Question:
Which of the following is true about hydroplaning?
A
Hydroplaning can start at speeds as low as 35 mph.
explanation
Hydroplaning occurs when you drive too fast over standing water and effectively ski over its surface. Even with good tires, your vehicle can start to hydroplane at speeds as low as 35 mph. (Badly worn tires can cause the vehicle to hydroplane at speeds as low as 25 mph.) This may send your car into a skid. If you hydroplane, try to avoid accelerating, steering, or braking; let the car slow itself down. Do not use your cruise control on wet roads. If your vehicle loses traction, the cruise control may spin the wheels to try to maintain a constant speed. This can worsen or even cause a skid.

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?
