What can lead to a license suspension for driving under the influence?

Refusing to submit to a chemical test after being arrested for driving under the influence can lead to an automatic license suspension in many jurisdictions. Laws often stipulate that by obtaining a driver's license, individuals consent to chemical testing if they are suspected of DUI. This is known as implied consent. Therefore, when someone refuses to take the test, it is viewed as a violation of this implied consent, resulting in an automatic administrative penalty, such as license suspension.

Other scenarios, such as completing the test successfully or not being involved in an accident, generally do not lead to a suspension. In fact, a successful test might demonstrate sobriety, thereby preventing any adverse action concerning the driver's license. Additionally, the fact that the arrestee was underage can lead to separate penalties, but the specific context of suspension relates more directly to the refusal of the chemical test rather than age alone.
