Quick answers

Which local authority or corridor rules matter for this type?

Start with the local lens: type approval, operator licences and the hubs named on this page — not a single global checklist.

Is this a buying guide?

No. Tool-Lifes /vehicles is an educational atlas. It explains history, systems and culture without affiliate rankings.

Are the scores official?

No. The six scores are relative editorial 0–100 marks across the twenty-four types on this site.

Where do the photos come from?

Lead images resolve from Wikimedia Commons via Wikipedia titles on the English masters, with licences recorded on the credits page.

Why metric units?

Metric is the default. Regional notes (US customary, local brand culture) appear in culture and market chapters.

How is this different from a wiki article?

Each type gets seven fixed-depth chapters, comparable scores and cross-type labs — structured for browsing, not a single freeform page.

Icons are not always the best sellers — they are the ones that stuck in culture, engineering lore or both.
