HB 2553 Missouri House · 2026 Regular Session

Establishes provisions relating to child safety on motorcycles and motortricycles

HB 2553, known as "Calvin's Law," requires children under 10 to wear protective headgear and ride only on motorcycles with proper passenger seats and foot pegs (unless a licensed physician certifies a medical exemption). It prohibits children under 10 from riding as passengers unless they can place both feet on foot pegs. Violations carry fines up to $100, with higher penalties ($100) for cases involving children under 10. The law also mandates that all riders under 26 wear protective headgear while operating or riding motorcycles. It takes effect January 1, 2027.

Introduced House Committee Substitute · 4 edits
MODERATE
This bill was amended to combine three related bills (HB 2553, 1831, and 2328) into a single committee substitute. The most significant policy change is the increase in the maximum fine for motorcycle violations involving children under ten from $100 to $500. Additionally, the bill now explicitly requires that any passenger seat used by a child must have a back providing reasonable support, and the enforcement fine for violating the seat requirement was reduced to $50.
Scope change
The bill's scope was expanded by merging three separate bills into one legislative package.
