The central claim is attributed to anonymous sourcing, with no named individuals or official documents cited.

How well corroborated and evidenced the reporting is. Higher is better.

Craft45/100

The reporting lacks detail on the cause of the crash, who is responsible, and what happens next.

Context, balance and separation of fact from comment. Higher is better.

Hype61/100

The headline uses 'serious' and 'hour of delays' which is sensationalised for a live traffic report.

How far presentation runs ahead of substance. Lower is better.
