No, pregnant people are strictly advised against riding DINOSAUR at Disney's Animal Kingdom. Disney's official health and safety advisories classify DINOSAUR as a "high-intensity" attraction that features sudden drops, sharp turns, and, most importantly, extremely turbulent jarring motions. The ride uses an Enhanced Motion Vehicle (EMV) that mimics the feeling of traveling over rough, rocky terrain and fleeing from large predators; the resulting vigorous shaking and sudden lurching pose a risk of placental abruption or other complications. Every Disney attraction has a specific "red triangle" warning sign at the entrance for expectant mothers; DINOSAUR is prominently marked with this warning. While the ride does not have high speeds or loops, the sheer physical intensity of the vehicle's "off-road" movement makes it one of the most physically demanding rides in the park, and it is safest to skip this one in favor of gentler experiences like Kilimanjaro Safaris or Na'vi River Journey.
