Timberlake's lawyer, Edward Burke Jr., told the PA Media news agency on Wednesday: “I look forward to vigorously defending Timberlake against these charges.”
“We have a lot to say at the appropriate time, but we are currently awaiting a full investigation by the District Attorney’s Office,” he said.
Timberlake has been touring the United States to promote his sixth album, Everything I Thought It Was, and is set to launch an international tour starting with two nights in Poland next month.
His scheduled court date of July 26 coincides with the start of his world tour at the Tauron Arena in Krakow.
When police stopped him, Timberlake's eyes were “bloodshot and glassy” and “there was a strong odor of alcohol coming from his breath,” according to charging documents.
His speech slowed down and he performed poorly on officers' sobriety tests, according to the documents.
He added that he also refused to take a breathalyzer test.
He has previously spoken publicly about seeking help for excessive drinking.
In New York State, drunk driving charges can result in up to a year in prison, a fine of $1,000 (£786), and a driver's license suspension for at least six months.
A former member of the popular '90s boy band NSYNC, Timberlake is an actor, songwriter, and one of the world's best-selling music artists.
Timberlake performed twice in Chicago this weekend and was scheduled to perform at New York's Madison Square Garden next Tuesday.
The 10-time Grammy Award winner is also known for his roles in the films The Social Network and Friends With Benefits.
