The 8 MPH marked on the box is the official safety recommended speed, not the maximum speed the cart can physically roll.
Driving over 8–10 MPH constantly with this trailer will cause trailer sway, unstable steering, longer braking distance, and easily lead to tip-over or accidents.
High speed also puts extra pressure on the hitch, frame and wheels. Long-time fast riding may cause structural damage, crack or detachment and safety hazards.
