Which of the following best describes the consequence of refusing an alcohol test?

Refusing to take an alcohol test, which is a breath, blood, or urine test, carries serious consequences under Texas law. When someone refuses to submit to testing, it results in an automatic suspension of their driver's license for 180 days. This is part of Texas's implied consent laws, which state that by driving in the state, a driver has already agreed to take these tests if requested by law enforcement during a suspected DUI stop.

The rationale behind this strict penalty is to deter individuals from driving under the influence and to encourage compliance with testing, which helps enforce driving laws and improve road safety. This consequence aims to underscore the seriousness of driving while intoxicated and the importance of accountability by drivers.

In contrast, the other options presented do not reflect the legal ramifications of refusing an alcohol test in Texas. The mention of a warning, 90-day suspension, or mandatory attendance in a workshop is inconsistent with the established penalties linked to test refusal, highlighting the necessity for drivers to understand and comply with alcohol testing regulations.
