The journey uses well-maintained highways in Austria, Slovenia, and Croatia, but Bosnia's roads (M17) are narrower and less illuminated.

• Essential gear: valid driver's license, registration, insurance (green card for Bosnia), headlamp converters for UK vehicles, and a warning triangle.
• Speed limits: 130 km/h on highways (Austria/Slovenia/Croatia), 90 km/h on rural roads, 80 km/h in built-up areas. Bosnia has 100 km/h on motorways.
• Border crossing: from Croatia to Bosnia at Metković or Imotski, average wait 20 minutes; have passports ready.

Road quality is excellent on highways, but the M17 from Split to Mostar is narrow with sharp curves and insufficient lighting at night. Drive during daylight. In Bosnia, watch for livestock on rural roads. For families, stop at Otočec Castle (Slovenia) for a picnic, or the interactive Museum of Illusions in Zadar.
