Help appreciated guys, Person A is turning left out of a car park, person B in incoming traffic yealds and 'flashes' person A to allow them out, person C overtakes person B as the road turns into two lanes about 50 yards further on at the traffic lights and collides with person A.... Who is at fault here?

Flashing headlights mean nothing more than "I am here"

Forget 50/50, liability will be split 3 ways but in varying degrees.

Driver A acted on the signal of another road user and failed to check that it was safe.

Driver B gave a wholly inappropriate signal upon which another driver acted.

Driver C overtook when it was clearly unsafe to do so.

Driver C will be held primarily liable, but contributory negligence will/could be filed against drivers A and B.

All depends on how good your insurers or legal representatives are, but I have dealt with a few of these types of cases.

I believe that insurance may say 50-50 however, strictly, person A is at fault

If pulling out from a junction you have to give way to traffic on the road you're turning into from both directions, regardless of the direction of travel in a given lane - i.e. including anyone in the "wrong" lane making an overtake

Being flashed out doesn't change anything, it's on driver A to pull out when it's safe

Person C is acting in an inadvisable way by overtaking at a junction, and person B too - technically you shouldn't flash people out, but I think the majority of blame would fall on person A

This may be wrong and someone may correct me!!

That does make sense to me @TC1474

Just I remember seeing a similar scenario, simpler, as it didn't involve a 3rd road user flashing, it was someone who only checked to their right when turning left and had a head-on with a driver who was mid-overtake

It was commented that the overtaker should certainly have thought before overtaking near a junction but liability went with the car who pulled out into the main road

I guess, like you say, it depends on who has the best insurers/lawyers?
