Frequently Asked Questions

Get answers to critical questions about DUI charges and defense strategies in Columbia and Richland County.

Should I refuse the breathalyzer?

This depends on your circumstances. Refusal triggers automatic license suspension but may limit prosecution evidence. Call Matt McGuire at (888) 499-5738 immediately to discuss your specific situation.

What is the 30-day DMV deadline?

You must request an administrative license hearing within 30 days of arrest to contest your suspension. This deadline is absolute and cannot be extended—missing it waives your right to challenge.

Can DUI charges be dismissed?

Yes. Charges are regularly dismissed for traffic stop violations, breathalyzer errors, improper procedures, or constitutional violations. Matt McGuire has secured numerous dismissals by challenging police procedures.

Will I lose my license?

License suspension is likely without aggressive defense at both the DMV hearing and criminal case. We fight on both fronts to preserve your driving privileges and minimize suspension periods.

What if I blew over the limit?

Breathalyzer results can be challenged through calibration records, operator errors, observation period violations, and physiological factors. A reading over .08 doesn't guarantee conviction.

Can I get my charges reduced to reckless driving?

In appropriate cases, we negotiate reduction to reckless driving or other non-DUI offenses that avoid mandatory minimum penalties, license suspension, and the stigma of a DUI conviction.

What is an ignition interlock device?

For second and subsequent offenses, you may be required to install a device that tests your breath before allowing the vehicle to start. We fight to avoid or minimize interlock requirements.

How much does DUI defense cost?

Defense costs vary based on offense level and case complexity. We provide clear fee structures upfront with no hidden costs. Call for free to discuss your case and get honest estimates.
