How to Defend against a DUI or DWI Charge

Challenge the legality of the traffic stop

An essential aspect of defending against a DWI charge is determining whether the traffic stop itself was legal. Law enforcement officers must have reasonable suspicion to pull you over. If you can prove that the officer lacked reasonable suspicion or probable cause to make the traffic stop, any evidence collected during the stop may be deemed inadmissible in court.

Dispute the accuracy of field sobriety tests

Field sobriety tests are often administered by law enforcement officers to determine if a driver is under the influence of alcohol or drugs. However, these tests are not always accurate and can be affected by factors such as fatigue, medical conditions, and even the footwear the person is wearing. By challenging the accuracy of the field sobriety tests, you may be able to cast doubt on the prosecution’s case.

Question the reliability of breathalyzer tests

Breathalyzer tests are commonly used to measure a driver’s blood alcohol content (BAC). However, these devices can sometimes produce inaccurate results due to improper calibration, device malfunction, or even operator error. A skilled DWI attorney can challenge the reliability of the breathalyzer test results, which could weaken the prosecution’s case.

Present an alternative explanation for the observed impairment

If the arresting officer observed signs of impairment, such as slurred speech, bloodshot eyes, or unsteady gait, it’s crucial to present an alternative explanation for these symptoms. Medical conditions, allergies, fatigue, or even emotional stress can all cause similar symptoms. Providing a plausible explanation for your observed impairment can help to cast doubt on the DWI charge.

Seek expert witnesses

Expert witnesses can play a significant role in the outcome of a DWI case. A toxicologist, for example, can testify to the accuracy and reliability of the chemical tests used to determine your BAC. Additionally, a medical expert can provide testimony on how certain medical conditions or medications may have affected your appearance or behavior during the traffic stop.
