Under Massachusetts General Laws Chapter 90, Section 21 (ULIARS), which offense is arrestable in the presence?

• A. Arrest
• B. Uninsured operation
• C. Unlicensed operation of motor vehicle
• D. Illegal operation of motor vehicle

Answer: (C)

The key idea here is on-scene arrest authority for specific traffic offenses. In Massachusetts, certain motor-vehicle violations are designated as arrestable in the presence, meaning an officer may take a person into custody on the spot when the offense is witnessed, without a warrant. Chapter 90, Section 21, known as ULIARS, lists offenses that qualify for this immediate enforcement. Driving with no valid license is one of those on-scene arrestable offenses. When an officer observes unlicensed operation, there is a direct violation of licensing requirements that justifies detaining the driver on the scene to ensure safety, verify identity, and address the licensing status before allowing the vehicle to proceed. This immediacy is what makes it the best choice. Other options represent either broader actions or offenses not singled out for on-scene arrest in this statute. Arguably, uninsured operation and illegal operation can be enforced in other ways and aren’t the specific on-scene arrest triggers highlighted by this statute in the same way as unlicensed operation.
