Final answer:
The best travel lane depends on the driver's intended actions and the conditions of the road.
Step-by-step explanation:
When driving on a multilane city street, the best travel lane depends on your intended actions. The left lane, also known as the passing lane or fast lane, is typically used for passing slower vehicles or when you are driving at a faster speed. The right lane, also known as the slow lane or exit lane, is used for slower speeds and exiting the roadway. The middle lane is often considered the safest lane because it allows for better visibility and has less merging traffic. However, it's important to always follow local traffic laws and use your judgment when selecting a travel lane.
