SAN ANTONIO (AP) _ Tejano singer-songwriter Pete Astudillo has been arrested on a charge of driving while intoxicated after police say he crashed his SUV into a row of traffic barriers.

Astudillo was released Sunday afternoon after posting $1,000 bond.

As he left the San Antonio magistrate's office, Astudillo signed autographs and posed for pictures in the parking lot.

Police say Astudillo was driving his Chevrolet Suburban west on North East Loop 410 Saturday night when the SUV crashed into the traffic barriers near the McCullough exit.

Witnesses told police they saw the SUV strike nine sand-filled barrels, then continue traveling along the shoulder until it struck a concrete barrier, a police report said.

Astudillo suffered minor scratches.

The report said Astudillo submitted to an alcohol breath test, which showed that his blood-alcohol content was 0.24 _ three times the legal limit.

After he was released, Astudillo denied he was drunk.

``There's a difference between being totally wasted and having a glass of wine,'' he said, adding, ``Nobody's perfect; we all make mistakes. I don't condone drinking and driving.''

The 41-year-old Laredo native was a longtime backup singer and songwriter for Selena y Los Dinos in the early 1990s. He launched a solo career in 1994, but found little success.

However, after Selena's death in 1995, his song ``Como Te Extrao'' (Oh How I Miss You), which he said he wrote as a tribute to his mother and Selena, became a smash hit, reaching No. 2 on the Billboard Hot Latin Tracks chart.
