RVLR. It says they must switch on when the engine is on, must be on when sidelights are either on or off, and must switch off when the headlamps are on.

I don't see how that can be interpreted in any other way.

Can you think of an example of an operational state of the 'other' lamps, which would result in the DRLs being off ? I can't.

No, they have to be operational.
24. They must be operational

Operational doesn't nessecarily mean on, just be operational - ie can be turned on if required.With the way you say they must be on because the must function in a certain way is on you could say that the regs say fog lamps must not be used if visibility is better than 100 meters so MUST be used if visibility is less than 100 meters, and like wise this is not the case, although advisable.Like I say, don't get me wrong, I think it should become legal requirement for them to have to be operational, but unfortunatly atm its not the case, what you've quoted confirms it.

Regarding rear fogs. RVLR prohibits their use:

Part III, s.27, 1.3 (b)Used so as to be lit at any time other than in conditions of seriously reduced visibility.

I disagree with your interpretation of 'operational'. RVLR prescribes the manner in which they must operate.

The mind boggles, why would you actively try and make yourself less visible :confused:

Seems to go on about how they must operate in conjunction with other lights, but not that they MUST be used when no other lights are illuminated.Although would be a nice if you were right as those who switch them off obviously have no common sense imo - why try and make yourself less visible, regardless if you think they're worth having or not.

Sorry mate i do not agree with you. I do not believe that using these daylights on days such as today will increase visibility to reduce the risk of an accident.

It depends on where you are driving in a built up area perhaps not driving on a motorway probably not. Driving on roads such as country a roads and b/c with patches of tree cover then they are probably beneficial. As been from fully sunny to 'dark' it takes time for your eyes to adjust.... Then take into account those dank winter days again probably for the better been on. Or dawn /dusk when the sun is low in the sky dazzling drivers that extra bit of light might make you easier to see

But each to their own. :-D. After all people drive into the back of the great big impact protection vehicles they use on the motorway with the 20 ft keep right arrow high intensity strobes and led beacons at the rate of about one every 2 weeks (iirc) the other year according to highways agency statistics

Not sure what sort of day you have ATM, but I know ATM here they're being beneficial.

Sooner they can't be switched off the better, if only so those who don't now how to correctly use their vehicles light are illuminated in rain etc.

See your point on that issue, i too have experienced these people who like to drive without lights in torrential rain and dark clouds.
But even then isn't it only the front lights are on and not the rear which would mean that these people still won,t get seen.

Anyway i certainly have learnt something since my first question on how my driving lights came on and found some interesting reading and opinions.
Long live the Forum

You can't help the real Muppets short of taking their licence off them with the lights on at the front and not the back think of the closing speed on a a road been of 120 mph ish head on..... If your closing on a vehicle doing 40 your only closing at 20 mph :)

Long story short, the naysayers are correct, and I'm gong to go have a big slice of humble pie. I may even have several infact
yummy.gif


Here's the deal. The IVA Inspection manual (Individual vehicle approval) for passenger cars, is not the MOT manual.... and the MOT manual has absolutely no requirement for these lights, unless they are of the dim-dip variety (i.e. it's the same bulb as headlights/sidelights, operated at a different intensity)

So, the E.U. come up with this DRL rule, we as a member are expected to comply with it... so we introduce an amendment to the IVA (i.e. the type approval) for cars to say they must be fitted, operational, yadda yadda - we even amend RVLR (why ?) to state how they must operate, then in the MOT inspection manual we make them optional :confused:

No wonder motorists are getting f****ed every, single, day !

Anyways, links and text:

Inspection Manual

Position Lamps

"Additional or optional lamps are not included in the inspection."

@ Andy haha, ya it was Tasty.

@ MEP - I can admit when i'm wrong, once I run out of arguments :D

It is a tad confusing though, we're told left right and centre we need to comply with XYZ, then when you REALLY look into it, the government have made a half arsed job of implementing it and actually it's all just drivel and nonsense !

So bad that even the police can't work it out..... Ok it's a mundane set of lights on a car...... Look into cycle light law..... At what time and when is a flashing bike light permitted? You go to a bike shop and try to buy a legal set.... Trust me it's nearly impossible!

Then wait till they get confronted with something far more involved like fire arms law and even with the best intentions some officers make themselves look a total arse when confront of someone who had done their homework and refuses to back down as they know more than them dispute them throwing the threat of asbo's and arrest into the mix ;)

It's got to the point to know the law inside out relating to any hobbies you have or activities you partake in!
