NY law makes it clear that it's unlawful to have a rifle with cartridges in the chamber or magazine in or on a motorized vehicle. Doesn't matter whether it's on or off road and "motorized vehicle" includes ATV's, side by sides, snowmobiles, tractors etc.. The ONLY EXCEPTION is a motorized boat when engaged in the act of waterfowl hunting and even then the motor must be shut off for it to be legal.
