When do most ambulance crashes occur?

Most ambulance crashes occur when lights and sirens are in use because this scenario often involves driving at high speeds in response to emergencies. When emergency vehicles activate their lights and sirens, they typically navigate through traffic and require right-of-way privileges, which can lead to increased risks. The dynamics of high-speed driving, coupled with the urgency of reaching a scene quickly, can result in accidents, especially in situations where other drivers may not adequately see or hear the approaching ambulance.

In contrast, operating without lights and sirens generally involves following normal traffic laws, thus reducing overall risk. Similarly, when the ambulance is parked or responding to non-emergency calls, the potential for collision is significantly lower due to the reduced interaction with moving traffic. This understanding highlights the importance of cautious driving practices even during emergency responses to mitigate risks associated with high-speed travel.
