A man with four previous drunken driving convictions who was stopped for weaving in and out of traffic on Interstate 40 was ready with an excuse for his poor driving: his passenger spilled his beer.

Not surprisingly, Christopher Lucero was arrested just before midnight Saturday, said state police officer Kurtis Ward, who said he initially thought the driver was joking.

"He was so matter of fact about it, like it wasn't a big deal," Ward said.

Lucero, 31, was allegedly too drunk to perform field sobriety tests and was arrested on aggravated drunken driving charges, court records said.

Ward found four opened bottles of beer in the car, court records showed.

It was Lucero's sixth DWI arrest. He had been found guilty of four of five previous drunken driving charges and has paid $1,750 in fines, the DWI Resource Center said.
