Accessible Language Statutory Ballot Title Requirements

Under current law, the title board must set a ballot title for an initiative petition that is brief, does not conflict with another title for an initiative petition filed for the same election, and is in the form of a question that may be answered 'yes/for' or 'no/against' and that unambiguously states the principle of the provision sought to be added, amended, or repealed by the initiative. The act adds a requirement that the title board write a ballot title using accessible language, which means plain language that is understood by the widest possible audience. In determining whether a ballot title is written using accessible language, the title board may consider whether the title:Avoids using legal, technical, or specialized terminology when possible;Clearly identifies the principal change in law or policy proposed by the proposed statutory or constitutional amendment;Avoids unnecessary qualifiers, double negatives, and overly complex phrasing;Organizes clauses so that the effect of a 'yes/for' or 'no/against' vote is readily understood; andPresents necessary information within the ballot title in a logical and readable order.     In addition, current law requires that specific language appear in the ballot title for certain initiatives that increase or reduce tax revenue. For initiatives that reduce state tax revenue or local district property tax revenue through a tax change, this required language must appear at the beginning of the ballot title. For initiatives that increase tax revenue for any district through a tax change, this required language must appear directly after language required by the Taxpayer's Bill of Rights. The act modifies these statutory provisions so that the required ballot title language must only be substantially similar to the specific statutory language and may appear anywhere in the ballot title.     The act applies to initiative petitions submitted to the secretary of state for title setting on or after the effective date of the act.(Note: This summary applies to this bill as enacted.)

Traffic Safety Near Schools

The act defines school zones as all roadways within at least 1,000 feet of a school property boundary, except state highways unless they are designated as part of a school zone with the written approval of the Colorado department of transportation, and including school zones established before August 12, 2026, that are 200 feet or more from a school property boundary. A school zone must have appropriate signs posted indicating it is a school zone and that the penalties and surcharges within the school zone will be doubled.     The act allows a local government that has jurisdiction over a school zone to reduce the size of a school zone after first holding a public hearing, but the act does not allow a school zone to be reduced to less than 200 feet from a school property boundary. Additionally, the act does not prohibit local governments from expanding school zones to beyond 1,000 feet from a school property boundary.     The act limits requirements the state, a county, a city and county, or a municipality must complete regarding placing and using an automated vehicle identification system along a safe route to school.     The act allows a local government to designate a portion of a roadway immediately adjacent to a school property boundary as a school street and requires the local government to post signs indicating it is a school street if the local government has jurisdiction to do so. The local government may close a school street to traffic. If there is traffic on the school street, the maximum speed limit is 10 miles per hour and vehicles must yield the right-of-way to pedestrians, bicyclists, or micromobility users. The local government may suspend additional traffic provisions on the school street that endanger pedestrians, bicyclists, or micromobility users.(Note: This summary applies to this bill as enacted.)

Sunset Process Securities Regulation

The act implements the recommendations of the department of regulatory agencies (department) in its 2025 sunset review and report by continuing the division of securities and the securities board until 2037. In connection with continuing these entities, the act:Clarifies that deficiency letters and communications concerning a deficiency letter are not public documents that may be inspected under the 'Colorado Open Records Act';Requires that an investment adviser or an investment adviser representative doing business in Colorado must be licensed by the securities commissioner (commissioner) unless otherwise exempt;Specifies that the executive director of the department must consult with the securities board when appointing the commissioner; andUpdates statutory language to be gender neutral.     The act revises the process by which a cease-and-desist order is issued or a license is summarily suspended. Under the previous law, the commissioner issued a cease-and-desist order or conducted a summary license suspension by issuing an order to show cause as to why a cease-and-desist order or license suspension should not be issued. After appropriate notices were given, a hearing was scheduled with the securities board or an administrative law judge. At the hearing, it was determined whether to issue a cease-and-desist order or suspend the license and what form the order or suspension would take. The act changes this process to authorize the commissioner to issue a preliminary cease-and-desist order or a summary license-suspension order. If the person that is the subject of the order disagrees with the order, the person may request a hearing to resolve the issue. The hearing must take place within 45 days after issuance of the order unless both parties request an extension. The deadline for a hearing, with an exception, is changed from 35 days to 60 days. If a hearing is not requested within 15 days after issuance of the order, the order becomes final. The person that is the subject of the order must obey the order until a hearing is requested.(Note: This summary applies to this bill as enacted.)

orPerpetuate the discrimination of another LEP if both LEPs are subject to common administrative control or are agencies of the state.     In determining the site or location of a facility, an LEP may not make selections that:Exclude a qualified student with a disability from a facility or deny a qualified student with a disability the benefits of a facility, or that otherwise subject a qualified student with a disability to discrimination; orHave the purpose or effect of defeating or substantially impairing the accomplishment of the objectives of the program or activity with respect to a qualified student with a disability.     The act requires an LEP to:Adopt a disability rights grievance process that incorporates appropriate due process standards and that is satisfied by following the grievance procedures in section 504 of the federal 'Rehabilitation Act of 1973' and to designate at least one responsible employee to oversee compliance with the provisions of the act relating to discrimination and to serve as a point of contact for students and families;Make a reasonable modification to a policy, practice, or procedure when the modification is necessary to avoid discriminating against a qualified student with a disability on the basis of disability;Provide a reasonable accommodation to a parent with a disability who is seeking appropriate access to programs and activities for parents in relation to that parent's child;Ensure that a communication to a qualified student with a disability is as effective as a communication to a student without a disability and to furnish appropriate auxiliary aids and services where necessary to afford a qualified student with a disability an equal opportunity to participate in and enjoy the benefits of a service, program, or activity of the LEP;Ensure that a qualified student with a disability is not denied access to the LEP's services, programs, or activities because of facilities inaccessible to a qualified student with a disability;Provide a free and appropriate public education to each qualified student with a disability who is in the LEP's jurisdiction, regardless of the nature or severity of the student's disability, and if necessary, ensure adequate transportation to and from any placement premises;Provide for the free and appropriate public education of each qualified student with a disability with students without disabilities to the maximum extent appropriate to the needs of the qualified student with a disability; Place a qualified student with a disability in the regular educational environment operated by the LEP unless it is demonstrated that the education of the student in that environment with the use of supplementary aids and services cannot be achieved satisfactorily;Provide nonacademic and extracurricular services and activities in such a manner as is necessary to afford a qualified student with a disability an equal opportunity to participate in the services and activities;At least annually, identify and locate every qualified student with a disability residing in the LEP's jurisdiction who is not receiving a free and appropriate public education and take appropriate steps, with the permission of the qualified student with a disability and their parent, to evaluate the student; Ensure that a qualified student with a disability is free from harassment that is sufficiently serious to create a hostile environment or interfere with or limit the student's ability to participate in or benefit from the LEP's services, activities, or opportunities; andConduct evaluations and reevaluations of a student in the student's primary language, communicate with a parent with limited English proficiency in a manner that provides meaningful access to information, and provide interpretation and translation services for communication with a parent with limited English proficiency.     Subject to sufficient funding or resources, certain provisions of the act take effect, which:Allow the department of education (department) to provide training and technical assistance to LEPs about the requirements of the act;Establish a complaint process and specifies that the department may investigate and resolve complaints of alleged violations of the provisions of the act pursuant to the complaint process;Specify the circumstances under which an individual may file a complaint with the department;Allow the department to order specified remedies as determined necessary by the department to remedy violations occurring pursuant to the act and to prospectively ensure compliance, if the department finds a violation;

No later than December 31, 2026, the board shall adopt rules that establish procedures for the withholding of funds. The board must provide due process to an LEP before state funds are withheld.     The act prohibits an LEP from coercing, intimidating, threatening, or discriminating against any individual for the purpose of interfering with any right or privilege secured by the act, the federal 'Individuals with Disabilities Education Act', the 'Americans with Disabilities Act of 1990', the 'Exceptional Children's Educational Act', or the 'Protection of Students from Restraint and Seclusion Act' (anti-discrimination laws) because an individual:Makes, has made, or because an LEP believes an individual has made or will make, a complaint pursuant to an anti-discrimination law; orTestifies, assists, or participates in any manner in an investigation or proceeding regarding an allegation or complaint pursuant to an anti-discrimination law.(Note: This summary applies to this bill as enacted.)

Social Media Duty to Report & Search Warrants

The act requires an operator of a social media platform (operator) to ensure that its social media platform provides a streamlined process to allow law enforcement agencies to contact the social media platform. The process must be available to law enforcement agencies at all times and make available a staffed hotline for the purposes of:Receiving and responding to questions about search warrants;Acknowledging the receipt of a search warrant within 8 hours after receipt; andProviding status updates on search warrant compliance to a requesting law enforcement agency.     With certain exceptions, an operator must comply with a search warrant within 24 hours if certain conditions apply. A court may reasonably extend this time if the court makes a written finding that the operator or social media platform has shown good cause for the extension and that an extension would not cause an adverse result. The act sets forth enforcement options for the attorney general and district attorneys regarding operators' compliance with search warrants.     The act requires an operator to report to a social media platform user's (user's) local law enforcement agency within 24 hours if the operator's social media platform takes any one of certain described adverse actions against a user. A violation of the reporting requirement is a violation of the 'Colorado Consumer Protection Act'.     In current law, 'social media platform' is defined as an internet-based service, website, or application that satisfies certain criteria, including having more than 100,000 active users in Colorado. The act removes this criterion.     The act makes conforming amendments as necessary to Senate Bill 26-011, as enacted in the 2026 regular legislative session, to have Senate Bill 26-011 conform with the provisions of the act.(Note: This summary applies to this bill as enacted.)
