A travel distance indicator having an elongated distance scale and a slidable marker member straddling the distance scale. A front leg of the marker member has a front projection which slidably fits within a channel extending lengthwise across a front surface of the distance scale. The channel stops short of each end of the distance scale to prevent the marker member from being inadvertently slid off an end of the distance scale. Pictorial symbols are removably attached to the front surface of the distance scale in the order in which various stops and observations are represented by the symbols are to occur. A marker in the shape of a motor vehicle is fixed to the marker member to give an appearance of a vehicle traveling along a road strip that is part of the distance scale. The road strip includes graduations which divide the distance bar into equal portions to represent equal portions of miles of travel.
