What can a driver do from a shared left turn lane?

A shared left turn lane is specifically designed to allow vehicles traveling in opposite directions to make left turns safely. Drivers can use this lane to prepare for a left turn onto or off of a multi-lane road. This makes the environment safer by providing a designated area for these maneuvers, which might otherwise block traffic in regular lanes.

The other options do not align with the purpose and regulations surrounding shared left turn lanes. Making a U-turn is generally not permitted in these lanes; they are intended for left turns only. Changing lanes without signaling is unsafe and illegal, as it does not provide other drivers with the necessary notice of your intentions. Parking temporarily in a left turn lane is also prohibited, as it would obstruct the flow of traffic and defeat the purpose of having a dedicated turn lane.
