I looked at the photos in both articles. It seems to be a single vehicle accident in good weather and broad daylight. I don't see evidence of another vehicle or hard breaking.

Reminded me of this accident near Ottawa. Chinese tourists were killed. Chinese driver from NY was charged with careless driving.
