Overtaking Cars - Legal Status

There is some case law on this area and it is pretty common sense, thankfully.

If you are filtering on the wrong side of the road, you are putting yourself in a potentially hazardous position, so you need to take extra care. Therefore, if a cyclist is going too fast to avoid a car pulling out from a side road, through the stationary traffic, then the cyclist would usually be 50% liable for the accident.

The driver is also performing a potentially hazardous manoeuvre, as they cant see the bike filtering on the outside of the stationary traffic, so if they were not pulling out cautiously then they would usually be 50% liable for the accident as well.

That's makes sense Oliver.
Doesn't the dotted line down the middle of roads have the same legal status as give way lines? ie it is alright to cross them but you don't have priority so oncoming drivers have right of way.

Both the overtaker and the driver pushing through the traffic jam have equal responsibility so need to negotiate. In situations where negotiations need to happen people need to move at a speed where this can happen... slowly
