Heavy rain contributed to a series of accidents, while a broken oil line on the Alfa Romeo of Mario Tadini led to so many wrecks in the chicane out of the tunnel it was almost impassable.

[1] The Mercedes-Benzes of Louis Chiron, Luigi Fagioli, and Manfred von Brauchitsch, as well as Bernd Rosemeyer's Typ C of newcomer Auto Union, were all eliminated.

He was followed by Achille Varzi and Hans Stuck, both for Auto Union.
