Roads are generally safe, but watch for livestock in rural Spain and sudden fog in the Pyrenees. Speed cameras are common; respect limits (120 km/h in Spain, 130 km/h in France). Family suitability is high: there are many playgrounds at motorway rest areas, and attractions like Futuroscope (Poitiers) or Parc Astérix (near Paris) require detours. Pet-friendly hotels are abundant, with many French chains accepting dogs. Rest zones are every 30 km on major highways; plan for a 15-min break every 2 hours. Fatigue management: avoid driving between 2-5 PM; use coffee stops at service stations.
