For clarity, as one comes up behind a cyclist at night on an unlit road, is it a reasonable common sense reading of the HWC that there is a risk of dazzling by using high beam such that one should (or must) always dip?

FWIW I'd use dipped beam as I would when approaching another car in similar circumstances,I may flash the main beam to let them know I'm there and will be overtaking,but depending on the road I may do that to another car too.Once alongside the cyclist or car I may switch on main beam should I need to.

Yes (must). How can you read "You MUST NOT use any lights in a way which would dazzle or cause discomfort to other road users, including pedestrians, cyclists and horse riders" in any other common-sense way?

Are people arguing that it's fine as long as the lights dip each time a cyclist looks backwards? Or that being dazzled is the cyclists' own fault for daring to look backwards like trained to do?

Just to be clear, are you saying main beam from 2-3 miles behind is dazzling?

No, only that main beam is dazzling on such straight roads much further than they provide any "better view". I've not tested the boundary and hope I don't need to.

They are a road user, so you do the same. Dip until past.
A shortcut has to be a challenge, otherwise it would just be the way. No situation is so dire that panic cannot make it worse.

Dip your headlights. And to complete the set: what must you do when approaching a horse rider from behind?

It *is* at the expense of the cyclist.

It's either detrimental to my sight *now* or detrimental to my sight when you pass - I have my own lights, I don't want yours.

I have wing mirror(s) and your lights are absolutely detrimental...

A D/deaf cyclist is arguably *more* likely to have mirrors, besides which I can see your dipped beams quite happily thanks.

I'm interested to understand why this is the case.


Because full beam lights into my mirror into my eyes is damned uncomfortable - whether on a bent or not. The only difference the bent makes is that people who drive *far* too close, or drive tanks with poorly adjusted dipped beams are also a pite.

A while ago in the car,I was in traffic jam in the dark that wasn't going anwhere anytime soon,behind me was a newish,lazer lamp Range Rover.
After about 10 minutes I got out and asked the driver to turn off his headlights as they were burning a hole in the back of my head!
He was oblivious to the problem,even though the inside of my car was light up like a football stadium :? :roll:

I get the same when driving, and I drive a grand scenic, so not exactly a low slung car.

Why did you complain? Didn't you enjoy benefitting from a better view of what's inside and beside your car? ;-)

I am grateful for your emboldened sections, it helped me understand you better. I think I was making a more nuanced point. Allow me to explain (excuse the lack of caps/bold - I'm assuming you won't need the help you offered me).

I note the HWC says "would", not "could". That's an important distinction and to me suggests that a "risk of" dazzle perhaps falls short of that standard. A plain reading would suggest it's hard to dazzle someone facing the other way.

We all, as road users, have some reciprocal responsibilities. I am contending that an offence may not have taken place if in the circumstances someone used main beam, seeing a road user was moving away from them with their back to them. If a walker or cyclist, seeing, as they would, the level of illumination provided by a set of car main beam headlights chose to look at those main beams such that they were dazzled (glancing is of course entirely possible without dazzle, as in Vorpal's "life saver" example), then would that constitute an offence? I think, on balance that it would not.

I have no idea if that's ever been tested, I suspect not, but would one really seek a prosecution in that circumstance? I imagine the conversation might run thus:

"I'd like to report an offence contrary to Rule 114"

Misc back-and-forth clarification...

"So sir, you were cycling in the same direction as the car?"

"Yes"

"The motorist had his main beams on, and you looked back at them and were dazzled?"

"Yes"

"Why?"

"Because I'm trained to"

Add your own ending to suit - mine ends in a vanishingly small chance of any action being taken, yours may not...


Whilst we're on the subject, a horse is a very different proposition to a more rational road user, and indeed, can see rearwards as its eyes are set on the side of its head, so absolutely a dip is required, because a horse would be dazzled.

Because Ibhave to look back to check that your client, and other idiots, aren’t doing anything stupid and risking my life.

Sorry - but you don’t put full beams on behind another car, why would you do it to any other road user?

So you would use your hi beams with other vehicles going the same way? I think not.

3 out of my 4 bicycles have rear facing mirrors ... so how would you determine if the bicycle had one or more rear facing mirror/s? Wait for them to fall off? Your going to have to get very close to see my revision mirror ... by that time I'll probably be blind, stopped and very angry!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I too dislike main beams from behind. I can see nicely with my lights, if they are swamped from behind then there are more shadows and I cannot necessarily see the line through corners. Not usually a real problem, but definitely an irritation. Some years ago I was riding to a country pub down a pitch black and winding lane. A car came from behind and main beams stayed on. When we all arrived at the pub, the passenger commented on how fast I was going; I replied that I would have been faster if the fool driver had been on dipped so that I could see my way around the corners instead of having vison dominated by where his lights were pointing at the time. I think the point was made.

I often find that wind noise in my ears keeps me from hearing motor vehicles very well, anyway. That obviously doesn't apply if I am stopped and waiting, but it certainly can if I am approaching a junction on a down hill or moving quickly to keep up with traffic. The noise doesn't die down sufficiently to hear everything until I slow down quite a bit.

Lastly, there is a damn good reason that motorcyclists call the last look over your should before a turn, the 'lifesaver', and it honestly has prevented me crashing, likely seriously, on at least two occasions when some idiot dangerously overtook me at the last moment.

The land of electric cars..
I thought Norway was the promised land (went there once!) but I just read that some e-car owners claimed compensation cos their vehicles did not have 700kw as claimed, only 470kw :(
70kw is plenty

Don't the tyres make some noise?
