What does the yellow dashed line between double arrows indicate?

The yellow dashed line between double arrows is the marking for a tidal flow lane. Tidal phenomenon: Due to the 'tidal phenomenon' in traffic flow, where the morning rush hour sees heavier inbound traffic with lighter outbound flow, while the evening experiences the opposite pattern with heavier outbound traffic, exacerbating congestion. Solution to this situation: To address this, traffic management employs reversible lanes during roadway modifications. Specifically: during morning peak hours when inbound traffic is heavier, the number of inbound lanes is increased while outbound lanes are decreased; conversely, during evening peak hours with heavier outbound flow, outbound lanes are increased and inbound lanes are reduced.
I've seen this type of road marking, and its meaning is quite straightforward—double arrows with a yellow dashed line typically indicate the center dividing line of the road. The yellow dashed portion means drivers can safely cross it for overtaking or lane changes, such as when attempting to pass a slower vehicle if oncoming traffic is light. However, this requires caution, as road conditions can change at any moment. When driving, I always pay extra attention to my surroundings, like checking the rearview mirror to ensure no vehicles are approaching before making a move. Yellow dashed lines are commonly found on highways or suburban national roads, helping to improve traffic efficiency and reduce congestion. These markings are designed based on road width and visibility in open areas to minimize accident risks. I remember learning this during my driver's license test—it reminds us to follow the rules and avoid taking unnecessary risks out of impatience, which could lead to collisions or fines. In short, it's a safety reminder marker.
