June 1, 2025

As a Los Angeles DUI Attorney, one of the most common questions I get is: Do police have to read me my Miranda rights during a DUI stop?

Los Angeles DUI and Miranda Warnings In Berkemer, an officer stopped a driver for erratic driving, conducted field sobriety tests, and […]

May 20, 2025

If you were arrested for DUI in Los Angeles after taking a sleep medicine like Ambien, you might ask: “Can I be guilty if I didn’t mean to drive?” A man named Terry Mathson asked that same question—and the court had a lot to say about it.

May 17, 2025

California law provides three court-authorized pathways to seek dismissal of a criminal charge through diversion: However, due to controlling case law, diversion is not permitted for DUI offenses unless the defendant qualifies for military diversion under Penal Code § 1001.80. This means that most DUI charges are categorically ineligible for dismissal through judicial or mental health diversion programs. So what happens when you’re charged with DUI and an additional offense in Los Angeles or elsewhere in California—such as drug possession, or gun possession, and you qualify for diversion on the non-DUI charge? Here, Los Angeles DUI Attorney Alex Andryuschenko explains your legal options and how courts handle these situations, especially when one charge may be eligible for diversion while the […]
