Why is a weave lane on a freeway considered very dangerous?

• A. There are both entrance and exit lanes, so cars cross paths.
• B. Weave lanes have reduced visibility.
• C. The speed limit is higher in weave lanes.
• D. Weave lanes are only for trucks.

Answer: (A)

The key idea is that a weave lane creates cross-traffic conflicts because vehicles entering from an on-ramp and those exiting to a off-ramp are all using the same area to merge with and diverge from the main roadway. This means cars are trying to merge into the flow while others are moving out of it, all within a short distance and often at different speeds. Those simultaneous merging and exiting movements create frequent, unpredictable interactions and increase the chance of collisions. Quick decisions, changing speeds, and gaps that can be hard to judge make weaving particularly risky.

Reasons other options don’t fit: visibility isn’t the defining danger of weave lanes, speed limits in weave areas aren’t inherently higher, and weave lanes aren’t exclusively for trucks.
