The main highways are well-maintained, with good signage and frequent rest areas. Toll gates are present on the A4 and A31; expect to pay with credit card or cash. Rest areas typically have clean restrooms, vending machines, and picnic tables. Fuel stations are plentiful, with a concentration every 30-40 km.
