Difficulty: Very hardAccident Procedures

You are operating a commercial motor vehicle on a divided highway when a collision disables your truck in the right travel lane, exactly 140 feet beyond a sharp, blind curve. Smoke is beginning to emerge from under your closed engine hood, and an occupant from another vehicle is lying on the pavement nearby with a severely bleeding leg. After immediately activating your four-way flashers, what is the correct comprehensive sequence and method to manage this scene?

  1. Keep the hood closed, prepare your fire extinguisher, and place warning triangles toward approaching traffic at 10 feet, 100 feet, and place the third triangle back beyond the blind curve. Next, notify authorities, and then apply direct pressure to the victim's wound without moving them.Answer
  2. B
    Open the hood slightly to locate the fire's source and extinguish it. Place your three warning triangles toward approaching traffic at exactly 10 feet, 100 feet, and 200 feet. Notify authorities, then carefully move the injured occupant to the median for safety.
  3. C
    Assist the injured occupant first since life safety is paramount. Because you only confirmed having two warning triangles during your pre-trip inspection, place them at 10 feet and 100 feet toward approaching traffic, then notify authorities regarding the collision and smoke.
  4. D
    Immediately use your hand-held mobile phone to call emergency services while walking to check on the victim. Once the call is connected, place warning triangles at 10 feet in front of the truck, and 100 feet and 200 feet behind it, then check the engine.

Answer

The correct comprehensive procedure is to protect the scene by preparing the extinguisher while keeping the hood closed, placing the warning triangles toward approaching traffic (modifying the 200-foot placement to beyond the blind curve), notifying authorities, and finally caring for the injured by applying direct pressure without moving them.
The correct response perfectly synthesizes four distinct CDL protocols. First, it follows the mandatory accident priority sequence: protect the area, notify authorities, and care for the injured. Second, it correctly addresses engine fires by leaving the hood closed to starve the fire of oxygen. Third, it correctly applies the divided highway rule (placing all devices toward approaching traffic) while appropriately utilizing the obstruction exception by moving the furthest triangle beyond the blind curve. Finally, it provides the correct first aid response by applying direct pressure to bleeding without moving the victim.

Step-by-Step Solution

1
Protect the area by addressing immediate hazards and increasing visibility.
The fire risk is monitored without feeding it oxygen, and approaching drivers are warned before they enter the blind curve.
Preventing secondary collisions and explosions is the absolute highest priority at an accident scene.
2
Notify authorities of the exact location and situation.
Emergency services and first responders are dispatched.
Professional medical and fire mitigation help is required to safely resolve the incident.
3
Care for the injured person by applying direct pressure to the wound.
Severe bleeding is controlled while the victim remains stationary.
Stopping bleeding saves lives, but moving a victim can severely worsen underlying spinal or structural injuries.
