To ask the Secretary of State for Transport, what assessment he has made of the adequacy of progress on the implementation of the [a] headlamp aiming criteria and [b] requirements for mandatory automatic headlamp levelling agreed by the United Nations Economic Commission for Europe’s road vehicle lighting expert group in April 2023.

Progress is being made at the United Nations to change the relevant regulations to introduce revised headlamp aiming criteria and mandatory headlamp levelling. The administrative process and transitional provisions permit sufficient time for vehicle manufacturers to redesign their products and adapt the manufacturing process to ensure conformity with the tighter tolerances, and is expected to come into effect in September 2027.
