Under which conditions may you overtake and pass a light-rail vehicle or streetcar on the left side?

• A. All of the above
• B. You are on a one-way street
• C. The tracks are so close to the right side that you cannot pass on the right
• D. A traffic officer directs you to pass on the left

Answer: (A)

You may pass a streetcar on the left when doing so is safe and makes sense for the flow of traffic. The reason all of these conditions fit is that each describes a scenario where passing on the left is the practical and permitted choice: on a one-way street, where traffic moves in the same direction; when the tracks sit so close to the right edge that passing on the right isn’t possible; and when a traffic officer directs you to pass on the left. In each case, you should still check for a safe gap, signal your lane change, and avoid passing if the streetcar is stopping or if there’s a pedestrian or other obstacle in the way.
