Fine for stop to sleep. Truck parking was full at 22:45 on a Saturday night. Luckily the height restriction was open on the main car park. Right next to road and many trucks around, so it's noisy. Fuel, shop, cafe, McDonald's, toilets. The next morning we stopped at the next place a few kms east, Shell Autohof Eisenach Süd. That's more off the road, so would have been a better place to sleep.
