you probably have a blown head gasket
The overflow tank is either cracked or its overheating and leaking from the cap
You may have a bad radiator cap.
It is leaking coolant or the radiator cap is faulty.
well, if by fluid u mean coolant than yes. If coolant is leaking, there wont be anything to cool the engine temperature. Replace the cap, there very cheap.
A bad or incorrect radiator cap.
if it is a creamy color coming from a radiator look in the oil by looking at the inside bottom of the cap,if it is creamy too,then you have a blown head gasket. that creamy color is water and oil mixed oil mixed in with the water, you got a blown gasket
Is it too full? Well some vehicles are equiped with a little hose that will let coolant out if there is too much or too much pressure, but not all vehicles will have it. (If you are talking about the overflow tank, if the radiator cap is leaking, check to see if the cap is in good condition)
Bad head gasket? Bad thermostat? Defective radiator cap?
Replace it, should only coast a few bucks at auto parts store.
It will be safe to drive short distance as long as the car does not over heat. You can top up the engine coolant or use water/coolant mixture till you fix the problem which could be leaking hose pipe. leaking radiator or faulty radiator cap

Coolant leaking into engine oil? Leaking head gasket Run engine to normal operating temperature pull oil dipstick and let a drop fall onto hot part of engine - oil will smoke coolant will sizzle
