Your car will probably stop if your engine locks up while you’re driving. You might also notice that your engine sounds very rough or makes a strange knocking
noise
, both of which can indicate a seized engine.
The most common reason that an engine will seize while driving is a lack of oil. As such, you might notice your oil light come on before your engine seizes up. Other symptoms of a seized engine include poor acceleration and the knocking noise that was previously mentioned.
