Which violation describes moving from one lane to another in an unsafe manner?

• A. Turn on red not permitted
• B. Fail to yield at yield sign
• C. Passed red light
• D. Moved from lane unsafely

Answer: (D)

Unsafe lane changes happen when you move from one lane to another without making sure it’s safe. The key habit to prevent this is signaling, checking mirrors and your blind spots, and ensuring there’s enough space and time before you merge. If you change lanes and another driver has to brake, swerve, or slow suddenly, you’ve done it unsafely. The other listed violations involve different situations—turning on red when not allowed, failing to yield at a yield sign, and running a red light—so they don’t describe the act of changing lanes unsafely.
