Under what circumstance can a driver's license be suspended for a suspected DUI?

The correct response regarding the suspension of a driver's license for a suspected DUI is rooted in the concept of implied consent laws. These laws state that when a driver applies for a license, they implicitly agree to submit to chemical testing if suspected of driving under the influence. If an arrestee refuses a chemical test, the authorities have the legal grounds to suspend the driver's license because their refusal is viewed as an indication of guilt or an attempt to evade the assessment of their sobriety.

This scenario is designed to encourage compliance with law enforcement procedures intended to keep roads safer. Consequently, the refusal to undergo testing can lead to automatic penalties, including license suspension, without the need for a criminal conviction related to DUI.
