Proven DUI Defense Strategy

Each case is unique. Thomas crafts a custom strategy based on the specifics of your arrest. Common defense tactics include:

1. Challenging the Legality of the Stop

If law enforcement lacked probable cause, evidence may be inadmissible.

2. Contesting Field Sobriety Test Validity

Sobriety tests are often flawed or administered incorrectly. Thomas will challenge these results.

3. Investigating Chemical Test Procedures

Were breath or blood tests conducted properly? Thomas inspects calibration records, chain of custody, and lab protocols.

4. Examining Police Conduct

Were your rights violated during the arrest? If so, Thomas will seek to have the charges reduced or dismissed entirely.
