NHTSA recommends that car seats be replaced following a moderate or severe crash. Car seats do not automatically need to be replaced following a minor crash.
A minor crash is one in which ALL of the following apply:
-The vehicle was able to be driven away from the crash site.
-The vehicle door nearest the car seat was not damaged.
-None of the passengers in the vehicle sustained any injuries in the crash.
-If the vehicle has air bags, the air bags did not deploy during the crash
-There is no visible damage to the car seat.
NEVER use a car seat that has been involved in a moderate to severe crash. Always follow manufacturer's instructions.
