POST Emergency Vehicle Operations 3 — Questions and Answers
Question 1: Under POST guidelines, 'due regard' in emergency vehicle operations means:
- Following all traffic laws without exception
- Driving as fast as the situation demands regardless of conditions
- Operating with the care a reasonable and prudent person would use given the circumstances (Correct answer)
- Yielding right-of-way to all civilian vehicles at all times
Correct answer: Operating with the care a reasonable and prudent person would use given the circumstances
'Due regard' is the legal standard requiring officers to drive with the same caution a reasonable, prudent person would show under emergency conditions.
Question 2: Which factor is considered MOST critical when deciding to initiate a vehicle pursuit?
- The speed of the fleeing vehicle
- The seriousness of the offense versus the risk to the public (Correct answer)
- Whether a second officer is available to assist
- The distance from the nearest police station
Correct answer: The seriousness of the offense versus the risk to the public
POST policy requires officers to weigh the severity of the known offense against the danger a pursuit poses to innocent third parties before initiating.
Question 3: The 'reactionary gap' in emergency vehicle operations refers to:
- The distance a vehicle travels while the driver perceives a hazard and applies brakes (Correct answer)
- The space maintained between the patrol car and the suspect vehicle
- The delay between activating lights and the siren engaging
- The time needed for backup units to arrive on scene
Correct answer: The distance a vehicle travels while the driver perceives a hazard and applies brakes
The reactionary gap is the distance covered during the perception-reaction time before the brakes are physically applied, typically adding several car lengths to total stopping distance.
Question 4: When an officer is driving in a pursuit and loses sight of the suspect vehicle, the officer should:
- Increase speed to reacquire the suspect as quickly as possible
- Immediately terminate the pursuit and return to patrol
- Reduce speed, maintain safe driving, and advise dispatch of last known location and direction (Correct answer)
- Request a helicopter and continue at pursuit speed until airborne support arrives
Correct answer: Reduce speed, maintain safe driving, and advise dispatch of last known location and direction
When sight is lost, the officer should slow down, drive safely, and provide dispatch with all available information for coordination — not blindly accelerate.
Question 5: What is the recommended tire pressure check frequency for patrol vehicles used in emergency operations?
- Once a month during scheduled maintenance
- Only when the tire pressure monitoring light activates
- At the beginning of each shift before the vehicle is deployed (Correct answer)
- Every 5,000 miles as part of routine service
Correct answer: At the beginning of each shift before the vehicle is deployed
Pre-shift vehicle inspections, including tire pressure checks, are required before deployment so any deficiency can be corrected before emergency operations.
Question 6: During emergency driving, overhead obstacles such as bridges and overpasses pose a risk to which vehicle equipment?
- Push bumpers and front grille guards
- Roof-mounted lightbars and antennae (Correct answer)
- Undercarriage and axle components
- Side-view mirrors and door handles
Correct answer: Roof-mounted lightbars and antennae
Low clearances at bridges and overpasses can strike roof-mounted lightbars, antennae, and other equipment, potentially disabling emergency signaling systems.
Question 7: When is it appropriate for an officer to use a median crossover or U-turn during emergency response?
- Whenever it is the fastest route to the call location
- Only when the crossing is paved and sight distances are adequate to do so safely (Correct answer)
- At any point designated as an emergency vehicle turnaround by the agency
- Only with supervisor approval obtained via radio before the maneuver
Correct answer: Only when the crossing is paved and sight distances are adequate to do so safely
Median crossovers are permissible when the surface is suitable and the officer can see clearly enough to cross safely without endangering other vehicles.
