500
These center lanes are reserved for making left turns (or U-turns when they are permitted),
but can be used by vehicles traveling in both directions. On the pavement, left-turn arrows
for traffic in one direction alternate with left-turn arrows for traffic coming from the other
direction. These lanes are marked on each side by solid yellow and dashed yellow lines. In
some areas, the shared center lane becomes a “reversible lane” during rush hours. Be sure
you can enter the lane and that it is safe before you do so.
