In a letter to members of the Wisconsin state legislature, CFA and its allies ask legislators to vote down two identical bills AB504/SB 381, which would relax current restrictions on the engine size of ATVs that children under 12 can ride from 90 to 130 cubic centimeters and allow children 12 to 16 to drive utility vehicles with engines up to 200 cubic centimeters. Noting that there is no evidence that children are capable of safely operating such powerful machines, the Legislature should be wary of allowing younger children to operate more powerful vehicles without evidence that it is safe and without evidence that these changes will not lead to more deaths and injuries.
