Allows you to judge _______, speed, and distance of other vehicles and hazards in the traffic environment c. Essential when ________, approaching a vehicle or hazard; turning, merging, and crossing intersections d.

Line-of-sight is the visible path of travel from your vehicle to the target area. a. When something obstructs your LOS, you may need to ________ your speed and/or position until it is clear again 1. Path-of-Travel is the series of continuous ____________your vehicle will occupy while traveling toward your target area 3. Target a. b. c. d. Specific object located straight ahead in the center of your path of travel Near visual field limit Steer toward Changes to whatever appears in the center of your path of travel ** Do ________stare at or fixate your gaze on the target itself… 4. Target Area a. Rather than focusing directly on the Target, continuously scan to the ____________ of it (the Target Area) for relevant information and potential hazards 5. Lane Positions: Lane positions are based upon an average lane size of 12-feet wide, and a vehicle 6feet wide Select the lane position that gives you the best line of sight and safest path of travel This Diagram shows the three basic lane positions drives can use Name: _____________________________ Block: _________ Lane Position 1 Positioned in the ________ of lane with an equal buffer of space on either side Lane Position 2 Allows for additional space to the right of the vehicle. Used to prepare for a ________ turn or when avoiding a problem to the right of the vehicle. Lane Position 3 Allows for additional space to the left of the vehicle. Used to prepare for a ________ turn or when avoiding a problem to the left of the vehicle. Name: _____________________________ Block: _________ 6. Footprint of the vehicle: a.
