Laura siempre maneja su coche demasiado rápido en la llave rueda autopista batería

Here the correct word to complete the sentence is autopista, which means highway (or motorway) in English.  

A highway is a circulation track for automobiles; its principal characteristic is that it admits a considerable volume of traffic, differing from a conventional road.

Generally a highway has more than one lane for each direction with separate roads and must be fast and safe for the drivers.

In addition, autopista is a feminine and singular noun, and according to the spanish grammar, this kind of nouns must be preceded by the definite article la.

Therefore, the right answer is:

Laura always drives her car too fast on the highway.

The other words are not correct, because:  

Llave means key: generally a small piece of metal, shaped with incisions that fit the wards of a particular lock, and that is inserted into the lock and turned to open or close it.

Rueda means wheel: a circular object, of little thickness with respect to its radius, which can rotate on an axis.

Batería means Battery, generally it is an electromagnetic device capable of accumulating electric power and supplying it.
