# 20mph Zones

Lower speed limits are usually requested for safety reasons, not least for children and cyclists -see more in a publication from the [Royal Society for the Prevention of Accidents](https://www.rospa.com/siteassets/pages/road-safety/road-safety-resources/free-road-safety-information/drivers/a-guide-to-20mph-limits-1123.pdf). There is also an insurance perspective from [Howden Insurance](https://blog.howdeninsurance.co.uk/20mph-zones-how-effective-are-they/).

Potential obstacles include:

* County Highways unwillingness
* Police objections
* Funding

There is national guidance at <https://www.gov.uk/government/publications/setting-local-speed-limits/setting-local-speed-limits>, but each county will have its own policy in this matter.

There will be examples of successful approaches shown here over time, but speaking to your county or unitary councillor can be a first step to understanding the local process.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://wiki.greatcollaboration.uk/knowledgebase/landscape/20mph-zones.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
