There are quite a few important gauges located on the dash of your car. The speedometer is one of the most important when driving. It measures how fast your car is traveling and displays that information via a needle and a dial. As your speed increases, the needle moves farther around the dial. You’ll find your speed denoted in both miles per hour (MPH) and in kilometers per hour (KPH). Miles per hour is the larger, outer ring of numbers and kilometers per hour is the smaller, inner ring of numbers. If the speedometer needle isn’t moving, have your car inspected immediately (and drive slowly).
