Why are there always puddles under car crashes?

    There isn't ALWAYS a puddle under cars involved in accidents. A puddle forms under a vehicle only if one of the systems containing fluid is damaged significantly enough that it leaks. The most common puddle creator is the cooling system. When a vehicle rear-ends another vehicle with enough force, the radiator** of the vehicle in the rear gets damaged causing coolant to leak out onto the pavement creating a puddle. Other potential fluid systems that can result in puddles are the windshield washer system, the power steering system, the lubrication/oil system, the transmission system (both manual and automatic), and the differential or transaxle system. If the accident is only minor then you will most likely not find a puddle under either of the vehicles.

    ** Heat exchanger in the very front of the vehicle responsible for cooling down the fluid that is circulated through the engine block by the water pump.

    While puddles after crashes are quite common, there aren't *always* puddles.

    Frequently, a car crash results in radiator damage. This causes a puddle of leaked coolant on the ground under the front of the vehicle with the damaged radiator. Much less frequently, a gas tank will get damaged in a crash which then results in a gasoline puddle under the rear of the damaged vehicle.

    cars store various fluids all around them. the most common to spill in an accident is radiator fluid. the radiator is at the very front of the car and quite fragile. breaking it means that the fluid spills out. there's also things like windshield wiper fluid stored at the front, fuel stored at the back or even brake and steering fluid stored throughout the car. if any hoses, pumps, tanks or other parts that use these fluids break the fluids spill out.

    Well cars have lots of fluid in various places a wreck will surely effect one of them.My first thought was the car really had to go sorry.
