My Lords, once again I am grateful for the contributions in this group. One of the central functions of the Bill is to clarify how liability is to be handled in a world of
self-driving vehicles. This is a complex area and I reiterate my thanks to the Law Commissions for their many years of work developing the approaches that we are discussing today. I am grateful also to noble Lords for their insightful contributions and scrutiny on this critical issue.
Amendment 55G, tabled by the noble Lord, Lord Liddle, would require a study to be conducted on human reactions to transition demands. Before I address that proposal, I will respond to his specific point about how liability applies during the transition period. The Bill is explicit that the authorised self-driving entity remains responsible for the behaviour of the vehicle until the transition period expires. After that period, liability shifts to the driver. However, it is a misconception to imagine that manual control will simply be forced on the driver at the end of that period. Clause 7(3)(e) mandates that vehicles be capable of dealing safely with a situation in which the user-in-charge fails to assume control. In other words, although legal responsibility shifts back to the driver once the transition period expires, the vehicle is still required to bring itself to a safe stop without their intervention. A vehicle that was unable to do that would not be authorised.
On the amendment itself, there is already a considerable body of evidence on response times to transition demands, particularly using simulators. Much of that underpins the international automated lane keeping systems regulation to which I referred earlier. There are a number of additional research projects in this space already in development across the Department for Transport and its agencies. For example, one such project looks to explore what activities a user-in-charge can safely perform while their vehicle is driving itself. This is a question that will also require ongoing monitoring and evaluation over time. We will be able to mandate information sharing from authorised self-driving entities to further expand this evidence base as the technology develops.
