Types of 3-Wheel ATVs
Three-wheeled all-terrain vehicles, or ATVs, often referred to as "tri-ATVs," were formerly popular off-road vehicles distinguished by their unique configuration of one wheel in the front and two in the rear. Despite being banned in the United States in 1987 due to safety concerns, particularly their tendency to tip over, they maintain a devoted following in other countries and among ATV enthusiasts in the U.S.
Historical Note: The ban on sales of new 3-wheel ATVs in the United States was enacted through a consent decree with the Consumer Product Safety Commission. However, riding existing 3-wheel ATVs remains legal, contributing to their collectible status.
