Meh, if we're going to get our panties in a bunch about something, let's try the slippery road surface sign... http://i.telegraph.co.uk/multimedia/archive/0269

Nothing wrong with a sign saying you’ll spin your car on a slippery road!

  >Nothing wrong with a sign saying you’ll spin your car on a slippery road! The point is - I believe - that in the given version (UK) the traces of the tires cross. The Italian (possibly normal EU) version is different: https://www.laleggepertutti.it/wp-content/uploads/2013/06/Resized-UT6AR-450x270.jpg https://www.laleggepertutti.it/wp-content/uploads/2013/06/Re... and tires trace are "normal". And this is the German version: https://upload.wikimedia.org/wikipedia/commons/thumb/b/b4/Zeichen_114_-_Schleuder-_oder_Rutschgefahr%2C_StVO_2013.svg/120px-Zeichen_114_-_Schleuder-_oder_Rutschgefahr%2C_StVO_2013.svg.png https://upload.wikimedia.org/wikipedia/commons/thumb/b/b4/Ze... where a "third trace" appears.

    They cross because the car on the sign has spun 180˚ rather than simply sliding. As the car spins the tracks from the left wheels cross over the tracks from the right. I admit that the German one is weird, but if the car has taken the corner at an angle and fast enough that it’s lifted a wheel you could see those tracks. (e.g. http://1.bp.blogspot.com/-JJVUFblJPIU/T0bmqmdpNFI/AAAAAAAAER0/eEWTF9IBCgw/s1600/Front+Wheel+Lift.JPG http://1.bp.blogspot.com/-JJVUFblJPIU/T0bmqmdpNFI/AAAAAAAAER... )

Which means that when UK roads are slippery, they are really slippery, or maybe continental drivers manage to get away without a 180° spin. However if we want to be picky, the traces of a 180° spin are different, there are generally two crossings, unless two wheels (on the same axle) loose contact with the road.

      For that to be true, the car can only have one axle?
