On a one-way street, can drivers pass a streetcar on the left?

Answer: A — Yes, under all circumstances

In general, drivers on a one-way street are permitted to pass a streetcar on the left when it is safe to do so. This is because one-way streets allow for the flow of traffic in a single direction, which typically means that passing a streetcar on the left is less likely to interfere with other vehicles. It's crucial for drivers to ensure that it's safe before maneuvering around the streetcar, as considerations like pedestrian crossings, road conditions, and the presence of other vehicles can all play a role in the decision to pass. Moreover, local traffic rules and regulations may further clarify specific situations, and it's vital for drivers to remain aware of their surroundings and proceed with caution. Therefore, under conditions where it's safe and legal to do so, passing a streetcar on the left on a one-way street is appropriate.
