When navigating a narrow urban roundabout in an articulated heavy truck (skup vozila), what lane positioning technique should the driver use?

1. Use the full width of available space, keeping the tractor toward the outside of the lane while monitoring mirrors to ensure the trailer wheels do not mount the inner curb or squeeze cyclists
2. Cut tightly across the central paved island at high speed
3. Drive exclusively in the inner lane with left wheels on the grass
4. Honk continuously to force all circulating cars to stop
