MOT Incident Management & Response 2 — Questions and Answers
Question 1: When an incident occurs within a work zone, what is the FIRST action the MOT supervisor should take?
- Notify the media
- Secure the scene and protect responders from traffic (Correct answer)
- Begin documenting damages
- Contact the project owner
Correct answer: Secure the scene and protect responders from traffic
Securing the scene and protecting responders from moving traffic is always the first priority to prevent secondary crashes.
Question 2: Which agency typically serves as the Incident Commander during a major highway incident involving hazardous materials?
- FHWA
- Fire department (Correct answer)
- State DOT
- Towing company
Correct answer: Fire department
The fire department typically assumes Incident Command for hazardous materials incidents due to their specialized training and equipment.
Question 3: A 'secondary crash' in incident management refers to:
- A crash that occurs in the same lane as the original incident
- A crash caused by rubbernecking unrelated to the work zone
- A crash that occurs as a direct result of traffic backed up from the primary incident (Correct answer)
- Any crash requiring emergency medical services
Correct answer: A crash that occurs as a direct result of traffic backed up from the primary incident
Secondary crashes occur in traffic queues that form behind the primary incident, often due to reduced visibility or abrupt stops.
Question 4: What does 'clearance time' mean in the context of incident management?
- Time for all emergency vehicles to arrive
- Time elapsed from incident detection until all lanes are open to traffic (Correct answer)
- Time required to notify the public about the incident
- Time needed to complete the accident report
Correct answer: Time elapsed from incident detection until all lanes are open to traffic
Clearance time measures how quickly responders restore normal traffic flow from the moment the incident is detected.
Question 5: When establishing a Temporary Traffic Control (TTC) zone around a crash scene, the upstream taper should be placed:
- Directly at the crash vehicle
- Far enough upstream to allow drivers time to merge safely before the blockage (Correct answer)
- Immediately past the incident
- Only on the shoulder
Correct answer: Far enough upstream to allow drivers time to merge safely before the blockage
Placing the upstream taper well in advance gives drivers sufficient reaction distance to merge before reaching the blocked area.
Question 6: Which of the following best describes the 'unified command' structure used in major incidents?
- A single agency makes all decisions without input from others
- Multiple agencies share command responsibilities while maintaining a joint action plan (Correct answer)
- The DOT directs all emergency responders
- Command is transferred to the agency with the most personnel on scene
Correct answer: Multiple agencies share command responsibilities while maintaining a joint action plan
Unified command allows multiple agencies to coordinate under a shared plan while each retains authority over its own resources.
Question 7: What is the primary purpose of a 'quick clearance' policy in incident management?
- Reduce documentation requirements for minor crashes
- Minimize roadway clearance time to restore traffic flow and reduce secondary crashes (Correct answer)
- Allow tow trucks to bypass weigh stations
- Eliminate the need for law enforcement at minor incidents
Correct answer: Minimize roadway clearance time to restore traffic flow and reduce secondary crashes
Quick clearance policies prioritize rapid removal of crash vehicles to reopen lanes and reduce the risk of secondary collisions.
