2 CHAPTER 12 Vehicle Movement
STUDY GUIDE FOR CHAPTER 12 LESSON 1 Using Appropriate Speed Imagine that you are driving and would like to change lanes. To determine if you are driving at an appropriate speed to make the maneuver, ask yourself the following questions. After each question, write an explanation of why it is an important consideration. What is the path of travel like in the lane you are in? You need to know if the vehicles ahead of you are slowing down or stopping. What is the path of travel like in the lane you want to enter? You need to know if the lane you are entering is clear next to you and also 20 to 30 seconds ahead of you. Are other vehicles signaling to move into the lane you want to enter? It is important not to collide with other vehicles that are entering the same lane. The drivers may not see you.

3 What is happening in the lanes behind you?
You should be aware of any vehicles tailgating or coming up fast behind you. How fast are you going? Can you change lanes without exceeding the speed limit? You should not exceed the speed limit to change lanes. Do you have room to make the move safely? For you to make a safe pass, there should be a large enough gap in the flow of oncoming and ongoing vehicles. How much of a gap is there between vehicles in the lane you are moving into? You should have a safe gap between any vehicles ahead of you so that you can pull into it safely after the pass.

4 Speeding: 4 Teens Killed
Watch Speed Kills: Preventing Teen Driving Fatalities Answer Questions: “Heart and Mind” Worksheet SPEEDING STATISTICS Speed is a major factor in teen crash fatalities. Teens have the reaction time of a 70-year-old when distracted while driving. In 2008, 37 percent of fatal crashes with 15 to 20-year-old males at the wheel involved speeding. In 2008, 88 percent of speeding-related fatalities occurred on roads that were not interstate highways. Among crashes attributed to a critical teen driver error, 21 percent of serious teen driver crashes were due to driving too fast for road conditions.


6 Kevin Thomas Gilbert, 18, of Whitehouse Station, N. J
Kevin Thomas Gilbert, 18, of Whitehouse Station, N.J., died on March 12, 2011, at Robert Wood Johnson University Hospital from severe brain trauma resulting from an automobile accident. He was surrounded by his loving family and friends.

He first played with the Readington Raiders travel baseball team from 8 years to 14 years of age, where he began his outstanding start as an outfielder. They proceeded to win five state championship titles, two regional titles, and at age 13 they went onto to the Babe Ruth World Series. The Readington Raiders were the only team to date to win the Readington tournament all seven seasons. In eighth grade, the Readington Vikings had an undefeated season, going This was the first time in RMS history. Kevin also received the prestigious Andrew Levendis Award. He then began playing with the Jack Cust Baseball Academy, playing on Gold and then the N.J. Super 17 and N.J. Super 18 teams, which won many championships. In 2010, they were 17-0, winning the N.J. Super 17/18 Fall Invitational, 18U Northeast Elite Blue Chip Prospects and the Diamond Nation Wood Bat Championship. Kevin's dream was to play baseball and was being watched by pro scouts. He was recently asked to an invitation only work out with the Houston Astros. Kevin was a senior at Hunterdon Central Regional High School in Flemington, N.J. He was an honor student and played on the varsity baseball team his sophomore and junior years. They won the 2009 NJSIAA Group IV State Championship, Hunterdon/Warren County Tournament and the Skyland Conference. In 2010, they won the Hunterdon/Warren/Sussex Tri County Championship. Upon graduation from high school, Kevin was going to attend Temple University on a baseball and academic scholarship. Kevin was a wonderful son, brother and friend. He would be happy to know that he was able to help others by donating his organs to those in need. Friends may visit with the family at the Kearns Funeral Home, 103 Old Highway 28, Whitehouse, N.J., on Thursday, March 17, 2011, from 2 to 4 p.m. and 7 to 9 p.m. A funeral service will be held at the Readington Reformed Church, Readington Road, Whitehouse Station, N.J., on Friday, March 18, 2011, at 10 a.m. In lieu of flowers, a donation can be made in honor of Kevin Gilbert to the N.J. Sharing Network, Attn: Marsha Kefer, 691 Central Ave., New Providence, N.J ( or donations to the "Kevin Gilbert Scholarship Fund" and mail to: TD Bank, 1 Royal Rd., Flemington, N.J Visit for more information or to send condolences.

Total Stopping Distance For each sentence below, circle T if the statement is true and F if it is false. Correct each false statement in the space below. The amount of distance you need to stop the car increases with speed. True If you double your speed, you will need four times the distance to stop. Vehicle-braking distance is the distance your vehicle travels after you see a problem and before you apply the brakes. False - Vehicle braking distance is how far your vehicle travels between when you first apply the brakes and when it stops. Total stopping distance is the distance it takes from the moment you see a problem until your vehicle is stopped.

24 You should identify objects or conditions in your path of travel that could increase the level of risk 30 to 40 seconds ahead. False - Identify objects 12 to 15 seconds ahead of your vehicle. Between 20 and 30 seconds ahead equals about 1/2 mile at 50 mph. True The condition of the road surface affects total stopping distance. FIND OUT MORE. During the next few days, observe other people’s driving while you are riding in the school bus or another vehicle. Are drivers keeping enough space between their vehicles to allow for the total stopping distance? How much space should they be keeping in optimal conditions? How much space should they be keeping in adverse conditions? Define total stopping distance - Perception Time + Reaction Time + Braking Distance

Natural Laws and the Movement of Your Vehicle Match the following terms by placing the letter of the definition or a description of what the item does to the left of the item. c e a f b d ____ inertia friction between your tires and the road friction energy of motion traction causes objects to continue moving in a straight line momentum the point about which weight is evenly distributed kinetic energy force between two surfaces that resists the movement of one surface across the other center of gravity the product of weight and speed

27 Complete the following sentences by writing in the natural law each sentence is describing.
When you brake quickly and your books and packages on the backseat fall onto the floor, the force at work is ____________________. inertia. The force that makes your tires “stick” to the surface of the road is called ____________________. friction Two vehicles going at the same speed hit the same brick wall, but the one that weighs more sustains much more damage. This is an example of ____________________. momentum The faster a vehicle moves, the more ____________________ energy it has. kinetic The force that slows your vehicle going uphill is called ____________________. gravity

28 FIND OUT MORE. Look online or in your text book to find out about kinetic energy.
What is kinetic energy? How could it affect you when driving? Kinetic energy is a form of energy that represents the energy of motion. Energy is found in different forms, such as light, heat, sound and motion. There are many forms of energy, but they can all be put into two categories, kinetic and potential. Kinetic energy involves motion––of waves, electrons, atoms, molecules, substances, and objects. Potential energy is stored energy and also the energy of position––gravitational energy. There are also several forms of potential energy.

Natural Laws and Steering and Braking A. For each sentence below, circle T if the statement is true and F if it is false. Correct each false statement in the space below. Perception distance, reaction distance, and braking distance make up total stopping distance. True Braking is a result of friction between the brake linings and your foot. False - Braking is a result of friction between the brake linings and wheel drums or discs. Braking distance is greater on a smooth road. False - Braking distance is reduced when you drive on a smooth road. Your braking distance decreases if you are going downhill. False - Your braking distance increases if you are going downhill.

30 Your ability to steer a vehicle depends partly upon the condition of the vehicle’s suspension.
True Directional control is a vehicle’s ability to hold a straight line. A banked road is higher on the inside of curves than on the outside. False - A banked road is higher on the outside of curves than on the inside.

31 A crowned road is higher in the center of the road than on the edges.
True B. FIND OUT MORE. Look online for the definition of centrifugal force and centripetal force. What are they, and what are the differences between them? Centrifugal force – Centripetal force – Difference between them –
