  3. C
    For 24 hours following the incident, regardless of when the test is administered
  4. D

Answer

For 8 hours following the incident, or until the test is completed
Under FMCSA regulations (49 CFR § 382.209), any commercial driver required to undergo post-accident testing is prohibited from consuming alcohol for 8 hours following the crash, or until the post-accident alcohol test is administered, whichever occurs first.

Step-by-Step Solution

1
Identify the regulatory mandate for post-accident testing waiting periods.
FMCSA regulations under 49 CFR 382.209 govern driver conduct following a qualifying crash.
Federal safety rules prevent post-crash alcohol consumption from contaminating or masking toxicology results.
2
Determine the maximum timeframe a driver must abstain from alcohol while waiting for the test.
The regulation specifies an abstinence window of 8 hours post-crash or until the alcohol test is completed, whichever happens first.
An 8-hour window matches the maximum allowable window for administering a post-accident alcohol test.
