What marks the buffer zone to keep cars apart and prevent a crash?

• A. Two Sets of Double Solid Yellow Lines
• B. Diagonal White Stripes
• C. Dashed White Lines
• D. Solid White Lines

Answer: (A)

Keeping cars in their own lanes and preventing drivers from crossing into oncoming traffic creates a safety buffer between opposing directions. A pair of solid yellow lines on the road means no passing in either direction, so vehicles stay in their lanes and can’t enter the opposing lane to pass. That separation is what reduces head-on crash risk, especially where visibility or road conditions are tricky. Diagonal white stripes mark areas not meant for driving, such as shoulder or gore zones, and don’t create a passing buffer. Dashed white lines indicate you may pass or change lanes when it’s safe. Solid white lines show lane boundaries or road edges and generally discourage crossing, but they don’t establish the no-passing buffer between opposing traffic.
