An odometer is a device used in vehicles to measure the distance traveled. It is typically found on the dashboard and displays the total miles or kilometers driven. Odometers can be mechanical or digital, and they help drivers keep track of their vehicle's usage for maintenance and fuel efficiency. In addition to standard odometers, there are also trip odometers that allow drivers to measure the distance of individual trips. This feature can be useful for tracking specific journeys or for calculating fuel consumption over shorter distances. Both types of odometers play a crucial role in vehicle management and maintenance.
