When turning left from a three-lane, one-way street, from which lane should you turn?

When turning left from a three-lane, one-way street, the appropriate lane to turn from is the left lane. This is the standard practice because it allows for a smoother and safer turn. When you make a left turn, you want to position your vehicle in the lane that is closest to the left side of the road, which in this case is the left lane. This helps ensure you are not crossing through traffic lanes unnecessarily and reduces the risk of collisions with vehicles that may be moving straight through the intersection or turning right.

Turning from the left lane also provides better visibility for the driver to check for oncoming traffic, pedestrians, and cyclists who may be crossing in front of the vehicle during the turn. It aligns with traffic rules and promotes safer driving practices by keeping turns organized on multi-lane streets.
