There are no proposals for mandating speed limiters on all new vehicles in the UK. Vehicles sold in Northern Ireland will be required to have speed warning systems, known as Intelligent Speed Assistance (ISA), installed on all new registrations from July 2024. The Department for Transport is currently considering a package of new vehicle technologies, which includes ISA, that are designed to aid road safety. We will consider whether to make these technologies compulsory in new vehicles sold here once the new GB type approval scheme is in place. This is scheduled to be ready by mid-2022.
