Which statement best explains the hazard of weave lanes on a freeway?

• A. There are entrance and exit lanes, so cars cross paths.
• B. It is the fastest lane.
• C. It is reserved for trucks.
• D. It is on and off the ramp only.

Answer: (A)

Weave lanes create risk because vehicles entering the freeway to merge and those leaving to exit must cross paths with through traffic in a short stretch. That merging and diverging happens in the same area, so cars are changing speeds and lanes while others are already traveling in the main lanes, increasing the chance of side-swipe or cutting-in collisions. The best way to describe the hazard is that there are entrance and exit lanes, so cars cross paths.

The other descriptions don’t capture the key danger: simply being the fastest lane isn’t the core hazard, and weave areas aren’t about a truck-only lane. Also, the hazard isn’t limited to ramps; weaving involves merging and diverging within a short distance on the freeway.
