Phones and texting
Drivers may not use a hand-held phone or device to write, send or read texts, instant messages or email while driving. Hand-held calls are not banned by state law, and Wyoming has no separate phone rule for permit or intermediate drivers.

Seat belts and child seats
Every driver and passenger must wear a seat belt, and the driver must make sure passengers under 12 are buckled. Enforcement is secondary: police may not stop a vehicle only for a belt violation. Children under 9 must ride in a child safety restraint, in a back seat when one is available.
Official wording (4 sources)

wyoleg.gov“No motor vehicle shall be halted solely for a violation of this section.”
wyoleg.gov“no person shall operate a passenger vehicle in this state unless each child who is a passenger in that vehicle and who has not reached his ninth birthday is properly secured in a child safety restraint system in a seat of the vehicle other than the front seat,”
wyoleg.gov“The lap and shoulder belts of the vehicle will fit properly across the collarbone, chest and hips of the child and the belts do not pose a danger to the neck, face or abdominal area of the child in the event of a crash or sudden stop.”

Move Over law
When a parked emergency vehicle, or a stopped or slow (under 20 mph) municipal, utility, or highway construction or maintenance vehicle, is showing its warning lights, move to the lane farthest from it or at least one lane away on roads with two or more lanes your way. On a two-lane road posted 45 mph or more, slow to 20 mph below the posted limit.

School buses
Traffic from either direction must stop before reaching a stopped school bus with flashing red lights and wait until the bus moves or the lights go off.

After a crash
Notify police immediately by the quickest means if a crash injures or kills anyone, or damages a vehicle so badly it can't be driven normally and safely: city police inside a town, otherwise the Highway Patrol or county sheriff. The officer files the written report; drivers no longer file their own written report.
