Roller coasters and other amusement rides spun, dropped and catapulted more than 10,000 thrill-seekers into emergency rooms with injuries last year, the government said.
An annual report by the Consumer Product Safety Commission found that 6,590 people were hurt on amusement park rides last year, down from 7,260 in 1999.
Add mobile carnival rides and a total of 10,580 people were injured, 200 more than in 1999.
Two people died last year in incidents related to amusement rides, the safety commission said. That's down from the six people who died in such incidents in 1999.
