Final answer:
The center, shared lane with a solid and dashed yellow line on New Mexico roadways is a shared left turn lane for both directions, not for carpool, emergency vehicles, or VIPs with special permits.
Step-by-step explanation:
The center, shared lane on many New Mexico roadways, denoted by a solid and dashed yellow line, is used as a shared left turn lane for vehicles traveling in both directions. This type of lane allows drivers from either direction to use the lane for making left turns at intersections, driveways, or when permitted, onto other roads. Therefore, the correct answer is that the center lane is a shared, left turn lane for both directions of travel.
The presence of a solid and dashed yellow line indicates that it is not designated for carpool only, for emergency vehicles only, nor is it reserved for VIP operators with a special permit and sticker. Understanding the correct use of this lane is important for safe driving and compliance with traffic laws.
