Actually, this is an interesting question, since there are multiple lanes to turn into. Nonetheless, Fairfax Code Section 82-4-55 clearly gives right of way to the blue driver.
In an ideal world, the blue driver SHOULD signal (Section 82-4-2), turn into the curb lane (Section 82-4-48), signal again for 100 feet before he would move into the next lane. That means there SHOULD be no conflict if the red driver would simultaneously turn into his nearest lane. (nonmoron, you should have turned into the nearest lane, and slowly moved over).
In the real world, a noticeable percent of drivers around here don't turn into the nearest lane. We’ve probably all seen turns into a lane three over.
So a reasonable and cautious red driver should wait until the blue driver has completed a turn.
Section 82-4-55. - Right-of-way when vehicle turns to left.
The driver of a vehicle, intending to turn to the left within an intersection or into an alley, private road or driveway shall yield the right-of-way to any vehicle approaching from the opposite direction which is so close as to constitute a hazard, provided, that where there is an automatic signal device governing the flow of traffic at any intersection and allowing turns to the left while all other vehicle traffic is required to stop, any vehicle making such turn shall have the right-of-way over all other vehicles approaching the intersection. ((3-13-63; 1961 Code, § 16-114.)
Section 82-4-2. - Reckless driving; specific instances.
(a) A person shall be guilty of reckless driving who shall:
. . .
(7) Fail to give adequate and timely signals of intention to turn, partly turn, slow down or stop, as required in Sections 82-4-48 through 82-4-52
Section 82-4-48. - Required position and method of turning at intersections; signs.
(a) The driver of a vehicle intending to turn at an intersection or other location on any highway, except as prohibited by the preceding Section or any other provision of this Chapter, shall do as follows:
(1) Right turn. Both the approach for a right turn and a right turn shall be made as close as practicable to the right-hand curb or edge of the roadway.
(2) Left turns on two-way roadways. At any intersection where traffic is permitted to move in both directions on each roadway entering the intersection, an approach for a left turn shall be made in that portion of the right half of the roadway nearest the center line thereof and by passing to the right of such center line where it enters the intersection and after entering the intersection the left turn shall be made so as to leave the intersection to the right of the center line of the roadway being entered. Whenever practicable the left turn shall be made in that portion of the intersection to the left of the center of the intersection.
(3) Left turns on other than two-way roadways. At any intersection where traffic is restricted to one direction on one or more of the roadways, and at any crossover from one roadway of a divided highway to another roadway thereof on which traffic moves in the opposite direction, the driver of a vehicle intending to turn left at any such intersection or crossover shall approach the intersection or crossover in the extreme left-hand lane lawfully available to traffic moving in the direction of travel of such vehicle and after entering the intersection or crossover the left turn shall be made so as to leave the intersection or crossover, as nearly as practicable, in the left-hand lane lawfully available to traffic moving in such direction upon the roadway being entered.
(4) When markers, buttons or signs are placed within or adjacent to intersections and thereby require and direct that a different course from that specified above in this Section be traveled, no driver of a vehicle shall turn a vehicle at an intersection other than as directed and required by such markers, buttons or signs. ((3-13-63; 1961 Code, § 16-107.)
