1. The green arrow indicates that vehicles in lane 2 may proceed forward.
2. The red X signals that lane 3 must not be used; drivers should change lanes if they are currently in that lane.
3. The solid red circle indicates that lane 4 must stop completely.

In this case, it’s important to recognize that following the signs ensures safety and proper traffic flow. Ignoring any of these signals could lead to accidents or traffic disruptions. Therefore, understanding and adhering to each sign’s instruction is crucial.
