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.

Driving Through Flowing Water

CAUTION:

Flowing or rushing water creates strong forces. 
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 the other vehicle occupants
could drown. Don’t ignore police warning signs,
and otherwise be very cautious about trying to
drive through flowing water.

Some Other Rainy Weather Tips

Besides slowing down, allow some extra following
distance. And be especially careful when you pass
another vehicle. Allow yourself more clear room
ahead, and be prepared to have your view restricted
by road spray.

Have good tires with proper tread depth. See “Tires”
in the Index.
