A Tri-Met bus driver was caught speeding on Highway 30. William Haraldsen, 48, was also cited for driving erratically tailgating and not having a valid commercial license. Tri-Met's Mary Fetsch says they're normally notified when a license is expired or suspended. Fetsch says Haroldsen's license had a sticker over the expiration date, but it still wasn't valid. Haroldsen is off duty while an investigation is conducted. Videos from the bus are being reviewed and they're trying to figure out why DMV didn't notify them about the expired license.
