Whose fault? Cars coming in opposite directions make turns onto same st, one hits other in left most lane.?

The car that turned right into the left lane is at fault

A complicated question with a very simple answer. Common law, which applies to all states as far as I know, is that you must finish your turn in the lane you began your turn in. If you need to switch lanes, that is done later, not at the same time as the turn. So a vehicle turning left must end up in the left land after the turn, not the right lane. If he needs to turn right in the next block he must change lanes AFTER the turn and AFTER making sure the lane is clear. Likewise the car turning right must stay in the right lane until the turn is finished, not turn immediately into the left lane. The car turning right and changing lanes is at fault.

I would guess that the person that turned left onto the street would be considered at fault. They did not have the right of way, and they had more time to adjust for the car turning as they had better visability. I think the claims adjustor will do something similar to an 80/20. 80% at fault for the left turn driver, 20% for the right turn driver for making an illegal lane change.

All insurance companies say to deny responsibility until it is determined.

I'm reasonably certain it's universal practice in the US that when performing any turn, it's proper to enter into the closest lane, never crossing over into the next lane until you've safely completed the turn. At that time, after checking to make sure the lane is clear, you can put on your turn signal and then move into the next lane. That would translate into the right most lane when turning right, and the left most lane when turning left.

When you make a turn, there is no (general) requirement to turn into any particular lane. The exception is if you are using a filter lane or similar that guides you into one specific lane of the road you are entering. If you did not cross a solid white line when making teh turn then you were within the law.

When you make a left turn you must yield to oncoming traffic. That includes cars that are making a right turn into the road you wish to enter.

Therefore the car making a left turn is at fault. It failed to yield.

Assuming that there are two lanes to turn in to, each vehicle MUST turn into the proper lane. The vehicle truning right must turn into the rightmost lane and the one turning left must turn into the leftmost lane.

The usual rule of yielding to the right (the car turning right in this case) does not apply because there are two lanes to turn in to.

So, in the scenario presented, the vehicle turning righ would have been at-fault had there been an accident. The vehicle turning right would have been cited for "failure to maintain proper lane direction" if it was witnessed by a cop.

The car turning left is at fault. The car turning right can go into either lane (if there is only one right turn lane.)

The car making a right hand turn is not at fault. He has the right of way and it doesnt matter that he made a mistake by getting into the left lane. The driver making a left turn shouldve been able to maintain control of his car and shouldve been driving defensively. You have to predict that people are going to do stupid things with their cars and drive accordingly.

The car that turned right into the left lane its their fault

The car making the left turn into the left most lane has the right-of-way. The car turning right has to yield.
