After a qualifying fatal crash, within what time window must the alcohol test be attempted, and what happens if it cannot be done in that window?
- A.Within 8 hours; if it is not done, attempts stop and the reason must be documented
- B.There is no time limit for alcohol testing
- C.Within 30 minutes in all cases
- D.Within 48 hours, with no documentation needed
Correct answer
A. Within 8 hours; if it is not done, attempts stop and the reason must be documented
Why
The alcohol window is short because alcohol leaves the body quickly, so the regulation sets 8 hours and then closes it with a written explanation. The drug test window is longer, at 32 hours, for the same type of qualifying crash.
