Total Claims: 39
Claim 1
Independent Claim
100 words
A tachograph (20) comprising: means for receiving signals relating to the operation of a vehicle to which the tachograph is fitted from sensors on the vehicle; means for receiving a signal from which the location of the vehicle can be determined; means for deriving from the received signals data relating to the operation of the vehicle including the location of the vehicle with respect to time; and an electronic memory (28) in which the data is stored, access to the electronic memory being restricted such as to prevent selected data relating to the operation of the vehicle from being altered.
