SACRAMENTO, Calif. (AP) — Adults could be helmet-free when driving certain recreational off-highway vehicles under a bill that passed the Assembly on Friday despite opposition from public health groups and the industry trade association.

AB1835 by Assemblywoman Kristin Olsen, R-Modesto, heads to the Senate after narrowly passing on a 43-21 vote, just above the threshold for approval in the 80-member chamber.
