1 Driving Vocabulary Absolute Speed Limit: It is the maximum or minimum posted speed limit at which one may drive under normal conditions in good weather. Actual Physical Control: To have the ability to move a vehicle of which you have actual physical control. A person can be charged with “Driving Under The Influence” (DUI) of alcohol or some other drug if they have the ability to move their vehicle.

2 Driving Vocabulary Advisory Speed Limit: Generally a yellow and black road sign that advises us of unique conditions. A speed limit that advises drivers than an adjusted speed is necessary for a short period of time. (Ex. sharp curve ahead, road work ahead, school bus stop ahead. (ABS) Anti-Lock Braking Systems: A system of braking that does not allow the wheels to lock.

3 Driving Vocabulary Basic Speed Law: Any speed below the absolute speed limit that is safe for existing road, weather, or traffic conditions. Preamufacea: A speed limit that changes at different times of the day (ex. school zone) Blind Spot: An area beside or behind your vehicle in which you cannot see even with the use of a mirror.

4 Driving Vocabulary BAC (Blood Alcohol Concentration): A formula to determine the amount of alcohol in your system. There are three BAC tests that are legally binding. They are breath-most common, blood-most accurate, and urine-legal but seldom used. Note: Levels vary from state to state, in Alabama the legal limit is .08%. Carbon Monoxide: Odorless, colorless gas given off by burning fossil fuels. Carbon monoxide very dangerous. Note: Many people die each year from breathing this gas. Most are teens or young adults sitting in parked vehicles.

5 Driving Vocabulary Centrifugal Force: One of seven natural laws that cannot be broken. A natural law that tends to push a vehicle out of a curve into a straight path. Contrast Sensitivity: How our eyes adjust to light. The ability to see under difficult conditions. Disc-Brake System: The old form of brakes where a drum pushes against a flat surface.

6 Driving Vocabulary DUI (Driving Under The Influence): Driving under the influence of any mind altering drug. This includes alcohol, prescription and non-prescription drugs, marijuana, hallucinogenic drugs, and any other drugs that alter the brain. Note: In Alabama you can be arrested and taken to jail for BAC of .05% even when the legal limit for adults (21 and over) is .08%.

7 Driving Vocabulary Hand Positioning: Most experts want their students to drive with their hands at ten and two. This gives drivers optimal control of the vehicle. Hand Over Hand Steering Push, Pull, Feed Highway Hypnosis: A trance like state or drowsiness that can occur with little warning. Usually occurs after long hours behind the wheel. Note: We have all heard of crashes where a single vehicle leaves the road and crashes. In most cases, Highway Hypnosis is to blame.

8 Driving Vocabulary Hydroplaning: A condition in which the tires of a moving vehicle ride on a cushion of water causing loss of control in both steering and braking. Three factors that lead to hydroplaning; Rain, Speed, and Tire Tread. You can hydroplane in dry conditions at 50 MPH if you hit a wet spot in the road. Partial hydroplaning begins at 35 MPH in wet conditions. At 55 MPH you will be driving on a cushion of water.

9 Driving Vocabulary Implied Consent: The law stating that any licensed driver cannot legally refuse to be tested for alcohol or drug use while behind the wheel or in “actual physical control” of a vehicle. Over Driving Your Head Lights: Driving so fast at night that a driver is unable to stop within the range of their head lights. Driving too fast to stop in the distance you can see ahead.

10 Driving Vocabulary Peer Influence: Formally known as Peer Pressure. Research has shown that more young people are victims of the influence of bad habits than of actual pressure from one’s peers. (ex. John Doe began to smoke pot because those around him did, not because he was forced). Reversible Traffic Lane: A traffic lane where the flow of traffic may change during different times of the day.

11 Driving Vocabulary SIPDE
S – Scan or Search. It’s the first component of defensive driving. I – Identify. Finding potential problems in our path of travel. P – Predict. Making a judgment to hold our current speed and course D – Decide. Deciding what action is going to minimize/avoid that potential conflict. E – Execute Your Decision.

12 Driving Vocabulary Space Margin: Keeping a safe distance around all sides of your vehicles. A cushion of space a driver tries to maintain around their vehicle. Space margin distance increases as speed goes up. Note: a safe following distance for good weather is about 2 seconds behind the vehicle in front of you. As the weather becomes worse your space cushion will need to increase. Keeping a safe space margin around your vehicle is an ongoing task.

13 Driving Vocabulary Synergistic Effect Of Combining Two Or More Drugs: Most people do not understand the effects of ingesting two or more different kinds of drugs. (Ex. Taking a barbiturate, which depresses the brain and central nervous system, and washing it down with a drink or alcohol does not double the effect as many think; it can multiply the effects as much as ten times.

14 Driving Vocabulary Total Stopping Distance: It is the distance to bring a vehicle to a complete stop from the time of perception until the wheels actually stop rolling. 3 Components: 1) Perception Time, 2) Reaction Time, 3) Actual Braking Distance. Tracking: Steering; keeping a vehicle steadily and smoothly on a desired course.

15 Driving Vocabulary Visual Acuity: A driver’s ability to see clearly under the normal conditions. Factors that affect visual acuity: Alcohol Drugs (legal & illegal) Fatigue Poor Weather Smoking inside the vehicle Dirty Window

16 Driving Vocabulary Velocitizing: The sensation of moving more slowly than one actually is as a result of driving at a fast speed for a long time. Following Distance: A minimum of 2 seconds is the required distance from a vehicle in front of you in normal driving conditions. Safe Cushion: Cushion of space around the vehicle. Driver can only control cushion of space in front of them.
