Narrative:

Controller issued taxi clearance to runway 25. I taxied across runway 25 to get to parallel taxiway before being cleared across. Cause: new company radio-taxi procedures and casual radio procedures at leb. Ie, we are commonly told to back taxi entire runway, or cleared for takeoff, or position and hold from initial call up, so we're not in habit of more complete instructions from ground.
