What is the crash rate per 100,000 when no patients are on board?

• A. 7.0 per 100,000
• B. 16.5 per 100,000
• C. 0.7 per 100,000
• D. 70 per 100,000

Answer: (A)

Crashes per 100,000 trips is a standard way to compare risk across different situations by normalizing for how often the vehicle operates. It’s calculated by (number of crashes / number of trips) × 100,000. When no patients are on board, you’re looking at the baseline driving risk of EMS units operating without the added complexity of patient transport.

In this scenario, the data shows the rate as 7.0 crashes per 100,000 trips. That means about 7 crashes for every 1,000,000 trips. The other numbers would imply different counts or trip volumes (for example, 0.7 per 100,000 would require ten times as many trips for the same number of crashes, and 70 per 100,000 would require many more crashes or fewer trips).

So the best answer is 7.0 per 100,000 because it matches the defined rate for the no-patients-on-board condition.
