Dinosaur Roadblock

Listen up, buttercup. Dinosaurs can't just stroll across the road because, and this is a big one, they're super dead. Like, extinct. You know, gone-zo. No more dino-sightings except in museums. You probably think dinosaurs still exist, and you'd probably try to pet one even if they were still alive. Face it, you ain't the sharpest tool in the shed.
