As evenings grow darker, new research reveals that bright headlights are the leading cause of nervousness among UK drivers. We also share tips on how to stay safe on the roads and reduce glare.

With the clocks having recently gone back, darker evenings are here – and for many drivers, so is headlight glare. In fact, four-in-five drivers (82%) are concerned about being dazzled by oncoming headlights this winter, according to new research from the RAC.

The breakdown service’s study highlights that the brightness of headlights is the leading reason drivers feel nervous at night. Among those who admitted to feeling uneasy after dark, three-quarters (75%) said it was due to dazzling headlights.

By comparison, 63% cited difficulty spotting hazards, 41% said judging the speed of other vehicles was harder, and 33% reported problems judging distances.

Over the past few years, complaints about blinding headlights have prompted the RAC, The College of Optometrists, road safety charity IAM RoadSmart, and Baroness Hayter to push for government-led research. This investigation, conducted by transport experts TRL, is due to be published soon.

The impact on driving habits

Earlier research shows that one-in-four drivers who find headlights too bright are driving less as a result, while another 22% continue to drive at night because they have no alternative.

“For many, darker evenings mean coping with overly bright headlights, which can cause discomfort and dazzle,” said RAC senior policy officer, Rod Dennis. “While brighter lights improve visibility, the fact that glare is the top cause of nervousness shows this is an issue that must be addressed.”

Experts emphasise that drivers should not ignore night-time safety. IAM RoadSmart director Nicholas Lyes warned: “Reduced visibility and grip in November often leads to accidents. Check headlight aim, clean lenses, and replace any faulty bulbs. Adjust speed and increase stopping distances during darker hours.”

“Headlight glare, particularly from modern LED lights and taller SUVs, is affecting drivers’ vision,” said Denise Voon from The College of Optometrists. She advises to always wear prescribed lenses when driving and consult an optometrist if you experience difficulty seeing at night.

Headlight rules drivers need to be aware of

Staying safe on the road is one thing – but it’s also worth knowing these headlight rules that could save you from some pretty hefty fines.

Using hazard lights while driving – fine up to £1,000

Hazard lights are only meant to be used when you’re stopped, for example if you’ve broken
down or need to warn drivers of a hazard ahead.

Using them while moving – even to say thanks to another driver or flash a warning – is actually against the Highway Code and could land you with a fine of up to £1,000 for driving without due care and attention.

DIY LED headlights – could cause an MOT fail

Thinking of upgrading your lights? Be careful. Fitting LED headlights is tightly regulated, and if they’re not properly aligned or installed, you could fail your MOT. They might also invalidate your insurance if you don’t let your provider know about the change.

Forgetting headlights in bad weather – up to £5,000 fine and penalty points

In fog, heavy rain or snow, you must switch your headlights on when visibility drops below 100m (about the length of a football pitch). Forgetting to do so could be seen as not being in proper control of your vehicle, which carries a fine of up to £5,000 and three-nine penalty points on your licence.

Top tips for drivers this winter

To reduce the effects of headlight glare at night, here are some tips to help you:

  • Keep your windscreen spotless as a clean windscreen (inside and out) makes a huge difference when it comes to cutting down glare from oncoming headlights.
  • Glasses wearers, take note – give your specs a quick clean before setting off. Even tiny smudges can make glare worse at night.
  • Pop in for a routine sight test with your optometrist to make sure your vision, and your glasses or contact lenses, are up to date.
  • Adjust your rear-view mirror to dip slightly if you’re being dazzled by headlights from behind.
  • If a car’s headlights are blinding you, keep your eyes open and glance towards the left-hand kerb or road edge until your vision clears.
  • If you’re dazzled, take it slow. Ease off the accelerator, and if you need to, pull over somewhere safe until your eyes recover.
