20 famous European road trips, each coloured by whether a car towing a caravan may drive it: 10 the whole road, 7 with a bypass, 3 not at all (Stelvio, the Amalfi coast road, the Lake District’s Hardknott/Wrynose loop).

A few things that surprised me while reading the rules:

• Amalfi coast road (SS163): campers and caravans are banned 06:30–24:00, while motorbikes are exempt from the odd/even number-plate days cars get in summer.
• Grossglockner: a motorcycle’s day ticket is €36.50 against €46.50 for a car — and a car with a caravan pays the car rate.
• Geiranger–Hellesylt ferry: about €76 for a car with its driver, €187 for a car + caravan (10–14 m), €61 for a motorbike.

Rules read on 5 Nov from the road authorities and operators (where only a secondary source says it, the page says so). Each road is priced for car, car + caravan, motorhome and motorcycle: https://copilot.travel/maps/famous-road-trips Corrections welcome.
