Why is there a single yellow line on a one-way street?

There is no single yellow line on a one-way street. A single yellow line is generally used in the middle of narrower roads to separate two lanes. If it is a solid yellow line, vehicles are not allowed to cross the line for U-turns or lane changes. Below is more information about road markings: 1. Single yellow dashed line: A single yellow dashed line indicates that overtaking and U-turns are allowed when there are no oncoming vehicles and it is safe to do so. Vehicles on both sides of the dashed line have the same rights. 2. Double yellow lines: On wider roads, a single yellow line is insufficient for clear distinction, so double yellow lines are used. Double yellow lines are typically applied on wider roads, in the middle of two-way lanes, to separate lanes of opposing directions. 3. Purpose of yellow lines: Yellow lines are used to separate lanes of different directions, usually painted in the center of the road, acting like a divider to separate the road into two directions.

Having driven a taxi in the old city for over two decades, that yellow line on the one-way street may seem redundant, but it serves a crucial purpose. With narrow roads and heavy traffic, the no-overtaking rule enforced by the yellow line prevents vehicles from cutting in and rear-ending others—especially at blind spots around bends, where I've witnessed several minor collisions caused by speeding drivers crossing the line. Moreover, while one-way streets channel traffic in a single direction, the yellow line ensures all vehicles maintain a safe distance in case of jaywalking pedestrians or emergency vehicles moving against the flow. After all these years behind the wheel, I see that yellow line as a silent traffic officer, constantly reminding everyone to follow the rules and avoid accidents born of haste.

I usually enjoy studying traffic regulations. The single yellow line design on one-way streets is a standard requirement aimed at ensuring the stability of one-way traffic flow. Yellow lines typically indicate no lane changes or overtaking, as one-way streets have fewer lanes and limited width to prevent accidents. Just think, without this line, drivers might overtake randomly, causing congestion or even collisions. Traffic laws specify that solid yellow lines represent strict restrictions to maintain overall order. I recommend regularly checking the clarity of road markings, as this directly impacts daily travel safety.

I ride my motorcycle to work every day, passing through several one-way streets, and that yellow line has been a great help. With heavy traffic and crowded roads, the yellow line in the middle means no reckless overtaking, maintaining a steady speed, and smoother driving. Once, I was in a hurry and almost cut in, but thankfully the yellow line reminded me to slow down, and there was no traffic jam behind me. In practice, the yellow line reduces lane-changing frequency and prevents rear-end collisions. Commuters dread being late the most, and the yellow line invisibly ensures the schedule.
