• Rest areas are available approximately every 20 km on the A71, with many providing fuel, restrooms, and picnic tables.
• Fuel stations are dense on this route; major brands (Total, Shell, Esso) appear near junctions. However, between Clermont-Ferrand and Vierzon, stations become sparse for about 60 km—fill up ahead.
