Brief Description of Driving Safety Hazard Driving through a yellow light is like risking yourself. There is a reason why there are 3 lights. Green is to tell you its safe to go, yellow is telling you that you CAN go but recommended you slow down to a crawl or if you do pass, be caution, and red is don’t go because it’s dangerous. People think speeding up to get past a yellow light will help them get on with their day, but there is a bigger danger with trying to get past a light when they can’t wait 20 seconds of their life for a light.

** Statistics or News Articles Related to this Hazard ** “I n 2006, approximately 887 people were killed and 144,000 were injured in as many as 171,000 red light running crashes. Survivors of red light running crashes include people who are injured as well as the family and friends of people who are injured or killed in red light running crashes. “  [] ** How the Kinematics (principles of motion) Relate to This Hazard ** In passing a light, acceleration is more like a death wish instead of stopping or passing. If you accelerate trying to get through, you would either make the yellow light and collide with another car or stop suddenly taking the people behind you to start a domino effect.

** Example Scenario ** Harrison is at a stoplight getting ready to drive north. He accelerates from rest to a speed of 20 m/s in 20 s. The next stoplight is 50 meters away and it changes from green to yellow in 20s and yellow to red in red in 4s. Does he make it past the red light?

Acceleration: Now that we have the acceleration, starting velocity, time, and displacement, we can use the formula to find how far the car has gone in 20 seconds.

According to these calculations, not only does Harrison make it past the stoplight during the yellow light, but he also gets out of the intersection and into the next block before the light even turns red. We know because the origin is the stoplight and if he is south from the stoplight, it means he hasn’t even passed the stoplight yet and needs to past it. He travels 200meters but this equation tells use where he ends up and he ends up 150m past the stoplight.

This scenario is to show what people need to do in the road. I look at the assignment in a different direction, instead of doing a collision, i did what people should do in the street to avoid a collision. My view on this is to just drive normally in the road, that's why in my scenario, Harrison doesn't accelerate or speed up at all. If your driving the speed limit in the street, you should just go constant speed so you don't have to force the breaks and damage your car in the process, and if your going the speed limit, you have time to slow down if you didn't make the stop light. It's only 20 seconds of your life that you need to waste instead of getting in a crash and paying thousands for surgery and stressing out your family.

 * How this Hazard Can Be Avoided With a Better Knowledge of Kinematics **

this is an **x vs. t** graph. As you can see the starting displacement is -50 and after 20 seconds, it reaches 150m. Just drive normally is all I have to say. There is no real danger in driving your way as long as it's safe and approved by the law.
