  1. A
    1 hour
  2. 2 hoursAnswer
  3. C
    3 hours
  4. D
    4 hours

Answer

2 hours
The adverse driving conditions rule allows a commercial driver to drive for up to 2 additional hours beyond the standard 11-hour limit (for a total of up to 13 hours) and extends the 14-hour driving window by up to 2 hours to reach safety or complete the trip.

Step-by-Step Solution

1
Identify the applicable regulatory exception for unexpected severe weather.
The scenario describes the adverse driving conditions provision under Hours of Service (HOS) rules.
Unforeseen adverse conditions allow drivers extra time to reach a safe stopping location or complete their run safely.
2
Recall the exact extension limit granted under this rule.
Federal rules grant up to 2 additional hours of driving time and up to 2 additional hours to the driving window.
This relief extends the standard 11-hour driving limit to a maximum of 13 hours under qualifying unexpected conditions.
