In heavy rain, your tires can ride on a film of water and lose contact with the road. This hazard is known as

A hydroplaning.

On a wet road, at speeds of up to 35 mph, modern tires will usually channel water away to maintain contact with the road. However, in deep water at higher speeds, the channeling action of the tires becomes less effective and the tires start to ride on a layer of water like water skis. This is called "hydroplaning." At 50 mph or above, hydroplaning may result in a total loss of braking and steering control. To prevent hydroplaning, slow down.

I only got 2 questions wrong

In the midst of finishing up learning on the older app, it told me to download this newer version. However, I didn’t want to have to go through all those questions again, so I simply finished reviewing on the old app and took the practice test on this newer app. Upon completion of the tests, it would not let me move forward or see my score! How should I know if I have done well enough to pass if I cannot see my own score?
