You are driving on a one-way street. You may turn left onto another one-way street only if:
- sign permits the turn.
- Traffic on the street moves to the right.
- Traffic on the street moves to the left. ✓
Answer: C. Traffic on the street moves to the left.
You may turn left from a one-way street onto another one-way street when traffic on that street moves to the left.
Why this is the answer
The handbook describes a left turn from a one-way street onto another one-way street as starting in the far-left lane and ending in an open lane. For that turn to work, the other one-way street's traffic must be flowing in the direction you will enter. From your approach, that flow is to the left. If it moved to the right, your left turn would put you opposite the way that street is set up to travel. The handbook also says you need no sign permitting the turn; you just need no sign prohibiting it.
Why the other answers are wrong
- A. sign permits the turn. — A sign does not have to permit the turn; the handbook says to check that no sign prohibits it, including when turning left against a red light from one one-way street to another.
- B. Traffic on the street moves to the right. — If traffic on the other street moves to the right, a left turn would point you against that one-way flow, so that is not the street you may enter by turning left.
Remember it
Check which way the other one-way street flows: a left turn joins traffic moving left from your approach.
