Aggravating Factors That Increase Penalties

Certain circumstances can make DUI charges more severe:

Prior DUI offenses within 10 years

If reckless behavior is involved, you could also be charged under Reckless Driving and Road Rage Laws.

Administrative vs. Criminal Penalties

In Alaska, you could face two separate actions after a DUI arrest:

Administrative License Actions: The DMV may suspend your license automatically if you fail or refuse a chemical test.
Criminal Court Actions: Separate penalties like fines, jail time, and treatment programs ordered by a judge.

Refusing a chemical test could result in penalties under Alaska’s Implied Consent Law, even without a DUI conviction.

License Reinstatement After DUI

Install an ignition interlock device (if required)

If your license was revoked due to DUI, understanding the Alaska License Suspension Laws is essential.
