Has driving become less enjoyable for you due to bothersome headlight glare?
In the realm of road safety, a significant concern has been rising: headlight glare. This issue, particularly prevalent among caravanners, has been the subject of much discussion and research in recent times.
The Department for Transport (DfT) acknowledges the problem, commissioning a comprehensive study into headlight glare, which is being conducted by leading transport researcher TRL. The project aims to identify the sources of light to which a typical motorist is exposed.
One of the key contributory factors to headlight glare is incorrect headlight alignment. It is, therefore, crucial to have headlights checked and adjusted by a professional according to manufacturer and legal standards. RAC data shows many vehicles fail MOT due to misaligned headlights, which is a key cause of glare.
Vehicle choice matters too. Many caravanners use taller SUVs, which tend to have higher-positioned headlights, causing glare for drivers in lower cars. Ensuring your own vehicle's headlights are correctly aligned can help mitigate this issue, especially when using or towing a caravan.
Modern LED headlights, while brighter and more focused, may contribute to glare issues. This is because current international standards for headlights have not fully caught up with newer lighting technologies like LEDs or xenon. More research and regulatory updates are needed in this area.
Several solutions and recommendations have emerged to reduce headlight glare. UV & glare reduction films or coatings are one such option. Some caravan-related services offer protective wraps that reduce glare and UV exposure, which can help reduce driver fatigue caused by glare.
Sunglasses with tinted lenses designed to shield eyes from glare are also recommended for drivers, especially on long road trips with changing light conditions. These can improve comfort and visibility.
It's important to note that it's not just the technology, but also personal factors that can contribute to headlight glare. Conditions such as cataracts or age-related macular degeneration can affect a person's ability to handle glare. A trip to the optician is recommended if experiencing problems with glare.
Recent surveys by driving organizations such as the RAC and the AA have revealed that a majority of drivers find at least some car headlights too bright. In fact, almost all drivers surveyed find some headlights too bright, according to a RAC study in February 2025. Moreover, 61% of drivers who say they are affected by headlight glare believe the problem has worsened in just 12 months.
Driving organizations have been lobbying for more research into headlight glare, with questions raised in the House of Commons about whether there were any plans to fund independent research into the potential safety implications of headlight glare. In March 2025, Parliamentary Under-Secretary at the DfT Lilian Greenwood MP stated that the Government has commissioned independent research to better understand the root causes of headlight glare and develop potential countermeasures.
In conclusion, caravanners should ensure their vehicle's headlights are properly aligned and compliant with standards, consider the lighting type they use, and employ additional measures like UV/glare reduction films and sunglasses to minimize headlight glare and improve safety and comfort while driving at night or in low-light conditions. Regular sight tests at the optometrist and maintaining a clean windscreen and spectacles are also essential in combating glare.
- The transportation industry, particularly the car-maintenance sector, is being encouraged to address the issue of headlight glare, with the Department for Transport (DfT) commissioning a study to identify contributing factors.
- In the realm of car-maintenance, ensuring that cars, especially tow cars used for caravanning, have properly aligned headlights according to manufacturer and legal standards is a crucial step in reducing headlight glare.
- To address the issue of headlight glare during driving, several lifestyle adjustments can be made, such as using UV & glare reduction films or coatings, wearing sunglasses with tinted lenses, and maintaining regular sight tests at the optometrist.
