DUI Law Utah – Everything You Need to Know

Utah is recognized as one of the toughest states in the nation when it comes to DUI law. With a 0.05% blood alcohol concentration (BAC) limit, Utah has stricter rules than most states, making it essential for drivers and visitors to understand the laws, penalties, and long-term consequences of driving under the influence. This comprehensive guide explains Utah DUI laws, including penalties, license suspensions, and key legal defenses.

What Is the Legal BAC Limit Under Utah DUI Law?

Utah’s DUI law sets the BAC limit at 0.05%, the lowest in the United States.

• Standard Drivers: A BAC of 0.05% or higher can result in a DUI charge.
  
  

• Commercial Drivers: The limit is even stricter at 0.04%.
  
  

• Under 21 Drivers: Utah enforces a zero-tolerance policy, meaning any measurable alcohol can result in a DUI conviction.
  
  

This makes DUI in Utah one of the most aggressively enforced offenses in the country.
