During a nighttime haul on a multi-lane divided interstate, your rig is involved in a collision. You manage to steer safely onto the right shoulder and bring the truck to a complete halt. Your in-cab mobile communications are fully functional, and you observe that the driver of the other vehicle has sustained injuries. In accordance with strict commercial driving protocols, arrange your required post-accident actions in the precise chronological order they must be executed.
- 1Activate your vehicle's four-way hazard flashers to establish immediate perimeter visibility.
- 2Utilize your in-cab mobile phone to report the exact location and severity of the incident to emergency dispatch.
- 3Exit the tractor while securely holding the reflective warning triangles between your body and oncoming traffic.
- 4Position the warning triangles at intervals of 10 feet, 100 feet, and 200 feet facing the direction of approaching vehicles.
- 5Approach the other involved vehicle to apply direct pressure to any bleeding wounds without moving the victim.
Answer
The correct sequence is to immediately activate flashers, call emergency services from inside the cab, exit while holding the warning triangles for safety, place the triangles at 10, 100, and 200 feet, and finally administer basic first aid to the victim.
While the general macro-sequence of accident response is Protect, Notify, Care, the official CDL manual outlines a critical micro-sequence exception: if you possess a mobile phone, you must call for help BEFORE exiting your vehicle. Therefore, the exact sequence requires activating flashers (initial protection), calling authorities from the cab (notify), exiting while holding triangles for personal safety, placing those triangles at 10, 100, and 200 feet (complete protection), and only then tending to the injured.
