Wal-Mart trucks have been involved in 380 crashes in that time, federal data show. Nine people have been killed; 129 have been injured.

It's unclear how Wal-Mart's safety record compares with other carriers. The company did earn the government's highest safety rating when it was last reviewed a decade ago.

Wal-Mart has 6,239 trucks and 7,222 drivers, according to the Federal Motor Carrier Safety Administration. They drove 667 million miles last year.

The Bentonville, Arkansas, company is one of the largest private carriers in the U.S., after Coca-Cola, Pepsi and food service company Sysco, according to Transport Topics, an industry newspaper.
