A new driving law came into force this month across Europe, and the UK is likely to adopt it.
Since July 6, speed limiters are legally required to be fitted on all cars in Europe, and since the UK has retained most EU laws for new cars, it is expected the UK will confirm to adopt the same rule. This is due to the fact that it's unlikely that EU-based manufacturers would make vehicles with additional different specifications just for the UK.
Confused.com add: "Vehicle Certification Agency will continue to follow EU regulations. This means that even though the UK has left the EU, speed limiters will still need to be fitted to new cars."
