You want to park on the right-hand side edge of the carriageway. How big is the mandatory minimum distance between your vehicle and the solid lane boundary line?

You answered correctly. In Germany, when parking on the right side of the road next to a solid lane boundary line (continuous white line), you must leave at least 3 meters of space between your vehicle and the solid line. This ensures that the remaining roadway stays wide enough for other vehicles to pass safely, especially emergency vehicles. Always make sure you don’t block the lane, as stopping or parking too close to the line could endanger or hinder other road users. Remember this 3-meter rule whenever you park near a solid lane line.
