To think that you should always use your headlights when driving in the dark?

Now that it's getting darker much earlier in the afternoons, I've started seeing quite a sizeable minority of people each day driving either only with sidelights or with no lights at all when it's already properly fully dark - dark enough so that (thankfully) virtually every other driver does have their lights on. I don't know if it's just in my area or if people are doing it everywhere?

Am I missing something important here, or do they just have a death wish? How difficult is it to turn a knob and put your lights on? Do some people genuinely believe that headlights are strictly only for night time - and if it's 3:30pm, you don't turn your lights on because it's still only the afternoon, even though it's far too dark to see properly or be safely seen without them?

AIBU to think that it should be 3 or even 6 points on your licence for dangerous driving, unless your lights have just that moment failed on you and now don't actually work? Just why?

I find it weird that you're allowed to drive without lights on in the uk at all, in my country headlights have to be used regardless of light conditions so you don't just forget to switch them on when its dark as you switch them on as soon as you start the car. Much more visible, much safer.

It’s very rare that people drive around in the dusk/ dark without headlights, I think you’re exaggerating a bit. It would be quite an old car that necessitates tuning them on too.

as others said, they forgot. Flash them and they’ll be reminded

you don’t seriously think they’re just refusing to put their lights on for fun do you?

SheinIsShite · 06/12/2025 12:26

My car has an auto function and the lights come on automatically when the light is a certain level.

DH's car doesn't and when you are driving on well-lit roads in a city and can easily see where you're going, it's easy to forget.

AntisocialMedium · 06/12/2025 12:23

@NellieJean , There's a large town centre supermarket near me and the car park is brightly lit. The road outside is well lit. I see cars without lights quite often. It's a simple mistake not dangerous driving and the AIBU was AIBU to think that it should be 3 or even 6 points on your licence for dangerous driving for not having the lights on.

The OP never forgets anything, apparently, so is merely judging those who do.

I'm not sure who ever told you that about me - they were most certainly wrong!

But there's forgetting - which could indeed include pulling away and then realising that you've forgotten to put your seat belt or your lights and quickly remedying it, which many of us will almost certainly have done when our minds are elsewhere - and merrily driving along for miles and it never crossing your mind to even double-check that your lights are on when it's pitch dark. If your mind is too busy to even remember that you need your headlights on when the road is very dark, I would suggest that you aren't in a frame of mind and therefore are unfit to be driving at all.

Of course we all forget things, but most of these things only impact on ourselves. If you forget to bring an umbrella and you get soaked, it doesn't affect anybody else and it doesn't really matter unduly. If you forget to put the milk back in the fridge and find it on the side the next morning, you have to go without your cornflakes and it's no great loss to anybody. On the other hand, if a pedestrian is crossing the road in the dark when they check and can see no oncoming traffic, and a completely unlit car smashes into them at 30mph... that's possibly a rather more important reason not to forget something.

Only on mn could several people argue about putting their lights on when it’s dark! They could argue in an empty room I suspect.

well they obviously can see well enough, that's the whole point!
I'm sure if they were driving in pitch dark on a B road they soon would realise, but between all the street lights, stars/light pollution and other people's car lights it's rarely that dark on most roads in the UK at mid evening.

I have my lights come on automatically now but I definitely forgot once or twice in previous cars that didn't have that option. It's not some sort of grand conspiracy, or strength of feeling about the exact time of day, it's just human error.

You seem to be unnecessarily pedantic. Nobody is going to argue that it's not safer to have lights on once it gets dark, but at the end of the day people do forget things! There's not really more anyone can say to that, so I don't really understand what you want from this thread.

It's not at all comparable to having multiple pints because that's an active choice you make, not slightly misjudging driving conditions and not realising you haven't turned your lights on until 3:33 when it was probably dark enough to do so at 3:21.

My point is that, as a driver, you simply cannot rely on other drivers using their headlights or on councils turning on streetlights and keeping them in good repair. I'm surprised that dangerous driving doesn't concern you too.

I'm not saying that it's a grand conspiracy, but I was wondering what goes through people's minds to fail at such a basic essential of driving. I know people can make human errors, but I'm just shocked at how often I see this recently.

Somebody upthread did specifically assert their belief that there is no need to use headlights at night if there are streetlights - supposedly backed up by the Highway Code!!!

I've addressed the analogy with drinking several pints twice above. It was about people 'forgetting' the absolute basics of driving before being in charge of a potential death machine. I've also repeatedly said that I'm talking about when it's properly dark and dismal and not just when dusk is gradually starting to draw in.

From this thread, I wanted to ask people's opinions and thoughts as to why so many people seem to do this and whether it was happening a lot elsewhere or just a concerning peculiarity in my own town. It's an online chat forum, where people discuss all manner of topics that cover the entire gamut of human interest - whether that be the war in Gaza, what people's favourite dishes are from the Chinese takeaway or anything in between. It isn't an emergency COBRA meeting or a UN summit and nobody is forced in any way to participate in any thread!

It's very MN how some people are denying that other people's experiences of weather in different parts of the country and on different days could possibly differ from their own!

The weather doesn't know or care one bit that 'but it's too early to be dark and gloomy yet'!!

And if somebody 'forgot' that they'd had several pints before driving?

How can you forget that you're supposed to be able to see the road ahead of you, or indeed your dashboard?

But isn't the point of automatic lights that it doesn't matter if you forget - because the car will already have turned them on itself?!

Most automatic car safety features tend to err on the side of caution, sometimes to the point of annoyance - if anything, you'd expect them to come on when it's still quite light; not wait until it's really, really dark.

Or you can switch them off as in from Auto to always off or always on. This happened to me recently. I have my headlights always on auto, left the car to be serviced and they switched them to off. I drove out of the garage about 5pm and it was just starting to get dark. Also driving on well lit roads with lots of traffic so not immediately obvious. Took me a good ten mins to realise and I’m sure lots of people who passed my car thought I was an idiot. There were the daylight running and spots that would have been on so not in complete darkness

One issue is if your car is in the garage for anything they switch the auto lights off to avoid flattening the battery.
I also imagine working on an engine with those lights in your face would be annoying.

Over many years I have flashed many cars with no headlights, inc the police, I never noticed it was a police car until the lights and the light on top went on (back in the days when police cars were white with a strip on the side)

But surely people think about this when they collect their cars after an MoT or repair? If the mechanic is significantly taller or shorter than you are, they've probably moved the seat back or forward from where it suits you. They may have left a plastic seat protector on, which is clearly not intended to stay on there after you've collected it; they might even have turned the radio station over from Classic FM to Kerrang whilst working on it!

Yes, they've repaired and made your car safe to drive, but that doesn't mean that you don't have to routinely check a few very basic settings and adjust them if necessary when you get it back. They're a mechanic; not your mum.

Needspaceforlego · 06/12/2025 11:20

Nobody drives without them on purpose. Its either jumping between different cars, or cars being in the garage, etc.

Nobody is deliberately putting themselves at risk of not being seen

Boing98 · 06/12/2025 11:01

It says seriously reduced. On a dry, clear night, just being dark would not count as seriously reduced.

Eh? Being dark doesn't equate to seriously reduced visibility?!

I assume it's either referring to full beam (as opposed to everyday dipped beam) or maybe when the street lights have only just come on early - as they tend to be set to come on half an hour or so before the dark properly kicks in.

That said, street lights are set based on the time and season, so they aren't on when the weather is very gloomy and visibility is hugely reduced outside of those times - plus they may well be broken!

Why are people looking for excuses to justify not putting their lights on in the dark/gloomy weather because of a technicality? There seems to be a fear of ever being any safer than 'maybe just about safe-ish enough'! Headlight bulbs usually last for years before they have to be replaced, and even then, they're hardly expensive.

Unless you’re Aberdeen or north, at 3.30pm it’s not dark, dingy especially if weather is cloudy but not dark. Sunset is 4.03pm today where I am, you certainly don’t need headlights until 4.20 or so, 15 minutes after sunset for darkness but in foul weather you need them anyway (it’s thankfully drying up finally outside)

Sunset is 3.45 today, in Glasgow.

Well, the highway code also says:

You should also

  • use dipped headlights, or dim-dip if fitted, at night in built-up areas and in dull daytime weather, to ensure that you can be seen

So you should have them on regardless.

Politicians247UnderwearExtinguishingService · 06/12/2025 11:01

VickyEadieofThigh · 06/12/2025 10:51

Indeed. My previous car had automatic headlights, but my current one does not adjust when it gets darker. At first, I would find myself driving on the 'daylight' setting.

Nobody does it on purpose, OP.

I would counter that by saying that you need to purposely make sure that you have adequate lights as a basic routine when driving. Headlights on a car when driving in the dark or otherwise poor visibility aren't a 'nice to have' optional extra - they're absolutely essential.

Sometimes, omission can be just as much a fault - and a danger - as commission.

Because while it says you don't HAVE to use them when there are street lights, it also says you MUST use them when visibility is reduced, which is often the case even with street lights.

What? Do you mean you don't need to use full beam (undipped) head lights when there's street lighting - in which case I would agree with you?

Why do some people have such an aversion to basic safety, when it literally takes two or three clicks of a knob? Are they trying to get a few more weeks' life out of a couple of already long-lasting £10 bulbs - like the man on the recent thread about tightwads who would cut matches lengthwise into four, to save himself a few pence?!

Lighting requirements (113 to 116)
113
You MUST
ensure all sidelights and rear registration plate lights are lit between sunset and sunrise

use headlights at night, except on a road which has lit street lighting. These roads are generally restricted to a speed limit of 30 mph (48 km/h), or 20mph (32km/h) in Wales, unless otherwise specified

use headlights when visibility is seriously reduced (see Rule 226).

Driving in adverse weather conditions - Overview (226)

You MUST use headlights when visibility is seriously reduced, generally when you cannot see for more than 100 metres (328 feet)
