"During Hurricane Sandy in 2012, a yellow cab driver attempting to enter Manhattan via the bridge says he was stopped and turned back by an officer despite an official police bulletin permitting empty cabs to cross onto the island; he had to return to Brooklyn but quickly picked up a fare. His experience highlights that checkpoints at bridge crossings can be enforced arbitrarily and that written exemptions or notices are not guaranteed to protect drivers during emergencies or curfews." - Kristen Hawley
