However, he drove on the wrong side of the road and over a roundabout, causing several vehicles to take evasive action to avoid a collision.
Hewson continued to drive west, crossing onto the wrong side of the road for long periods and at times didn't even react to on-coming vehicles while he was in the wrong lane.
After stopping the ute other motorists approached the vehicle, and prevented him from driving.
When police arrived Hewson was in a stupefied state and when it was established he was not under the influence of alcohol he was asked to undergo drug impairment tests, but was unable to do so because of his stupefied state. A nurse's attempt to take a blood sample from him to check for drugs was unsuccessful do to extensive scar tissue on his veins. A doctor then established Hewson was in no fit state or capable of driving.
Hewson told police he had taken valium and methadone.
He was fined $750, ordered to pay $132 in court costs and banned from driving for 12 months and one day.
Also convicted of driving under the influence of drugs in Northland recently was Karlina Joyce Oppert, 24, who was fined $630, ordered to pay $771 in analysis fees and disqualified from driving for six months after she had cannabis in her system.
