How would a law enforcement officer ask a Spanish speaker "How may I help you?"

The phrase “¿En qué puedo servirle?” translates to “How may I help you?” in a direct and polite manner. It is a formal way of offering assistance that reflects respect and courtesy, which is essential in a law enforcement context. This phrase is especially appropriate when engaging with a Spanish speaker, as it conveys a willingness to assist in a clear and professional way.

The other choices, while they may serve different conversational purposes, do not fit the context of offering help. “¿Cómo estás?” translates to “How are you?” and is more of a greeting than an offer of assistance. “¿Qué tal?” can also mean “What’s up?” or “How’s it going?” and is similarly informal. As such, they do not effectively communicate the intent of helping the person in need, making “¿En qué puedo servirle?” the most suitable choice for this scenario.
