Allow me to answer on behalf of Jürgen & GJ (just because I had the pics at hand
).
Obviously all tracks aren't equally clear and partials can make it more complicated but as a rule it's quite simple. Snakes employ two main forms of movement, depending on the species.
Sidewinding snakes such as Cerastes leave a series of separate imprints, the head clearly showing in each. The snake obviously moves in the direction the head is pointing.

Other snakes, in the middle east at least encompassing among others all the colubrids, employ an undulating form of locomotion leaving a continuous serpentine track. In moving forward they push the sand backwards leaving small mounds at the edge of the track showing the direction of movement.
