MO HB2055

Amends the "Siddens Bening Hands Free Law" to modify state preemption of local electronic device regulations, allowing local ordinances that don't conflict with state law rather than completely superseding all local regulations

Prohibits drivers from physically holding electronic devices, texting, making calls without hands-free features, watching videos, or recording/broadcasting video while operating vehicles on Missouri highways

Establishes escalating fines: up to $150 for first offense, $250 for second offense within 24 months, and $500 for third or subsequent offenses or violations in work/school zones

Creates enhanced penalties when violations cause harm: Class D misdemeanor for property damage over $5,000, Class B misdemeanor for serious physical injury, and Class D felony for causing death

Requires law enforcement to inform drivers of their right to decline device searches during stops, and prohibits using this violation alone as probable cause for other violations or as sole basis for stopping a vehicle
