What Is an Odometer?
An odometer is a device that records the total distance a vehicle has traveled. It is typically located on the dashboard and displays mileage in miles or kilometers. Odometers help owners track vehicle use and plan maintenance.
How Does an Odometer Work?
Modern odometers are electronic sensors linked to the vehicle's wheel speed sensors. Each rotation of the wheel triggers a count that is converted into distance. Older models used mechanical cables connected to the transmission. The system stores cumulative mileage in the vehicle's computer.
Why Is the Odometer Important?
Odometer readings affect resale value, insurance rates, and service schedules. Accurate mileage helps buyers verify a vehicle's history and detect potential rollback fraud. According to the National Highway Traffic Safety Administration, tampering with an odometer is illegal and can lead to fines and penalties. Always check the odometer when buying a used vehicle.
