PUTNAM COUNTY, Ind. (WTHR) - A traffic stop for Indiana's "Slowpoke Law" turned into a drug bust for a state trooper Friday.

State police say the trooper spotted an SUV driving 57 mph in the left lane of Interstate 70 eastbound in Putnam County. During a traffic stop for violating the Left Lane Law, the trooper noticed several indicators of criminal activity.

A subsequent search of the vehicle turned up 11 pounds of suspected marijuana, which has a street value of about $33,000, suspected cannabis powder, suspected controlled substance pills and a gram of suspected methamphetamine.

The occupants of the vehicle, 30-year-old Daniel Wade of Longmont, Colorado and 25-year-old Veronica McClam of Beaufort, South Carolina, were arrested on preliminary charges of dealing marijuana and possession of marijuana. McClam was also charged with possession of methamphetamine and possession of a controlled substance.

They are being held at the Putnam County Jail.
