Which vehicles may be overtaken only by maintaining a specially great lateral distance?

You answered correctly. When overtaking bicycles and motorcycles, drivers must maintain a particularly large lateral distance because these road users are more vulnerable and can be easily affected by wind turbulence or sudden swerves. Extra space ensures their safety. Trams, on the other hand, are large, stable, and run on tracks, so the rule about a specially great lateral distance does not specifically apply when overtaking them. Always remember to keep extra distance from bicycles and motorcycles when overtaking to avoid endangering them.
