Four people were pronounced deceased at the scene, while one passenger of the Chevrolet was taken to hospital with life-altering but non-life-threatening injuries.

Why this leaning score
The article presents a neutral, fact-based report with objective language, avoiding emotive or sensationalizing tone; however, the inclusion of phrases like 'wrong lane' might subtly emphasize the driver's responsibility, but this is a relatively minor and ambiguous phrasing.
Written under an earlier scoring contract, which gave a paragraph
