Perhaps, though I once broke a 1L bottle of ammonium hydroxide (a strong solution of ammonia) in the lab. We literally couldn’t go in the room for 15 min. That was just 1L of not 100% ammonia, and we had a door where we could get out. Even if the ammonia isn’t flammable, you might kill occupants of a car with what is effectively a poison gas.
