An odometer is the gauge that records how many miles a vehicle has driven over its lifetime. On a commercial truck, it’s a basic but important figure — mileage drives maintenance schedules, resale value, and record-keeping.
Accurate mileage also feeds the numbers a dispatch operation runs on, from trip distances to the rate per mile math that decides whether a load pays. Odometer readings are a routine data point in tracking how hard a truck is being worked.
