The longest ice road in Europe (16 miles) stretches across the frozen surface of the Baltic Sea and connects the Estonian coastline to the island of Hiiumaa. There are strict traffic rules for this particular road.
It is strictly forbidden to wear a seatbelt because you may have to make a fast and unexpected exit from your car. If your vehicle does crack the ice, it should sink slowly enough for you to still get out. You are not allowed to drive there after sunset. It is illegal to travel between 16-25 mph. That could crack the road surface as your tyres will create dangerous vibrations at those speeds.
Traveling on ice is part of the culture of the Estonian islands. In the 13th century the islands were conquered by Teutonic knights who thundered across the ice on horseback. Villages have been built by pulling supplies across the ice from the mainland. Nowadays the locals look forward to the ice-driving season. It is cheaper than to pay for fare aboard a vehicle ferry and much more convenient.
Wolves, moose and bears also enjoy the ice road as it gives them passage to and from the island in search of food.
