SAN BERNARDINO, Calif. (AP) _ A man convicted 23 times of driving while intoxicated pleaded guilty to yet another drunken-driving charge.

Conrado Madrid Galindo, 64, pleaded guilty to one count of driving under the influence and one count of driving without a license. In a separate case, Galindo also pleaded guilty to a charge of carrying a loaded firearm, said Diana DeVince, clerk for Superior Court Judge Frederick Mandabach.

Mandabach sentenced Galindo to two years in Glen Helen Rehabilitation Center for Men, a county facility, for all the offenses, she said. He was ordered to surrender today.

In the latest offense, Galindo was arrested Jan. 28 when an officer noticed him driving erratically.

Records compiled by the state's Bureau of Criminal Identification and Investigation and obtained by the San Bernardino Sun, show that Galindoo has been charged with drunken driving 29 times since 1950 and had been convicted in 23 of those cases.

Galindo's attorney, Deputy Public Defender Phyllis Morris, did not return a phone call.

Last month, Arlene Joyce, executive assistant to the president of the Los Angeles chapter of Mothers Against Drunk Driving, said Galindo's case ''shows some major cracks in the judicial system that allows a person to go this many times with this many convictions without changing anything.''

MADD is a nationwide group that lobbies for laws to impose stiffer penalties on drunken drivers.
