How the figures on this site are checked
A figure with the Verified mark is traced to the law or to the department that applies it. Here's how that works, and what to do if you spot a mistake.
Where do the figures come from?
In the guides, from the law as published, and from the public bodies that apply it, such as the Road Transport Department. Before a figure goes on a page, the passage that carries it is quoted word for word from its source. Other car guides, insurers and dealers are never a source.
What does the Verified mark mean?
Verified It means the figure under it is traced to the law or to the department that applies it. Each guide lists every source at its foot, with the date it was checked. The mark tells you where a figure comes from, not whether it applies to you.
What if the sources disagree?
Official documents sometimes contradict each other. Then the page gives each source's version and doesn't pick one. A figure the sources disagree on never carries the mark.
What does the road-tax calculator do?
It works out one amount from the rates in the law. Where the law leaves a point open, it uses the reading I judge most likely, and its fine print says so. Its result is marked "Worked out", because it's calculated, not quoted.
How current is a guide?
The "Checked" date beside my name is when the guide's sources were last checked. It isn't the date the page was last edited.
What happens when a rule changes?
When I learn that a rule has changed, I update the pages it affects.
Found a mistake?
Write to contact@motorscy.com and tell me the page and the figure. I check it against the source, and if it was wrong, I correct the page.
