MOT Safety Protocols & Incident Management 4 — Questions and Answers
Question 1: A worker is injured and unresponsive in the travel lane. After calling 911, the next priority is to:
- Begin CPR immediately in the lane to avoid moving the victim
- Warn and slow approaching traffic to prevent secondary incidents (Correct answer)
- Photograph the scene for the incident report
- Wait for emergency services without altering any traffic devices
Correct answer: Warn and slow approaching traffic to prevent secondary incidents
Protecting the injured worker from additional vehicle strikes by warning approaching traffic is critical to prevent secondary injuries or fatalities.
Question 2: Under MUTCD guidelines, the maximum spacing between channelizing devices in a taper for a 45 mph zone is approximately:
- 20 feet
- 40 feet
- 80 feet (Correct answer)
- 120 feet
Correct answer: 80 feet
For a 45 mph posted speed, the MUTCD recommends channelizing device spacing of approximately 1 foot per mph of speed, so roughly 45 feet in the taper — with 80 feet being a common maximum for tangent sections.
Question 3: A site safety audit of a work zone is MOST effective when conducted:
- Only at project kickoff before work begins
- Randomly and at varying times without prior notice to workers (Correct answer)
- Once per month on a fixed schedule
- After every significant rain event only
Correct answer: Randomly and at varying times without prior notice to workers
Unannounced, random audits capture actual working conditions and are more effective at identifying real compliance issues than scheduled inspections.
Question 4: What is the primary purpose of an 'End Road Work' sign placed at the downstream end of a work zone?
- To indicate where workers must clock out
- To alert drivers they are returning to normal roadway conditions (Correct answer)
- To mark the location where speed limits return to posted limits
- To identify where the contractor's liability ends
Correct answer: To alert drivers they are returning to normal roadway conditions
The 'End Road Work' sign informs drivers that the work zone has ended and normal driving conditions resume ahead.
Question 5: Thermal burns from equipment contact in a work zone are categorized under which OSHA recording category if they require medical treatment beyond first aid?
- Near-miss incident
- OSHA recordable injury (Correct answer)
- Property damage incident
- Environmental hazard report
Correct answer: OSHA recordable injury
Any work-related injury requiring treatment beyond first aid, including burns treated by a medical professional, must be recorded on the OSHA 300 log.
Question 6: When a lane closure must be extended beyond the originally planned time, the contractor should FIRST:
- Continue working and notify the owner at the end of the shift
- Notify the contracting authority and update traffic control as needed (Correct answer)
- Remove all workers from the zone until formal approval is received
- Post a social media alert about the extended closure
Correct answer: Notify the contracting authority and update traffic control as needed
The contracting authority must be notified promptly when lane closures will exceed approved windows so they can coordinate with traffic management.
Question 7: Which of the following work zone features specifically helps prevent vehicles from intruding into the work space at high speed?
- Advance warning signs
- Concrete barrier or positive protection (Correct answer)
- Portable variable message signs
- High-visibility flagging tape
Correct answer: Concrete barrier or positive protection
Concrete barrier and other positive protection devices physically prevent errant vehicles from entering the work space, unlike signs or tape which only provide warnings.
