When turning onto a one-way street, drivers should:

  1. Always turn into the right lane.
  2. Always turn into the left lane.
  3. Turn into the lane that will interfere the most with traffic.
  4. Turn into the lane that will interfere the least with traffic. ✓

Answer: D. Turn into the lane that will interfere the least with traffic.

When you turn onto a one-way street, use the lane where you will get in the way of other traffic the least.

Why this is the answer

The Texas handbook's turning chapter says that if you are turning left onto a one-way street, you enter the street in the lane where you disturb other traffic least. It also tells you to watch pavement markings and signs that allow turns from or into more than one lane or give special lane instructions. The handbook repeats this idea when describing how to finish a left turn: enter the lane that causes the least interference. That is why the answer is the least-interference lane, not a fixed right or left lane.

Why the other answers are wrong

Remember it

Think of it as picking the lane that leaves the most room for everyone else, not a lane chosen just because it is on the left or right.
