Technical information about this website’s accessibility

This website is partially compliant with the Swedish accessibility regulations, due to the non-compliances listed below.

Non-accessible content

Documents on

VTI publications and documents available on are not fully accessible.

In our VTI publications, there are shortcomings in forms of:

  • Complex tables with wrong or missing headers and problems with merged or split cells, causing reading order problems. There are also other element errors in tables.
  • In several cases, Alt texts for photos, diagrams, and figures are missing.
  • Lack of titles and labels in Charts.
  • Low contrast between color and background in diagrams and figures.
  • Error in language settings.
  • Equations and formulas without description or alt text. That could potentially be a problem for screen readers who can't decipher the characters.

Pages on

Problems when using without vision:

  • Headings and heading levels are not always used correctly, causing reading order problems. For example, headings are used in the wrong order, or bolded text is used as headings.
  • Sometimes alt text is missing for images, or sometimes, alt text is used on images that are decorative and do not add meaning.
  • There are videos on the website that lack visual interpretation and in some cases subtitles.
  • The sorting order in the search function for Publications and Employees is not consistently designed.
  • The website retrieves information from other websites via iframes. Some of the loaded websites are not accessible. This includes, for example, our press room.

Content that’s not within the scope of the accessibility regulations

VTI invokes exceptions for unreasonably burdensome adaptation according to § 12 of the Act on accessibility to digital public services in the ongoing work with our VTI publications. The publications are extensive, with many charts and tables, and each publication takes an estimated three working days to adapt for accessibility. We publish around a hundred publications a year.

The publications are partly accessible, but there are shortcomings as mentioned above. We consider fully adapting our publications for accessibility to be unreasonably burdensome regarding our size, our task, and the resources required in relation to the benefits it entails for people with disabilities.

We invite anyone who cannot assimilate the content of a VTI publication to contact us and we will make a special effort to improve the accessibility of the publication. See contact information above under the heading "Reporting accessibility problems with this website".
