The conditions for the compatibility between the taximeter and the distance signal generator shall be specified by the manufacturer of the taximeter.

If there is a supplement charge for an extra service, entered by the driver on manual command, this shall be excluded from the fare displayed. However, in that case a taximeter may display temporarily the value of the fare including the supplementary charge.

If the fare is calculated according to calculation mode D a taximeter may have an additional display mode in which only the total distance and duration of the trip are displayed in real time.

All values displayed for the passenger shall be suitably identified. These values as well as their identification shall be clearly readable under daylight and night conditions.

If the fare to be paid or the measures to be taken against fraudulent use can be affected by the choice of functionality from a pre-programmed setting or by free data setting, it shall be possible to secure the instrument settings and data entered.

The securing possibilities available in a taximeter shall be such that separate securing of the settings is possible.

The provisions in point 8.3 of Annex I apply also to the tariffs.

• The total distance travelled by the taxi;

• The total distance travelled when hired;

• The total number of hirings;

• The total amount of money charged as supplements;

• The total amount of money charged as fare.

The totalised values shall include the values saved according to point 9 under conditions of loss of power supply.

If disconnected from power, a taximeter shall allow the totalised values to be stored for one year for the purpose of reading out the values from the taximeter to another medium.

Adequate measures shall be taken to prevent the display of totalised values from being used to deceive passengers.

• distance of the trip;

• duration of the trip;

• time of the day;

• date;

• day of the week.

If properties of the taxi are important for the correctness of the taximeter, the taximeter shall provide means to secure the connection of the taximeter to the taxi in which it is installed.

For the purpose of testing after installation, the taximeter shall be equipped with the possibility to test separately the accuracy of time and distance measurement and the accuracy of the calculation.

A taximeter and its installation instructions specified by the manufacturer shall be such that, if installed according to the manufacturer’s instructions, fraudulent alterations of the measurement signal representing the distance travelled are sufficiently excluded.

The general essential requirement dealing with fraudulent use shall be fulfilled in such a way that the interests of the customer, the driver, the driver’s employer and the fiscal authorities are protected.

A taximeter shall be designed so that it can respect the MPEs without adjustment during a period of one year of normal use.

• the timekeeping shall have an accuracy of 0,02 %;

• the correction possibility of the clock shall be not more than 2 minutes per week. Correction for summer and wintertime shall be performed automatically;

• correction, automatic or manually, during a trip shall be prevented.

• Distance travelled:

  • kilometres;

  • miles, in those Member States to which Article (1)(b) of Directive 80/181/EEC applies.

• Time elapsed:

  • seconds, minutes or hours, as may be suitable; keeping in mind the necessary resolution and the need to prevent misunderstandings.
