While the posted speeds are always lower than the actual traffic speeds I have never seen any police pull over a vehicle on a major toll or major country/state road (***only on posted low speed zones, school zones, and on secondary/municipal roads are the police merciless). General rule on the autobahns and toll roads fit in with traffic speeds (which will be faster than your used to); off the autobahns and toll roads drive slower than you would normally do in North America.
Toll Roads and Route Planning
One of the 'bad' things about driving in Europe is their extensive toll road system.
It will be difficult but not impossible to avoid toll roads in Europe—especially in Italy. Make sure you review the following links carefully, do some route planning, and carry enough Euros coins. We can assure you that there are very good secondary roads in most European countries (Italy the only exception we found on our last trip) so don't be afraid to avoid the toll roads if you can; they will not significantly increase travel time or distances.
Nothing But the Facts
Whether you're in the fast lane on the autobahn or in a motorhome pursuing whims down country lanes, Europe offers every driving experience. Thanks to relatively short distances, motorists can find themselves driving across three countries in a single day, or from the seashore to the high sierra in an afternoon.
Touring Europe by Motorhome
Because Europeans are as RV-happy as Americans, Europe is well-organized for motorhome travel. It’s a great travel option for U.S. visitors
Motorhomes allow you to go just about anywhere with all the comforts of home. And of course, motorhome vacations are an excellent way to meet Europeans with similar interests.
Europe welcomes motorhomes to more than 8,000 campgrounds. Excellent facilities are found within many major cities (and street parking is OK for up to 24 hours in most). Campgrounds often have private showers, laundromats and supermarkets. Tourist offices will have detailed information on what’s available where.
Renting a Car in Europe Renting a car in Europe is no different than in North Amercia. You will need a valid driver's license (International driver's license in not normally required), be 25 or older, and have a major credit card.
