Can you change lanes while in an intersection?

1. Only if you're turning
2. No ✓
3. Only when there's no oncoming traffic
4. Yes

Answer: B. No

No, you may not change lanes while you are in an intersection, and you should not do it on the approach either.

Why this is the answer

The commercial driving guide tells drivers not to change lanes, pass or overtake as they approach or travel through an intersection. It also says that if you are in a designated lane marked by arrows, you may not move into or out of that lane while inside an intersection. The reason given for keeping lane changes to a minimum is that frequent lane changes raise the risk of a collision. The guide's approach is to pick your lane early and stay in it through the intersection.

Why the other answers are wrong

• A. Only if you're turning — Being in a turning situation does not create an exception, because the guide says to get into the proper lane well before the intersection and signal, not to switch lanes inside it.
• C. Only when there's no oncoming traffic — Clear oncoming traffic is not a condition the guide allows, since it rules out lane changes on the approach and through the intersection without any traffic exception.
• D. Yes — A plain yes contradicts the guide, which says not to change lanes as you approach or go through an intersection.

Remember it

Pick your lane before you reach the corner, then hold it until you are clear of the intersection.
