Caltrans’ website uses Alternative Text “ALT” and/or “TITLE” attributes. ALT/TITLE attributes provide a written description of the image, which is accessible to screen readers, and visible when the mouse is placed over an image. This is also useful for people who have images turned off on their browser, in which case a description will display in place of where the image used to be.

Font Size

Caltrans’ website is mobile optimized and uses default fonts that allow users to customize the size based on their preference.


Located at the top of each page (except the home page) and directly below the main navigation, breadcrumbs provide a trail of where you are and where you have been. Breadcrumbs make it easier to navigate your way back to the root folder.


Our website is configured using highly accessible color contrast combinations. Adjusting contrast can be done by the user customizing their own web browser.

Examples of customization are:

  1. Invert colors
  2. Grayscale
  3. Differentiate without color
  4. Increase contrast
  5. Reduce transparency
  6. Display contrast
  7. Cursor size
