4th Offense Felony Drunk Driving Penalties in Wisconsin

New Penalties for Your 4th OWI in WisconsinFourth OWI Penalties Wisconsin

Previously in Wisconsin a 4th offense OWI was considered a misdemeanor if it had been more than five years since the last OWI conviction. 

As of 2018, your 4th DUI offense in Wisconsin is an automatic Class H felony charge with severe penalties: 

  • Up to $10,000 in fines
  • Lifetime driver’s license revocation with no possibility of occupational license for convictions within 15 years of each other
  • 1-3 years required ignition interlock device in vehicle
  • 60 days to 6 years in jail
  • Absolute sobriety required for occupational license
  • ‘Driver improvement’ surcharge of $435
  • Travel ban to Canada and problems traveling abroad in European Union

Furthermore, the Excessive BAC Escalator may double, triple or quadruple the maximum sentence depending on your BAC level at the time of your DUI arrest. You will also deal with the surcharges, alcohol assessment, high risk insurance requirement, and other penalties imposed for first, second, and third DUI convictions. 

 You Are Only Guilty If You Are Convicted®

If you had a minor under the age of 16 in your vehicle at the time of your 4th Wisconsin DUI arrest, the penalties are doubled:

  • Up to $20,000 in fines
  • 120 days to 12 years in jail
  • 4-6 years license revocation
  • 4-6 years with a required ignition interlock device in your vehicle
  • Absolute sobriety required for occupational license

If your BAC is over .17 at the time of your 4th DUI arrest in Wisconsin, you face significantly harsher penalties outlined by the Excessive BAC Escalator:

  • BAC .17 to .199 - Penalties Double
  • BAC .20 to .2499 - Penalties Triple

A Fee-to-Plea™ Lawyer Will Say, “There’s Not Much You Can Do.” Be Wary!

Tactics an experienced DUI lawyer can use to get your charges reduced or dropped:

Your traffic stop was illegal – If you were stopped without due cause, you have grounds to fight your OWI charge. A good lawyer can call into question the arresting officer’s motivations. If there was no legitimate reason for pulling you over in the first place, the officer made an illegal stop.

Time of Test for BAC – Your BAC actually goes up after you stop drinking as the alcohol makes its way into your bloodstream. Grieve Law has successfully leveraged this technique to calculate that our client was not in fact over a threshold while driving. The client would’ve been home in time if not for being pulled over!

Improper Field Sobriety Test – The state of Wisconsin has strict standards for field sobriety tests. If the equipment wasn’t properly calibrated or the procedures were not completely followed and accurately evaluated, you have a case for fighting your DUI charges.

You CAN fight felony drunk driving charges, but a Fee-to-Plea™ lawyer won’t want to. Grieve Law attorneys will examine your 4th OWI charges and determine the best defense against a felony conviction.
