MPOETC Emergency Vehicle Operations 4 — Questions and Answers
Question 1: Which factor has the GREATEST effect on a vehicle's braking distance during emergency operations?
- Tire brand and manufacturer
- Vehicle speed at the time braking begins (Correct answer)
- Weight of the officer and equipment
- Engine size and horsepower
Correct answer: Vehicle speed at the time braking begins
Braking distance increases exponentially with speed — doubling speed roughly quadruples the distance required to stop.
Question 2: When operating an emergency vehicle at night, officers must account for the phenomenon known as 'overdriving headlights,' which means:
- The headlights blind oncoming drivers more severely at night
- The vehicle is traveling faster than the headlights can illuminate the road ahead for safe stopping (Correct answer)
- Emergency lights overpower standard headlights, reducing forward visibility
- High beams cause glare in the pursuit target's mirrors
Correct answer: The vehicle is traveling faster than the headlights can illuminate the road ahead for safe stopping
Overdriving headlights means the vehicle's speed exceeds the distance illuminated by headlights, so the officer cannot stop before reaching an unseen hazard.
Question 3: Pennsylvania Act 120 EVOC training emphasizes that the decision to initiate a vehicle pursuit is ultimately the responsibility of:
- The dispatcher who receives the call for service
- The shift supervisor who authorizes the pursuit
- The individual officer who initiates the pursuit (Correct answer)
- The department's legal counsel
Correct answer: The individual officer who initiates the pursuit
While supervisors manage and can terminate pursuits, the initiating officer bears primary responsibility for the decision to begin a pursuit.
Question 4: A police officer notices that a fleeing vehicle has entered a highway moving in the wrong direction. The officer should:
- Continue pursuit at the same speed to close the distance quickly
- Immediately terminate the pursuit due to extreme danger to innocent motorists (Correct answer)
- Request a helicopter and continue pursuit at a safe distance
- Activate PA system to warn oncoming traffic only
Correct answer: Immediately terminate the pursuit due to extreme danger to innocent motorists
A wrong-way pursuit on a highway creates an extreme and immediate risk of head-on collisions with innocent motorists, typically requiring immediate termination.
Question 5: What does 'controlled tire deflation device' (CTDD or spike strip) deployment require from officers?
- Deployment only by the pursuing officer from behind the suspect vehicle
- Safe positioning away from the path of the deflating vehicle, with advance warning to other units (Correct answer)
- Deployment only after pursuit has been authorized by a captain
- Placement only on divided highways with medians
Correct answer: Safe positioning away from the path of the deflating vehicle, with advance warning to other units
CTDD deployment requires the deploying officer to position safely out of the deflating vehicle's likely path, with other units warned to avoid the area.
Question 6: During emergency response, how should an officer handle a railroad grade crossing?
- Proceed at full speed since emergency vehicles have absolute right of way over trains
- Slow down, check for trains in both directions, and cross only when safe (Correct answer)
- Stop and radio the railroad company before proceeding
- Always wait for a second officer to escort through the crossing
Correct answer: Slow down, check for trains in both directions, and cross only when safe
Emergency vehicle exemptions do not apply to railroad crossings — officers must treat them with full caution because trains cannot stop quickly.
Question 7: What is the significance of 'secondary crashes' in the context of emergency vehicle pursuits?
- Crashes that occur after the pursuing officer's vehicle is damaged
- Crashes involving innocent parties caused by the fleeing vehicle or the pursuit itself (Correct answer)
- Collisions between two police units responding to the same incident
- Any crash occurring more than one mile from the pursuit termination point
Correct answer: Crashes involving innocent parties caused by the fleeing vehicle or the pursuit itself
Secondary crashes involve innocent motorists or pedestrians harmed as a result of the pursuit activity, and are a primary metric used to evaluate pursuit policies.
