A man who tried to flee from officers was stopped when he crashed into a stop sign, police say.
He's expected to face court on a number of charges, including drug driving.
It was one of two incidents involving alleged drug driving in the past 24 hours outlined by ACT Policing on Wednesday morning.
In the other, a man led police on a chase that reached speeds of 149km/h and ended after police used stop sticks on the Monaro Highway.
In the first incident, police say a 27-year-old Reid man driving a silver Toyota Corolla sedan was directed to stop on Drakeford Drive, Greenway about 2.40pm Tuesday.
"The driver accelerated away north along Drakeford Drive, and collided with a stop sign at Mortimer Lewis Drive," they said in a statement.
"The man was arrested, and lodged at the ACT Watch House. He will face court this morning charged with drug driving, failing to stop, not displaying L plates and dangerous driving."
In the second incident, they say a 39-year-old Karabar man driving a white Subaru Outback was directed to stop on Ainslie Avenue, Reid, about 2am Wednesday.
"The driver accelerated away onto Limestone Avenue, Anzac Avenue and Parkes Way at speeds of up to 149km/h," they said.
"The driver proceeded south on the northbound lanes of the Monaro Highway, where police deployed stop sticks. The driver abandoned the vehicle and fled on foot, but was apprehended a short time later at a service station on Canberra Avenue."
He, too, was arrested and is expected to face court on a number of charges.
