"Governor Bush was treated at the scene and returned home and is traveling to New Hampshire this afternoon," said Linda Edwards, Bush's press secretary.
"Fortunately, I escaped injury," Bush said on CBS Early Show Tuesday. "I dove to avoid the refuse and am sore but feel great."
A Texas Department of Public Safety agent with Bush, Roscoe Hughey, was hospitalized with injuries, Edwards said.
The accident apparently occurred about 12:30 p.m. CST, Edwards said, although she said details were sketchy.
