Move Over law
When you approach a stopped emergency vehicle with flashing red or blue lights, a tow truck or highway maintenance vehicle with flashing amber lights, or any stopped vehicle with hazard lights on, slow down, give it as much room as you can, and move out of the next lane if it's safe.

School buses
Stop for a school bus with flashing red lights, whether you're behind it or meeting it, and wait until the red lights stop. Slow down for flashing amber lights. Oncoming traffic need not stop on a divided highway, on a road of five or more lanes, or where a signal or officer controls traffic.

Motorcycle permit rules
A Utah motorcycle learner permit is valid for six months and needs a Class D license (or CDL) plus the motorcycle knowledge test, so the minimum age is effectively 16. For the first two months: no highways posted over 60 mph, no passengers, and no riding 10 p.m.-6 a.m.
Official wording (5 sources)
“may issue a motorcycle learner permit effective for six months to an applicant who: (a) holds an original or provisional class D license, a CDL”
le.utah.gov“the operator of a motorcycle holding the motorcycle learner permit may not operate a motorcycle: (i) on a highway with a posted speed limit of more than 60 miles per hour; (ii) with any passengers; or (iii) during the nighttime hours after 10 p.m. and before 6 a.m.”
le.utah.gov“A temporary learner permit can be issued if the applicant is at least 16 years old, has a valid Class D or Commercial Driver License, and has passed the vision test and the required motorcycle written test.”
dld.utah.gov“Anyone younger than 19 years old must hold the motorcycle learner permit for two months. The two-month requirement may be waived upon proof of completion of the Basic Rider Course (BRC).”
dld.utah.gov“A Beginning Rider Course is required for all riders. True or False”

Lane splitting
Lane splitting (riding between moving cars) is illegal in Utah, but lane filtering is legal: a motorcyclist may pass stopped vehicles in the same lane at 15 mph or less on roads with a limit of 45 mph or less, or on an off-ramp, when it is safe.
Official wording (3 sources)
“An individual may engage in lane filtering only when the following conditions exist: (a) the individual is operating a motorcycle”
le.utah.gov“on a roadway with a speed limit of 45 miles per hour or less; or (ii) on an off-ramp; (d) the individual is not on an on-ramp; (e) the vehicle being overtaken in the same lane is stopped; (f) the motorcycle is traveling at a speed of 15 miles per hour or less; and (g) the movement may be made safely.”
le.utah.gov“Lane splitting is riding between cars moving at higher speeds and is illegal in Utah and considered dangerous.”
