kilométeróra

The kilométeróra, often referred to as a speedometer in English, is an instrument panel device that displays the instantaneous speed of a vehicle. It is a crucial component for drivers to monitor their rate of travel and ensure compliance with speed limits. The unit of measurement displayed is typically kilometers per hour (km/h).

Modern kilométeróras are usually digital, presenting speed as a numerical readout. Older vehicles, and some contemporary models for aesthetic reasons, feature analog kilométeróras with a needle that moves across a dial calibrated to indicate speed. The mechanism behind the kilométeróra has evolved significantly. Early versions relied on mechanical cables driven by the vehicle's transmission. Today, electronic sensors are more common, often using the anti-lock braking system (ABS) wheel speed sensors or a dedicated speed sensor on the transmission or driveshaft.

The kilométeróra is often integrated into the instrument cluster alongside other vital gauges such as the fuel gauge, tachometer, and engine temperature gauge. In many jurisdictions, accurate functioning of the kilométeróra is a legal requirement for vehicles. Beyond legal compliance, the kilométeróra plays a significant role in safe driving practices by allowing drivers to maintain appropriate speeds for road conditions and traffic flow.
