"when the light turns green, it becomes almost impossible for the driver to turn right, because of the bikes already there, as well as the additional bikes coming from behind, completely ignoring the right blinker on the car." Isn't that how it should be ? I'm not in DK, but in LV traffic laws in such a situation they should ignore the blinker, the driver must wait and turn right only after everyone going straight e.…

No, the law clearly says that you can never overtake a vehicle on the right - and it applies to cyclist the same as to everyone else, even if the vehicle wasn't turning right it's illegal for the cyclist to overtake it on the wrong side.

Do I misunderstand your traffic laws (taken from https://www.retsinformation.dk/forms/r0710.aspx?id=158005) pt. 21 about overtaking, which says "... Cyklist og fører af lille knallert kan overhale køretøjer af andre arter til højre." which seems to translate that it does not apply to cyclists and they can overtake on the right?

And 26.6 "...Ved svingning til højre må den kørende ikke være til ulempe for cyklister og knallertkørere, der kører lige ud. ..." saying that vehicles turning right must yield to cyclists going straight?

I feel a lot of commenters are simply focusing on what signs can do or what sort of junction to build, rather than focus on the fact that on high speed primary country roads, bicycles shouldn't be sharing the road with the cars. In Denmark, a lot of high speed roads (excluding motorways, of course) out in the country have separate dual-way bicycle lanes near it but not attached to it. (Example: https://i.imgur.com/dS…

Can you do 30-40 km/h on those bicycle roads or is there slow traffic such as 10-20 km/h bicycles and runners? In the latter case fast bicycles will stay on the main road no matter what. In my experience I also have much better visibility at junctions on the main road instead of on bicycle lanes that are closer to walls and hedges and have 3 or 4 meters less of buffer between me and incoming cars from the right. I'm…

> I also have much better visibility at junctions on the main road instead of on bicycle lanes that are closer to walls and hedges and have 3 or 4 meters less of buffer between me and incoming cars from the right. I'm also less visible to them.

More anecdata: I take the bike when I can, and I have had motorists run into me a few times.

Every single time has been on dedicated bike roads.

Don't get me wrong -- I have had many, many more near misses on regular roads, but regular roads are built in ways which make it easy to convert impending collisions into near misses. Bike roads tend to not have those margins.

Before dedicated bike roads can be considered a solution, they must be built in ways which make me feel safer when I choose them.

No, bicycles and small scooters (limited to 30kph, allowed on bike lanes) are allowed to overtake on the right.

Which is precisely why right-turning drivers should leave no gap between the car and the curb, to claim their space, as it were.

Yes, the car must yield, which is why the best approach is to wait for a gap in the flow of cyclists, and then go all the way to the curb, leaving no gap.

Of course, bicyclists will just jump the curb, ride on the sidewalk or overtake on the left, because everyone wants to be in front.

Unfortunately, the cycling organizations don't really like to admit that most right turn accidents happen because cyclists don't seem to understand that motor vehicles have blind spots, and big motor vehicles have bigger blind spots. As someone who regularly drives, bikes, walks and uses public transport in Copenhagen, it is blatantly obvious that people just don't know how to handle right turns involving both cars a…

This could not apply to Copenhagen and Denmark but I guess that in most other countries cyclists are also car drivers and spend more time in their car than on their bicycle. However there are many car drivers that don't have a bicycle or seldom use it, maybe because they are scared by cars. If the driver is not a cyclist it's difficult to understand what's going on. I suggest that to get a license one should also get…

There is definitely an issue with crossing over to overtake on the left, which is why the best thing to do is actually to stay behind the car, but leave some distance to the curb, to claim your position in the lane.

That way, there will be no cyclists blocking the car from turning safely, and the driver will only have to yield to pedestrians in the crossing. To put it bluntly, it's because they're idiots.

Wow, after all these years I finally learned the name of this phenomenon, constant bearing decreasing range. I recall a scene in the movie Sin City where two cars crash and the camera was moving in CBDR to the perpendicular car as it zoomed into the impact site. I thought it was a cool shot. Also I’ve almost hit pedestrians several times when they were obscured by my A pillar. Sometimes I wonder if I would have actua…

The Sidewinder missile is based on this phenomena. Early guided missiles attempted to home in directly on the target, bringing the bearing from centerline to zero, but they could never make the math work out right in the guidance system. The Sidewinder was the first to realize that the missile is closing in on the aircraft at some speed, and so really the angle it makes with the plane should be constant , not zero. T…

Sidewinder was certainly not the first AAM to employ CBDR / collision-course guidance.

It was experimented since the late 1940s and early variants of the US Navy's radar-guided Sparrow employed it from 1953 as did the USAF's Hughes Falcon c. 1955. In fact Hughes engineers provided input on the technique to the China Lake Sidewinder team!

> The main type of accident involving cyclists in Denmark are so called 'right turn accidents' It's the same in London, a city with notoriously poor cycling infrastructure and narrow streets due to long history. Ok, it's the "left turn" mirror image version due to driving on the left not right side of the road, but otherwise the same.

It’s not helped by cyclists habit of going straight on from a left turn lane.

That is one of the things that annoy me most about new bike lanes. Why do they put them on the left side of left turn lanes!?? Look, we have had lanes for traffic like a century now. It shouldn't be hard. They just have ti do what they always did!

(Also the stupid unsafe cycling advice of staying to the left. Take the lane and take the correct lane, please.)

That is both legal and necessary to do

I absolutely disagree. If I, as a driver, see someone in a left-only lane, it should ba absolutely safe for me to assume that they are indeed turning left - so I can safely pull out at the junction. Obviously it leads to accidents if the person then goes straight and runs into me. Being in a left-only lane is the same as indicating a turn.

If I as a pedestrian/motorcyclist/car-driver assume such things, eg that people not using turn indicators aren't turning then I'd have an accident at least once a day.

Making a couple of second allowance to protect the lives of other road users seems reasonable to me.

That said I don't live in an area with high cycle use - in the small UK city I'm in you're more likely to be stopping to avoid a drunk or a teenage boy doing wheelies.

>and runs into me //

Cleverly worded, but if you use your mirrors properly ... what's that phrase "hell is other road-users"?

Yes, you can do 30-40 on the bicycle paths, and bicycle paths are not used by pedestrians.
