Driving in the dark – dangers and advice to stay safe

Posted on 13th Nov 2025 by CarTakeBack Posted in: In The Know

Recent research by a car insurance company showed that while only a quarter of journeys by car are made in the dark, nearly half of all road accidents happen once the sun has gone down… Whether it’s due to people being more tired, poor car maintenance or reduced visibility, considering the statistics, we all need to be aware of the dangers of driving in the dark.

Our simple and comprehensive checklist will ensure you can keep yourself, your passengers and other road users, safe in the dark!

Tips to prepare for driving in the dark

  • CHECK HEADLIGHTS – One of the most important things to do is to check your headlights – test that they are working correctly and they are properly aligned. If you’re using a car you are unfamiliar with, be sure you know where full beam is and how to switch it on and off quickly.
  • CLEAN WINDOWS – As visibility is the main issue when it comes to night-time driving, it’s essential your windows are clean and clear. A hazy film over your windscreen exacerbates the problem of headlight glare, so whether it’s condensation on the inside, or dirt on the outside make sure all your windows and mirrors are clean and clear before you set off and be sure you know where your heaters are to clear the windscreen once you’re driving.
  • BE RESTED – Don’t set off tired. Being drowsy is always dangerous, but when it’s dark outside it will only amplify your tiredness. If it’s a long journey you should make sure you’re well-rested.
  • STAY SOBER – Never drive under the influence of drugs or drink. Your reaction times and judgement will be affected however little you’ve consumed and the dark just intensifies their affect.
  • CHECK VISION – This may seem a little excessive, but official advice for night-time driving also includes getting regular eye tests. You should have an eye test every two years, more frequently if you have any issues with your vision, especially night blindness. There’s mixed advice about anti-reflective coating on lenses to reduce glare, but it is something opticians may be able to give you trial of, to see if it works for you.

Driving advice for staying safe in the dark

  • TIME TO ADJUST – Give yourself a few minutes to adjust to the darkness before you start your journey. This is particularly helpful if you’ve just left a brightly-lit building.
  • DIM INTERIOR – Reduce the brightness of your car’s interior lights including the dashboard. This small change helps your eyes adjust to the darkness outside of the car and will ensure you aren’t distracted by the interior.
  • SLOW DOWN & KEEP YOUR DISTANCE – As with other challenging road conditions, two driving tips are key – slow down and maintain a greater distance from the vehicle in front of you. With the reduced light affecting your reaction times and judgement, it gives you more time to react to hazards.
  • EFFECTIVE USE OF HEADLIGHTS – Use your own lights effectively – the RAC recommends using your dipped headlights about an hour before sunset and an hour after sunrise to ensure your vehicle is clearly visible.
  • FULL BEAM – While all drivers are advised to use full beam on unlit country roads, you must remain alert and aware of other approaching vehicles. Switch back to your normal headlight setting immediately to avoid dazzling other drivers.
  • AVOID DAZZLE – To avoid being dazzled by headlights yourself, look to and follow the left side edge of the road – ideally the white line – to make sure you maintain a safe position while navigating oncoming traffic and avoiding the direct glare of headlights. If the glare is too bright, or it’s caught you by surprise and you’re temporarily blinded, slow down immediately but without any sudden breaking, so any vehicles behind you also have time to react.
  • TAKE A BREAK – If you start to feel tired during your journey, pull over as soon as it is safe to do so and take a quick break – even a short rest stop can help you to return to the road more alert.
  • STAY VIGILANT – It may sound obvious but being vigilant is essential – make sure you drive to the conditions and take note of your surroundings – you may be driving near a school or in a densely populated residential area. It’s much harder to spot pedestrians, animals and cyclists in the dark and even reflective clothing or small lights can only appear once they are directly in your eye line.

It’s beyond a standard ‘driving tip’ but if you’ve only just qualified, or you’re an experienced driver but you’ve started to feel uncomfortable driving at night, it’s worth investing in extra lessons. Driving instructors often have special rates for pupils to have evening lessons, or you can look into speciality driving courses such as Pass Plus, which will cover night driving as well as other advanced driving elements that will improve your confidence and ability.

It’s a little-known rule in the Highway Code that in stationary queues of traffic, drivers should apply the parking brake and, once the following traffic has stopped, take their foot off the footbrake to deactivate the vehicle brake lights. This is intended to reduce the glare suffered by road users behind them.

What are the dangers of driving in the dark?

VISIBILITY

LESS LIGHT – The darker it is, the harder it is to see! Your eyes take time to adjust and even when there is street lighting, it’s often low and doesn’t provide consistent light. Reduced visibility means less time to read road signs and react to hazards.

DAZZLE – Many people suffer with being dazzled by headlights. Using full beam incorrectly can cause drivers to be momentarily blinded by glare, but many people struggle with normal headlights in the dark. It’s recently been found that women in perimenopause are particularly susceptible to being dazzled by headlights. It can take several seconds for eyes to recover, which is a dangerous amount of time to have your vision compromised.

JUDGEMENT

SPEED & DISTANCE – This is of course related to vision, but the darkness makes it harder to judge speed and distance accurately, whether that’s of other vehicles, cyclists or pedestrians.

REACTION TIMES – Drivers’ reaction times are affected by the darkness and it means your ability to avoid hazards and simply react to the flow of traffic is inhibited.

CHANGING CONDITIONS – The clock change means many drivers forced to tackle rush hour traffic suddenly have to manage congested roads in the dark – the darkness making it harder to judge speed and distance is only made worse by increased traffic.

DRIVERS

TIREDNESS – During Autumn and Winter, darkness doesn’t necessarily mean it’s late, but for very early morning or night time driving at any time of the year, being drowsy is a dangerous condition in which to operate a vehicle. When it’s dark, it will only exacerbate any fatigue and drivers become a danger to themselves and every other road user.

DRUNK DRIVERS – While the overall number of drunk drivers on the road has decreased over the last decade, there are still significantly more drivers over-the-limit at night. Any driver impaired by alcohol or drugs is a significant threat as their co-ordination, judgement and reaction times are affected.

INEXPERIENCE – Newly qualified teen drivers usually have far less experience of driving in the dark and are more likely to be affected by the additional challenges of night time driving – making them more dangerous.

Suffer with glare?

Headlight glare is a growing issue for many drivers. There are several factors that are thought to be contributing to this danger of night-time driving…

  • The increased use of LED headlights means brighter and whiter lights than traditional halogen bulbs, causing a much more ‘dazzling’ effect.
  • While there will undoubtedly be many mis-aligned dipped headlights on the roads at any given time, the increased number of SUVs on the road is also thought to affect lower-vehicle road users.
  • As we age, eyes take longer to recover from glare (from approximately 1 second at age 15 to around 9 seconds at age 65). Due to hormonal changes changing the cornea and the lubrication in your eyes, anyone in perimenopause is also more susceptible to the affects of glare.

The RAC has a super article on headlight glare if you’d like to find out more – their report showed that 25% of people are choosing to drive less due to night time glare of headlights and 5% have stopped driving in the dark all together!

Driving in the Dark – Recommended kit for your car

Hopefully your journey will be trouble free, but in case you have an accident or a breakdown, we recommend having these items accessible in your car:

      1. Torch
      2. Warm clothing
      3. Waterproof coat
      4. Charged mobile phone
      5. Emergency contact details (ICE card)
      6. Ice-scraper

A torch will be useful in most circumstances, particularly a head torch, which will enable you to keep your hands free! Even summer nights can get cold, so warm clothing and a blanket are always a good idea. Plus a waterproof coat in case you have to wait away from your vehicle in the rain. It’s essential your mobile phone is charged before you set off and whether it’s for you or someone else, it’s useful to have an ICE card in your car with details of who you can call in an emergency, including your breakdown cover and insurance company. During winter you should also have an ice-scraper to clear your windows.

If you do break down in the dark, try and find a safe and well-lit place to stop. Wherever you are, leave your hazard warning lights on while you wait for help.

Hopefully our advice for driving in the dark will protect you and other road users. If, sadly, you’ve already had an accident due to the dangers of driving in the dark and your car will cost more to fix than it’s worth, we can still offer you a competitive price for it.
