An electronic trip meter for an automotive vehicle comprises a memory circuit to store sector distances between a start point and intermediate and final destinations, a distance presetting circuit to determine alarm points near to and before intermediate and final destinations, a counter to count the actual distance travelled from the last destination, a comparator to output a signal from the time when the value in the counter becomes equal to that in the distance presetting circuit until the time when the value in the counter becomes equal to that in the memory circuit, an alarm device driven by the comparator output signal, and a display device. Such an electronic trip meter displays the remaining distance to the next destination while the comparator is sending out an output signal; that is, at any intermediate points in between an alarm-point and the next destination. At other times the display shows a value representative of the total distance travelled. Additionally, the alarm sound is kept ringing in between the alarm-point and the next destination.
