by | Jun 24, 2026

A first DUI arrest is overwhelming—but it’s also the best opportunity to minimize damage.

Penalties for a First-Time DUI

A standard first-time DUI (BAC under 0.15%) includes:

  • Minimum 10 days in jail (9 may be suspended)
  • Fines and fees over $1,500
  • Alcohol screening and education
  • License suspension
  • Ignition interlock device
  • Plus other negatively impactful penalties

Penalties increase significantly for higher BAC levels.

Will You Go to Jail for a First DUI?

Yes—but in many cases, depending on the level of DUI offense, most jail time can be suspended if handled properly and conditions are met.

Defense Options for First-Time DUI Charges

Common DUI defenses include:

  • Lack of reasonable suspicion for the traffic stop
  • Inaccurate breath or blood testing
  • Improper police procedures
  • Violations of Constitutional rights

Early legal representation can make a major difference.
