To my left is a small hut in which a gruff-looking road controller sits, peering out of a frosty window to check on the conduct of the passing vehicles. To the right is a sign that sets out the road rules for the journey ahead.
They're not your normal kind of traffic rules. On this particular road, it is forbidden to wear a seatbelt: you might have to make an unexpected and speedy exit from your car.
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.
