Details

This report outlines the findings of research conducted to test the clarity of revised Highway Code wording and drivers’ understanding of:

  • the difference between automated vehicles and vehicles with advanced driver assistance systems, in terms of vehicle capability and driver responsibilities
  • their residual responsibilities when an automated vehicle is driving itself
  • what they can and cannot do when an automated vehicle is driving itself

The draft Highway Code text used in this research was a revised version of text included in the Department for Transport’s (DfT’s) April 2021 consultation on Safe use rules for automated vehicles. The revisions made to the text took account of responses received to consultation.

The text which was used for this cognitive research was then further amended on the basis of the research findings to produce the final text for the Highway Code.

The research was commissioned by DfT and conducted by BritainThinks.
