Yamaha YFM90RY Owner's Manual page 59

Know the terrain where you ride. Ride cautiously in
unfamiliar areas. Stay alert for holes, rocks, or
roots in the terrain, and other hidden hazards
which may cause the ATV to upset.
WARNING
Go slowly and be extra careful when operating
on a paved paved road or motorway. You can
collide with another vehicle. In many areas, it
is illegal to operate ATVs on public streets,
roads and highways.
WARNING
Do not operate on excessively rough, slippery
or loose terrain until you have learned and
practiced the skills necessary to control the
ATV on such terrain. Failure to use extra care
when operating on excessively rough, slippery
or loose terrain could cause loss of traction or
ATV control, which could result in an accident,
including an overturn.
