Guam Chauffeur's License Study Guide

How can the driver anticipate a change in traffic signals as he approaches an intersection? - Look well ahead for stale green lights, to avoid running through late. If your vehicle is 38 feet in length, what "timed-interval" count would you use under ideal road and traffic conditions? - 4 seconds. Round to nearest 10 feet and divide by 10. What conditions should the driver consider when deciding upon a safe driving speed? - 1. Road condition (rain) 2. Tire condition (tread, inflation) 3. Brake condition (adjustment) 4. Light condition (glare, shadows) 5. Visibility condition (dusk, rain, smoke, dust) 6. Traffic density (vehicles, pedestrians, cyclists) 7. Load condition (weight, length, width, type) 8. Driver condition (fatigue, tension) In what way does the slow driver create a traffic hazard? - Slow drivers create hazards from vehicles following too close or trying to pass them, which increases their risk of an accident from the rear and the side. In what way does the fast driver create a traffic hazard? - Fast drivers increase their chance for collision by reducing stopping distance and increasing driving fatigue What is the minimum following distance the driver of a commercial vehicle maintains when following another commercial vehicle outside of a business or residential district? - 200 feet, 2 second rule, take car length to the nearest ten feet and divide by 10, 1 car length per 10 mph What is the most effective way to deal with a "tail-gater"? - Make sure to observe them carefully and help them to safely pass you. What is the surest method of reducing stopping distance? - Drive slower. What is meant by "The Danger Zone" of a vehicle? - The area in front of the vehicle in which it cannot stop What defensive measures can the driver take as he approaches any intersection? - 1. Never enter an intersection at a speed at which you cannot stop safely. 2. Do not assume you have the right of way. 3. Look well ahead for stale green lights. 4. Position your vehicle into the proper lane well before the turn at the intersection. 5. Do not depend on other drivers. 6. Never pass at the approach to or in an intersection. If the weight of the vehicle is doubled, how many times must the stopping power be increased? - 2x If the speed of the vehicle is doubled, by how many times must the braking force be increased to stop the vehicle? - 4x If the weight and the speed of the vehicle is doubled, by how many times must the braking force be increased to stop the vehicle? - 8x How many braking systems are required on every truck, truck-tractor or bus? - Two: the service brake and the parking brake. What is the best method of applying the brakes: On a wet road surface? To check the speed down a slight grade? To check the speed down a steep grade? - 1. Lightly snub the breaks to prevent the wheels from locking. 2. By snubbing the breaks. 3. Select the lower gear ratios and with a steady break application What determines the "safe speed" to proceed down any hill? - The speed which will allow safe stop at any time. What is the purpose of an engine governor? - To keep an engine's RPM within safe limits. Are engine retarders more effective at low engine R.P.M. or high R.P.M? - Higher RPM What should the driver do when it becomes necessary to drive his vehicle through the water which is upon the highway? - Place a slight drag on the breaks Why should you avoid overtaking another vehicle when your difference in speed is only slight? - The time to overtake is considerable and creates hazards Why should you not signal another vehicle to overtake and pass you? - You may be encouraging a driver with limited experience to over-drive his/her ability. What action should the driver take when he is being overtaken by a smaller vehicle? - Help them complete their pass, reduce your speed if necessary. What is the advantage of "double clutching" when shifting gears? - It allows you to get the engine's RPM up with the clutch out. To proceed down a steep grade, at which point should the driver gear down? - Before proceeding down the steep grade.
