How Likely Is Jail Time For First DUI?

Jail time is still mandatory for a DUI in California, even if it is your first DUI. You could still face prison sentences for up to six months even if no one was injured. Jail time is mandatory for even first-time offenders because of Section 23536 of the Vehicle Code, which states that an individual must spend 96 hours in county jail, while 48 of those hours must be continuous. Under section 23536, a judge can still modify jail times for those that are granted probation. Even though jail time is mandatory, a judge can waive your jail time in lieu of successfully completing three to five years of probation, including DUI classes.

Sentences Enhancements For a DUI

Your sentence could be enhanced if any of the following occurred in your DUI:

  • Drunk driving with a passenger under the age of 15
  • DUI leading to injury of another and or death
  • Refusing chemical or breathalyzer tests
  • Blood Alcohol Concentration greater than 0.14%

What are the Penalties For a First-Time DUI?

Understanding what to expect in the event of being pulled over can help you ensure that your rights are protected. It is important to remember to remain polite with police but avoid admitting guilt and do not agree to a search. Police officers have been known to say things to force people into searches, but the truth is that the officer only asks to conduct a search if they are not within their legal rights to search your vehicle or person.

If you have been arrested for a first-time DUI, your conviction could include the following:

  • $1,800 to $2,600 in fines
  • 48 hours to six months in jail
  • 30-day to six-month driver’s license suspension
  • Vehicle impoundment
  • Mandatory alcohol treatment program
  • Mandatory interlock breath device for your car

These punishments can vary depending on the age, Blood Alcohol Content (BAC), and previous convictions of the driver.

Hear it From A Few
Of Our Clients

  • I would recommend Mr. Castillo without any reservation.

    “Ernie Castillo was highly recommended to us. I researched and interviewed a few attorneys before making a decision of who we were going to select. It's so tough selecting when you're skeptical with the horror stories of attorney's not feeling the passion for their work but the money. After long conversations my husband and I decided to go with Ernie to represent our son in a serious case with multiple charges. We were not disappointed at all. Mr. Castillo expertise exceeded our expectations. His was thorough, he kept us up to date on the case, answered all our questions, returned our calls in a timely manner, he's truly a genuine and sincere person. Most of all his knowledge in handling the case was remarkable. I can't express thanks enough to Ernie for the spectacular job he did defending my son who was facing years in jail. He took a stressful situation and relieved it with a positive outcome. I would recommend Mr. Castillo without any reservation.”


  • I can't thank Ernie enough for investing his time and sincere efforts to helping my family out. He truly is a master of his craft.

    “A few years back, Ernie Castillo represented a family member of mine who was charged with a vehicular offense. Although minor compared to the high profile cases Ernie is accustomed to, Ernie took the case with the utmost professionalism and was able to reduce the charge so that my family member's record was not affected. I can't thank Ernie enough for investing his time and sincere efforts to helping my family out. He truly is a master of his craft.”


  • I would highly recommend Mr Castillo to anyone.

    “Mr Castillo represented me on a criminal case in which I was falsely accused in 2012. He took over the case from a previous lawyer who was less aggressive and not actively pursing my defense. Mr Castillo is a confident, aggressive and very persistent lawyer. He kept my family and I up to date on the case and also returned our calls on time. Mr Castillo persuaded me not to take any deal and wanted take the case to trial because he was confident that he would win. With the Lord's guidance and Ernie's aggressiveness my case was dismissed. I would highly recommend Mr Castillo to anyone.”
