Final answer:
A second refusal to take a blood or breath test can have serious consequences, including the suspension or revocation of the driver's license and potentially more severe penalties if convicted of DUI.
Step-by-step explanation:
A second refusal to take a blood or breath test can have serious consequences, especially for individuals suspected of driving under the influence of alcohol or drugs. In many jurisdictions, such a refusal could result in the suspension or revocation of the individual's driver's license, regardless of whether they are eventually found guilty of DUI. Additionally, a second refusal can be used as evidence against the individual in court and may result in more severe penalties if they are convicted of the offense.
