Utah's DUI threshold is 0.05% BAC - the lowest of any state in the country. Most states use 0.08%. That difference matters: two drinks can push a driver over the limit in Utah when the same amount would be legal elsewhere.
The Utah DLD written exam tests both the 0.05% threshold and the zero-tolerance 0.00% standard for drivers under 21. The Utah driver's handbook, published by the Utah Driver License Division, covers both thresholds, the Little Cottonwood Canyon chain law, and GDL permit ..

Utah's Wasatch Front inversion events trap cold air in Salt Lake Valley for days or weeks in winter. Reduced visibility and degraded air quality follow.
The handbook addresses this with specific speed recommendations and headlight protocol. The I-15 corridor through Salt Lake City and the I-80 canyon approach from the east are the primary routes affected. Southern Utah's canyon roads on US-89 and US-191 are a completely different driving environment. Flash flood washes cross the road. High-clearance considerations affect which routes are passable after heavy rain.
0.05% Is Not a Typo: Utah's DUI threshold is 0.05% BAC - legally enforceable and tested on the DLD exam. For a 150-pound person, that threshold can be reached after approximately two standard drinks consumed within an hour. The exam tests the 0.05% number because it's different from every other state and because drivers from other states consistently assume Utah follows the national 0.08% standard.
From Salt Lake City's I-15 inversion corridor to the canyon roads of southern Utah on US-89, the Utah driver's handbook covers what Utah roads - including the lowest DUI threshold in the country - require.
