Cultural Tip
German speakers often prefer the verb 'müssen' (must) when talking about required speed for safety or regulations, e.g., 'Wie schnell muss ich fahren?'. 'Brauchen' sounds a bit more informal and is common in everyday conversation. Also, be aware that speed limits are strictly enforced in Germany, so asking about the correct speed is practical and appreciated.
