-service model stations open around the clock. Still, take care when driving at night.
Does the guide work on the road without internet?
Yes. Once you open your country page a single time, the browser saves all stations, the fuel calculator and the checklist so they work offline.
