With these ATVs unavailable to families, we may see more kids on adult ATVs. We know this leads to crashes. The CPSC, the ATV industry, consumer groups, safety advocates and parents all agree: It's critical to keep riders under the age of 16 off of large ATVs designed for adults. The CPSC, consumer advocates and industry have worked for years to get kids onto youth-model ATVs, many of which are now not available because of the unintended consequences of this legislation. In addition, families with smaller dirtbike enthusiasts may be tempted to put young riders on motorcycles that are too large for them. This also raises the risk of injury.
