Vehicle Headlight Glare Standards

Debate between Scott Arthur and Peter Lamb

Wednesday 29th October 2025 Westminster Hall

[Peter Lamb]

Although the researcher involved did not look into particular age groups, I think we all know that on balance, it is often older citizens who are far more inclined to feel the issue of headlights and problems with driving in general. When looking at the numbers, which show the scale of people who are simply staying at home because they no longer feel safe in the road, we realise that something clearly has to be done. The overwhelming majority of those who say that they are no longer driving at night, or would not drive if they had the choice, cite headlight glare as the primary reason.

[Dr Scott Arthur (Edinburgh South West) (Lab)]

I congratulate my hon. Friend on securing his first Westminster Hall debate. I thought this was an issue of personal annoyance until I met Alan, an old colleague from Heriot-Watt University, who said he found it difficult to go out in the evening and was not looking forward to winter. He is a young man—even younger than me—so does my hon. Friend agree that we need more research to fully understand the negative impacts of these lights?

[Peter Lamb]

Certainly, there is probably work to be done in general around how transport impacts social isolation, and particularly at different times of day. We know the impact that losing bus routes has had on rural communities, and the age brackets for which that causes huge problems. Transport for many people is an essential part of daily life; they do not have the options that those of us lucky enough—I say lucky—to live in an urban area have available to us. We have to think of the enormous impact that this issue has not only on convenience, but on someone’s ability to get through life.

There are options available to drivers to reduce headlight glare. They can try keeping their windscreen and glasses clean; they can adjust mirrors to reduce glare; and they can ensure that their own headlights are properly aligned and avoid buying SUV-type vehicles. [Interruption.] Well, they could. Although all those things would see an improvement in our roads, driving-related law in the UK should not be reliant on voluntary measures by drivers. The law relating to driving begins from the starting point that every vehicle is a lethal object and rigid rules are required to manage that risk.

The track record of accidents stemming from headlight glare is now sufficiently clear, but it is time for that to be recognised in law with a new standard to ensure that headlights in the United Kingdom do not exceed safe levels of brightness. I am glad that the Department for Transport appears to have recognised that, with the Transport Research Laboratory having been commissioned last year to study the impacts of headlight glare. I understand that research was supposed to have been completed in the spring, but it has not yet been published. Despite that, there have been positive noises, certainly in recent days, about headlight glare being addressed, in part through the new road safety strategy. I hope that hon. Members will receive assurances about that from the Minister, and I hope that this debate will help to maintain pressure for the action that our constituents deserve at the earliest opportunity.
