A 16 miles (25km) stretch of road connecting the Estonian coastline to the island of Hiiumaa is probably one of the world’s oddest when it comes to traffic rules.
Because the road is made of ice and stretches across the frozen surface of the Baltic Sea, drivers are forbidden from wearing their seatbelts or driving between 15.5mph (25km/h) and 25mph (40km/h).
Ice road between Hiiumaa and the mainland.
You can’t drive here after sunset, or with a vehicle over 2.5 tonnes. And it is strictly illegal to travel at between 25 and 40km/h (16-25mph). At those speeds, your car tyres will create dangerous vibrations that could crack the surface of the road, sending you and your vehicle to a watery grave.
