Odometer Day

May 12 is a holiday dedicated to a device without which it is impossible to imagine modern transport. Odometer Day celebrates the equipment that shows you how far your vehicle has traveled and whether it’s time for maintenance again.

History

The distance a vehicle has traveled is measured using an odometer, which can be mechanical or electromechanical. While the exact inventor is unknown, similar measuring devices were used in Ancient Greece, the Roman Empire, and various Asian civilizations. Early devices were made of wood, with the human pace serving as the measuring unit. In 1847, William Clayton invented the road meter, and in 1903, the Warner brothers were the first to install an odometer resembling its modern form in a car.

Interesting Facts

The word “odometer” is derived from two Greek roots, meaning “measure of the way.”

  1. Modern cars are equipped with trip meters, which can be reset when you need to start measuring again. This differs from the odometer, as the odometer’s total cannot be changed.
  2. Odometer readings are recorded during a vehicle’s technical inspection, which is required by law to be performed regularly.
  3. If you are buying a used car, pay close attention to the odometer reading. Sellers sometimes manipulate the reading to increase the vehicle’s value.

Take care of your vehicle, monitor its condition, and perform timely repairs. A car is a convenient means of transportation, but its systems must be well-maintained to ensure it runs smoothly.
