Hydroplaning doesn't happen often. But it can if your
tires do not have much tread or it the pressure in one or
more is low. It can happen if a lot of water is standing
on the road.
If
you can see reflections from trees,
telephone poles or other vehicles, and raindrops
"dimple" the water's surface, there could be
hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn't a hard and fast rule about hydroplaning.
The best advice is to slow down when it is raining.
Driving Through Deep Standing Water
Notice: If you drive too quickly through deep
puddles or standing water, water can come in
through your engine's air intake and badly damage
your engine. Never drive through water that is
slightly lower than the underbody of your vehicle. If
you can't avoid deep puddles or standing water,
drive through them very slowly.

If you try to drive through flowing water, as you
might at a low water crossing, your vehicle can
be carried away. As little as six inches of
flowing water can carry away a smaller vehicle.
If this happens, you and other vehicle
occupants could drown. Don't ignore police
warning signs, and otherwise be very cautious
about trying to drive through flowing water.
