Reading the article, sounds like they have a fuel tanker crash problem. There's been several in the last 3-4 years all involving busses and fuel tankers. I get there's awful road conditions and few regulations but it's suspiciously common for a bus to hit a fuel tanker at least once a year.
Especially, judging by the photos, in such an open space. I've never driven in the desert so correct me if I'm wrong, but it seems like there's enough visibility to prepare for crossing paths with another vehicle? I'm sure rolling off-road into the sand is better than ramming into a fuel truck.
Here in Canada I'd suspect the number is fairly quite low if we're talking independently. Cost of everything is high and wages are comparatively low for the most part. Maybe once you look at ages 45 and up its less bad but 30-45 probably less than 50%
