While operating on a two-lane, two-way undivided rural road, your commercial vehicle becomes disabled 200 feet beyond the crest of a steep hill. Under standard emergency accident and stopping procedures, how must the three reflective warning triangles be deployed to account for this sight obstruction?
- Place one triangle 10 feet from the rear corner, one triangle 100 feet in front of the vehicle, and one triangle moved back between 100 feet and 500 feet toward the crest of the hill.Cevap
- BPlace the triangles at intervals of 10 feet, 100 feet, and 200 feet, all positioned exclusively behind the vehicle toward the rear.
- CPlace one triangle 10 feet in front, one triangle 100 feet ahead, and keep the final triangle exactly 100 feet behind the vehicle without adjusting for the hill crest.
- DPlace all three warning triangles along the center dividing line at 50-foot increments directly behind the vehicle.
Cevap
Place one triangle within 10 feet of the rear corner, one triangle 100 feet in front of the vehicle, and move the rear warning device back between 100 feet and 500 feet toward the crest of the hill.
On a two-way or undivided road, standard placement requires warning devices within 10 feet of the rear or front corners, 100 feet ahead, and 100 feet behind. However, when a hill, curve, or other obstruction prevents drivers from seeing the vehicle within 500 feet, the rear warning device must be moved back 100 to 500 feet down the road to provide adequate advance notice before the crest.
