What Is Driving Under the Influence (DUI)?

Driving Under the Influence (DUI) is a serious criminal offense that occurs when a person operates a motor vehicle while impaired by alcohol, drugs, or a combination of both. In California and most U.S. states, a driver is legally considered impaired when their blood alcohol concentration (BAC) is 0.08% or higher.

However, drivers can still face DUI charges even with a lower BAC if their ability to drive safely is compromised or if they are under the influence of drugs (including prescription or marijuana use).

Types of DUI Offenses

DUI charges can vary based on the circumstances of the arrest:

  • Standard DUI: Operating a vehicle with a BAC of 0.08% or more.
  • Drug DUI: Driving under the influence of controlled or prescription drugs.
  • Underage DUI: Drivers under 21 with any measurable BAC (zero tolerance).
  • Aggravated DUI: Cases involving injury, death, or multiple prior offenses.

Penalties for DUI

DUI penalties depend on whether it’s a first-time offense or a repeat violation. In California, consequences may include:

  • First Offense:
    • Fines between $390–$1,000 (plus court fees)
    • 48 hours to 6 months in county jail
    • 6-month driver’s license suspension
    • DUI education program (3–9 months)
  • Second Offense:
    • Up to 1 year in county jail
    • License suspension for 2 years
    • Mandatory DUI school and ignition interlock device (IID)
  • Felony DUI:
    • Prison sentence of up to 3 years (or more for injury cases)
    • License revocation
    • Higher fines and stricter probation terms

Penalties may increase if the offense involved injury, property damage, or a minor in the vehicle.

Bail for DUI Arrests

Bail amounts for DUI charges depend on the severity of the case:

  • First Offense (No Injuries): $5,000–$10,000
  • DUI With Injury: $25,000 or more
  • Felony DUI: $50,000–$100,000+

Posting bail allows the defendant to be released from jail while awaiting trial, giving them time to prepare their defense.

How a Bail Bond Can Help

If you can’t afford to pay the full bail amount, a bail bond offers an affordable solution. A licensed bail bond agent can post bail on your behalf for a non-refundable fee—usually 10% of the total bail.

Benefits include:

  • Faster release from custody
  • Affordable payment options
  • 24/7 availability
  • Guidance through the legal process
