Overview
- Ministers said the government‑commissioned TRL glare study will be published next week after real‑world night‑driving tests using instrumented vehicles and machine learning.
- The Department for Transport confirmed tougher lighting rules that include mandatory automatic headlamp levelling taking effect in September 2027 to allow manufacturers time to redesign.
- Preliminary research indicates road geometry is the leading factor in glare events, with vehicle type—particularly higher‑riding SUVs—the next most significant contributor.
- DVSA has stepped up market surveillance to intercept illegal retrofit headlamp bulbs for on‑road use, with offenders facing fines of up to £1,000.
- Officials noted high public concern and non‑collision harms despite police data showing no rise in glare‑related crashes, and they plan proposals at the UN plus a Euro NCAP vision protocol for 2029.
