It is best to leave the engine to cool and then find the source of why it overheated before continuing driving. May be as simple as a lack of coolant that has caused it but could be fan not kicking in when it should to cool the radiator. If you don't need to drive far to get it home if you are out then let it cool down first and get it home, then see if you can trace the problem. If you overheat the engine to much you can cause some damage that can be costly to repair.
