4. What distance will your vehicle travel before it comes to a complete stop at 70 mph? Reactionary Distance Braking distance Total Distance 10/22/2015 4

5. What is Reactionary Distance and how much time does it consume?

6. What distance does your vehicle travel at 20, 40, 60, 70, and 100 mph? Have you ever thought about that distance? Formula 1.466 x your speed = feet per second 20 mph = 29.32 feet per sec. 40 mph = 58.64 feet per sec. 60 mph = 87.96 feet per sec. 70 mph = 102.62 feet per sec. 100 mph = 146.6 feet per sec. So every 4 seconds at 60 mph you have traveled 351.84 feet over the length of a football field. Keep 4 seconds in mind for later. 10/22/2015 6

7. Why is it important to know the distance you are traveling? It enables us to be more effective at threat evaluation, stopping distance, collision avoidance, etc… At 20 mph you are traveling 29.32 feet per second and it takes you.75 of a second to react how much distance have you covered? 15 feet at 20 mph, the child stepped out at the front of a car and you were 1.5 car lengths away when the child stepped out are you able to stop prior to hitting the child? 10/22/2015 7

8. How far in front of your vehicle do the vehicle’s low beams project out on an average? So we stated earlier that a vehicle moving 70 mph travels 102.62 feet per second. On a good day your lights project out between 150 to 200 feet, doesn’t leave much time if something bad happens. So if you are on the low end 150 feet and you are moving 102.62 feet per second there is only about 47 feet left to react in, is that enough. 10/22/2015 8

9. How far in front of your vehicle do the vehicle’s high beams project out on an average? So we stated earlier that a vehicle moving 70 mph travels 102.62 feet per second. On a good day you lights project out between 250 to 300 feet, doesn’t leave much time is something bad happens. So if you are on the low end 150 feet and you are moving 102.62 feet per second there is only about 47 feet left to react in, is that enough. 10/22/2015 9

13. So we stated earlier that a vehicle moving 70 mph travels 102.62 feet per second. If your eyes are off the road for just 4.3 seconds you have traveled 441.26 feet. That is almost 1 and ½ football fields. That is a long time for something to happen. We all have done it. 10/22/2015 13

14. If you are involved in collision avoidance where should you be looking? Where you want the vehicle to go. 10/22/2015 14
