Swift, whose tractors covered 1.5 billion miles in 2010, was boosted by a 4.3 percent increase in trucking volumes and a 4.7 percent increase in average trucking rates.
Demand for freight transportation in the United States has been improving with increased manufacturing and consumer spending. Truckers have been increasing rates to offset the jump in fuel costs.
Swift's second-quarter net income was $19.6 million, or 14 cents a share, compared with a net loss of $23.1 million, or 38 cents a share, a year ago.
Operating revenue rose 16 percent to $850.5 million.
Excluding some items, profit was 18 cents a share.
Analysts on average had expected earnings of 19 cents a share on revenue of $849.1 million, according to Thomson Reuters I/B/E/S. (Reuters)
