Your car could have overheated due to a loss of coolant/antifreeze. This could be from a faulty hose clamp to a leak with your water pump. The only way to know for sure is to have it checked to make sure you have all the information about your vehicle. When ever your car starts to overheat you need to pull over as soon as it's safe and turn off your engine. Overheating can lead to damage of your engine and possible engine failure.
