“A municipal ALS equipped engine and a third service county ALS ambulance were dispatched by the same dispatch, on the same radio channel, to a local park for a trauma patient. While enroute, and less than two miles from our station, we approached a heavy traffic intersection, which is blind to the south side. Upon approach, the [brand deleted] signal preemption system (which both the engine and ambulance are equipped with) was delayed in capturing the light. The driver of the engine began to reduce speed and decelerate toward the intersection. As we approached the intersection we captured the light with the signal preemption system, giving us a GREEN light, but for whatever reason, the driver of the engine made a complete stop at the intersection. Just then the ambulance blew through the intersection, not stopping for the RED light. To our surprise, we didn’t hear or see this ambulance until they were in the intersection. Only because of the driver’s situational awareness and intuition (gut feeling) did we come to a complete stop to avoid a collision.”
- Many departments now have specific rules requiring units to stop at all red lights during emergency response. If your department has such rules in effect, are there any other recommendations for intersection travel to consider?
- The reporter states the driver’s “situational awareness and intuition” contributed to collision avoidance. How large of a role do you believe the two factors played? How do you promote/teach the effect of the “gut feeling” in your driver training sessions?
- How often do you encounter intersection situations with crossing emergency vehicle traffic? Given your estimate, what is your assessment of the likelihood of a collision based on the frequency?
- If your agency uses traffic pre-emptive signaling, how often is the system calibrated/fault-checked to ensure accuracy?
- How many “blind side” intersections exist in your response area? What is the significance of knowing where they are?
