There is no specific "age limit" for Test Track at EPCOT, but there are strict safety requirements based on height and supervision. All riders must be at least 40 inches (102 cm) tall to participate. Regarding age, children under the age of 7 must be accompanied by a person age 14 or older to board the attraction. For safety reasons, it is recommended that guests be in good health and free from high blood pressure, heart, back, or neck problems, or other conditions that could be aggravated by the high-speed maneuvers and sudden stops. Because the ride reaches speeds of 65 mph, parents of younger children often utilize the "Rider Switch" service, which allows one adult to wait with a child who does not meet the height requirement while the rest of the party rides, then swap places without waiting in the full line again.
