Question:
The distance your vehicle travels between the time that you recognize a hazard and the time that you start to apply the brakes is known as reaction distance. For example, your foot may be on the accelerator (gas) pedal. Your brain has to decide to command your foot to move off the accelerator pedal and onto the brake pedal. If you are alert, it will take only 3/4 of a second to start to press the brake pedal. But at 75 mph, your vehicle will travel over 80 feet in that short time. Total stopping distance is the sum of perception distance (how far your vehicle travels before your brain recognizes that your eyes have seen a hazard), reaction distance, and braking distance (how far your vehicle will continue to travel once you start to brake before it finally stops).

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?
