Correct Answer: B. A zone where it is illegal and unsafe to cross the pavement markings
Striped pavement buffers flank HOV lanes to mark designated entry/exit zones. Crossing the striped buffer between entry points is illegal and high-risk — HOV traffic often moves faster than adjacent lanes, so abrupt lane changes cause high-speed collisions.
