Positioning to ride to B,
if there's already a car or two occupying B and the line up with right hand signals on before you reach the intersection, and you are filtering up on the line with more space on the other side of the stripe,
"A" IS the most appropriate, most expeditious positioning.
Using a quick directional hand signal to quell any uncertainty as the cross signal turns yellow - you are at the head of the line, moving straight as the motorist lineup turns right.
if a semi truck was in both lanes, prepping up to turn left, or right, I'd be in different road positions at the intersection. if the semi was turning left or the lead motorist in the straight/right lane was signalling they actually wanted to be turning left, I'm in position "C."
Position "D" is often best when a semi truck is turning right. STAY BEHIND THE TRUCK.
D is commonly also the default 'rolling' position as traffic starts up while you are riding up on traffic to a congested intersection...... positioning not directly beside any car, behind one and in front of another, not able to get to position "B" before reaching the intersection.
Lane positioning is VERY traffic dependant. Use of A,B,C, or D are all best.
