Road quality is excellent on highways, but sections in Slovenia (A2) have winding stretches. In Croatia, the A8 has straight sections with good lighting. Night driving is safe, but watch for wildlife in the Karst area. Toll booths in Croatia require slow approach.

Fuel stations are abundant along the A1 and A2 highways, with major brands like Shell, Aral, and OMV. In Slovenia, Petrol stations are common. Expect fuel costs around €1.50-1.70 per liter for gasoline. The route's topography includes steep climbs in the Alps, which can reduce fuel efficiency by 10-20%. Use cruise control on flats to save fuel.

• Estimated fuel cost: ~€80-100 for a compact car
• Fuel station frequency: every 30-40 km on highways
• Topography: Alps (climbs), Karst (plateau), coast (descending)
• Tip: Fill up in Austria (cheaper than Slovenia/Croatia)

Toll roads require vignettes: Austria (€9.90 for 10 days), Slovenia (€30 for 7 days), Croatia (toll booths, €15-20). Electronic vignettes are available online. Keep cash for Croatian tolls; not all accept cards.

• Slovenia vignette: purchased at border or online
• Croatia: pay at toll booths (Kuna or Euro)

Rest areas are well-maintained. The A1 has service stations every 50 km with restaurants and bathrooms. In Slovenia, the A2 has modern stops like Kompolje. In Croatia, the A8 has fewer stops; plan to refuel before entering.
