You're driving on a downtown street in an Oregon city and see a lane painted solid red with the words 'BUS ONLY' marked inside it. May you drive there to bypass slow traffic?

Red markings designate lanes where transit only vehicles may travel; they are not HOV lanes, and no rush-hour exception opens them to cars. Misreading: Confuses a solid red transit lane with an HOV lane; the manual says red markings designate where transit only vehicles may travel continuously, not high-occupancy car traffic.

That rule belongs to striped red lines, which show where you may enter the Transit Only lane to turn, park, or enter a driveway. A solid red lane is not for cars. Misreading: Applies the striped red rule (enter the Transit Only lane to turn, park, or enter a driveway) to a solid red lane, which the manual closes to cars entirely.

The conclusion is right but the reason is not. Red pavement markings designate Transit Only lanes for buses, light rail, and sometimes bikes; they do not mark fire lanes. Misreading: Reads red pavement as a fire-lane or emergency-access marking; the manual says red markings designate where transit only vehicles may travel continuously.
