Industrial vehicle comprising storage and retrieval hardware, a tag reader, a reader module, and a vehicle controller. The storage and retrieval hardware is configured to store and retrieve items from selected storage elements positioned along an aisle path, and the tag reader and the reader module cooperate to identify individual tags along the aisle path. The tag reader comprises two read antennas positioned on opposite sides of a longitudinal travel axis of the industrial vehicle, and the read antennas define respective read ranges and generate respective tag read signals when tags enter the respective read ranges of the read antennas. The tag reader and the reader module further cooperate to generate a vehicle direction signal when the individual tags are identified primarily with reference to tag read signals from only one of the two read antennas. The vehicle controller controls operational functions of the storage and retrieval hardware partially as a function of the vehicle direction signal.
