Utah — full brief

Utah’s electric-unicycle section, § 41-6a-1121, says an individual may not operate an electric unicycle “at a speed of greater than 28 miles per hour or in violation of Subsection 41-6a-1115.1(3).” The clause regulates operating speed. It does not itself impose a limit on the wheel’s maximum design capability or establish that a faster-capable wheel is lawful.

28 mph is a ceiling where the EUC provision applies. The same section applies the chapter’s bicycle provisions to an EUC, requires reasonable and prudent speed in crosswalks, and refers to § 41-6a-1115.1(3). Applicable lower limits and prudent-speed duties still govern. Geographic reach, local access, overlapping vehicle categories, registration, insurance and modifications remain separate questions; this row does not grant access to every road, path or trail.

The definitions section changed version on October 1, 2026. The predecessor was superseded on October 1 and carries Chapter 295, 2026 General Session. The successor is effective October 1 and carries Chapter 292, 2026 General Session. Subsection (24) is unchanged: one wheel; an electric motor using gyroscopes and accelerometers to stabilize the rider; and an operator facing the direction of travel. Neither version adds a numerical wattage limit or a design-speed limit to that EUC definition. This comparison concerns subsection (24), not a claim that all definitions or cross-references in that section are unchanged.

Source provenance: The EUC operating section’s standalone PDF is unchanged from the September source record. Its archive remains the April 22, 2026 Part 11 compilation, which carries the same section heading, body and history but omits the standalone effective-date heading. The successor definition is a separate citation; the predecessor is retained in the historical record.
