NEED FOR SAFETY Unit D Use explanatory models

NEED FOR SAFETY Unit D: Use explanatory models from their own learning in science or personal experience to distinguish between scientific and personal opinion and to analyze the need for safety systems and regulations

Where we are going… list the factors influencing the ability to make sudden stops assess the need for staying a safe distance behind another automobile when travelling at highway speeds discuss the consequences of a shorter or longer reaction time list traffic safety factors list and describe ways that passengers can protect themselves from injury in accidents identify and analyze the dangers faced by people in a motor vehicle accident compare the death and injury rate in motor vehicle accidents to other causes of death and injury among adults and teenagers

list the factors influencing the ability to make sudden stops Reaction Time! � This is the time it takes you to recognize a problem and act on it What are some things that could impair your reaction time?

Reaction time while driving Distractions: Fatigue Drugs Alcohol

Alcohol Determined by Blood Alcohol Concentration (BAC) The law = 0. 08, that means there is 0. 08 mg of alcohol in each m. L of blood. One drink = 45 m. L of hard liquor (40%), 150 m. L of wine (11%) or 350 m. L of beer (4%) Someone’s BAC needs to take into account; body weight, rate of drinking, tiredness, hunger. http: //www. transportation. alberta. ca/2137. htm

BAC till I can drive next? Pg. 242 How soon can a drinker drive?

assess the need for staying a safe distance behind another automobile when travelling at highway speeds What is a safe distance?

Safe distance You are traveling 10 m behind another car. Your both travelling at 100 km/h. The person in front of you slams on their breaks to avoid hitting a deer, they stop within 15 m. How long do you have to respond? Do you think that you would hit the other car?

Safe distance You are traveling 10 m behind another car. Your both travelling at 80 km/h. The person in front of you slams on their breaks to avoid hitting a deer, they stop within 15 m. How long do you have to respond? Do you think that you would hit the other car?

Safe distance You are traveling 10 m behind another car. Your both travelling at 60 km/h. The person in front of you slams on their breaks to avoid hitting a deer, they stop within 15 m. How long do you have to respond? Do you think that you would hit the other car? What if you were impaired? Or distracted?
