What might a driver observe if refrigerant is overflowing from their vehicle?

When refrigerant is overflowing from a vehicle, the driver might observe refrigerant overflow when the air conditioning system is on. This typically indicates that there is an issue within the A/C system, such as overcharging, a malfunctioning component, or a blockage that prevents the refrigerant from circulating properly. The overflowing refrigerant may manifest as frost or a hissing sound near the evaporator or compressor, indicating excess pressure and the resultant release of refrigerant.

The other options relate to different systems in the vehicle and do not directly pertain to the symptoms of refrigerant overflow from the A/C system. Coolant leaks from the engine indicate an issue in the engine's cooling system, condensation from the exhaust suggests normal operation of an engine, especially in colder conditions, and fluid leakage from damaged hoses could apply to various systems but does not specifically indicate refrigerant overflow.
