We wrote these practice questions from the facts in the Utah Driver Handbook (2026 edition (Driver-Handbook-2026.pdf on dld.utah.gov, last modified 2026-08-27, 115 PDF pages; lists new laws effective May 6, 2026), read 2026-11-09. Page numbers cited are PDF pages (PDF page = printed page + 10). Where the handbook is silent or out of date, the Driver License Division pages on dld.utah.gov and the Utah Code on le.utah.gov (Titles 41 and 53, read 2026-11-09) are the source. Handbook statements that differ from the current Utah Code and were left out of the questions: child restraint 'eight and under' (Utah Code 41-6a-1803: younger than eight) and 'a citation for each unrestrained passenger' (41-6a-1803(3): one offense); driving without insurance 'class B misdemeanor' (41-12a-302(3), amended 2026: class C); failing to stop at an injury crash 'third-degree felony' (41-6a-401.3(4): class A misdemeanor unless aggravated); a DUI plea held in abeyance (41-6a-502(7): a plea may not be held in abeyance); ignition interlock periods of three years under 21 and 10 years for automobile homicide (41-6a-518.2(2): two and four years); and the age-16 night restriction in the handbook table (41-8-2: younger than 17; the questions use a 16-year-old). edition) and from official sources on road signs. Every answer links to its source, so you can check it and read more.
