A man who was pulled over in Queens during a routine traffic stop was arrested after cops found bomb-making materials in his car, authorities said.

The driver, who has not been identified, was pulled over in Jamaica at about 2 p.m. after a cop spotted him illegally crossing a lane, sources told The Post.

The officer arrested the driver, who is in his 30s, after spotting a car battery, fertilizer and glass jars with aluminum shavings inside—materials commonly used to make bombs.

The man was taken to the 113th Precinct stationhouse for questioning. Sources said the FBI was notified of the arrest.

The NYPD has been on heightened alert since 9/11 to be on the lookout for suspicious activities.
