While there is no direct law prohibiting the use of cell phones while driving except for drivers under the age of 18, under the state's "careless driving law," motorists commit a secondary moving violation if they use a handheld cell phone or other device for talking and listening while driving (UT Code Sec. 41-6a-1715).
