Terms of Use

Last updated November 2026. Plain-language terms that have not been reviewed by a lawyer.

Information, not legal advice

This website is an independent legal information resource. It is not a law firm, does not provide legal advice, and using it or contacting us does not create an attorney-client relationship. Talk to a licensed Colorado attorney about your situation.

The guides summarize Colorado statutes in general terms. They do not describe how the law applies to any person's facts, they may not reflect the most recent amendments or court decisions, and they are not a substitute for advice from a lawyer licensed in Colorado.

No attorney-client relationship

Reading this site, using its tools, or sending a message through it does not create an attorney-client relationship with anyone. Nothing you send is confidential or privileged. Do not send information about a legal matter.

Accuracy and changes

We work to keep statute summaries accurate and mark each guide with the month it was last checked, but laws change and errors happen. Always verify the current text on the Colorado General Assembly's website and with a licensed attorney before relying on anything here. We may update or remove content at any time.

Interactive tools

The BAC explorer and the questions checklist illustrate what the statutes say. They do not estimate anyone's alcohol concentration, predict the outcome of a case, or recommend any course of action.

No endorsement

We do not recommend, rank or refer to particular lawyers or firms, and we are not affiliated with any court, agency or law firm. Links to official and third-party sites are provided for convenience; we are not responsible for their content.

Acceptable use

Do not use the contact form to send spam, unlawful content, or other people's personal information. Do not attempt to disrupt or probe the site's security.

Limitation of liability

The site is provided "as is." To the extent permitted by law, the operator is not liable for any loss arising from use of, or reliance on, the information here.

Questions about these terms can be sent through the general inquiry form.
