How do the traffic lights work at Passo Stalle?

Staller Saddle, or Passo Stalle, is a seriously cool international pass sitting way up at 2,061m (6,761ft), right on the border between Austria and Italy. It's your ticket between the Defereggen Valley in Austria's East Tyrol and the Valle di Anterselva in Italy's South Tyrol, carving through the stunning High Tauern range.

This road is paved and signed, but hold on tight! The Italian side gets super narrow, making it one of the Alps' most challenging drives. It's so tight that they use a synchronized one-way system with traffic lights to keep things flowing.

Think of it like this: from the Austrian side, you get the green light for the first 15 minutes of every hour. Coming from the Italian side? Your green window is from the 30th to the 45th minute. Overtaking? Forget about it! And running a red light? Seriously dangerous.

The Italian side, aka SP44, is where things get wild. Crazy narrow, blind corners everywhere, and some seriously steep sections. Big rigs, buses, and caravans are a no-go. Some spots are so tight, even squeezing past a cyclist can be tricky. This stretch is only open from May to October, and even then, just between 5:30 AM and 10:15 PM.

The Austrian side (L25) is generally wider and a bit less steep. But don't get too comfy! After Erlsbach (1,549m), the road kicks up with some consistent inclines. Pro tip: gas is usually way cheaper in Austria, so fill up in St. Jakob in Defereggen before you cross into Italy!

Is it dangerous? The road itself is in good shape, but the real danger is the lack of space and that tight timing. Waiting 45 minutes for a green light can tempt some drivers to take risks, but those blind corners on the Italian side leave zero room for error. Heavy rain or landslides can also shut things down, even in summer.
