Adelaide's O-Bahn Goes 365 Days Without a Car Crash

Adelaide's O-Bahn busway just hit a milestone nobody expected: a full year without a car crashing on its bus-only track.

The guided busway opened in 1986 and was designed exclusively for specially fitted buses that use small guide wheels to travel up to 80 kilometers per hour. Despite clear warning signs, cars regularly ended up on the concrete track, crashing into the middle barrier before reaching the next exit.

Dan Schmidt from the Adelaide Mail satirical website has been counting the days since the last incident. For over 15 years, he watched cars get stuck every 28 to 60 days on average.

"A month ago, we realized it's actually getting quite high," Schmidt said. He credits their O-Bahn promotion (or "O-Bahn-otion" as he calls it) with helping raise awareness about staying off the track.

The last crash happened on April 2, 2025, when six teenagers allegedly drove a stolen car on the track for 2 kilometers. Since then, 365 days have passed without incident.

The O-Bahn connects Gilberton to Modbury in Adelaide's northeastern suburbs. Similar guided busway systems operate in Essen, Germany (which inspired Adelaide's design), Nagoya, Japan, and Cambridgeshire in the UK.

Michael Pretty from the Bus Preservation Association of South Australia says the crashes aren't caused by track problems. Car drivers simply ignore warning signs.

The track used to have "sump-busters" that would damage the oil pans of cars attempting to enter. Modern cars with different suspension systems now drive right over these deterrents, which is why drivers only come to grief when they hit the middle barrier.

The Bright Side

To celebrate the anniversary, Schmidt and his colleague Trent Bartlett recorded a live podcast from a bus traveling on the O-Bahn. The milestone represents more than just accident-free days; it shows how community awareness and a little humor can actually change behavior.

Whether it's a genuine record for the 40-year-old busway is still being confirmed by the Department for Infrastructure and Transport, but longtime observers believe it's the first time the track has stayed car-free for this long.

Sometimes the best progress is simply people paying attention to the signs.
