Quiz questions for HOS Rules
The new hours-of-service (HOS) rules will go into effect September 29, 2020. You may have had the rules down cold before the changes — do you still? Here are a few quiz questions to help sharpen your understanding of these rules.
- A driver starts his or her day at 7:00 a.m. The driver works in the warehouse loading trucks until noon, and then begins driving to deliver a load 8 hours away. When does the driver need to take a 30-minute break from driving?
- Can the above driver log 15 minutes on duty for fueling and then 15 minutes of off-duty time and call it a “30-minute break?”
- A driver starts split logging. Before the 7-hour sleeper break, the driver had 9 hours toward the 14-hour limit, including 4 hours of driving. How many hours does the driver have available (against the 11- and 14-hour limits) after the 7-hour sleeper period?
- The same driver stops for his or her next break after having 4.5 hours against the 14-hour limit, including driving for 4 hours. How long does the break need to be and how many hours does the driver have available when it comes to the 11- and 14-hour limits?
- A driver blew a tire after running over a road hazard. Can this driver use the “adverse driving conditions” exception to make up the two hours that was lost to the repair?
HOS Rules Answers:
- The driver will not have to have a 30-minute interruption in driving until 8:00 p.m. This is when the driver will have accumulated 8 hours of driving since the last interruption in driving of 30 minutes or more.
- Yes, as long as the two activities are consecutive. Under the new rule, the driver must not drive during the 30-minute interruption in driving. Therefore, on-duty time can be counted toward the 30 minutes.
- After the break, the driver has 5 hours until the 14-hour limit is reached (14 - 9 used before the break) and 7 hours of driving before the 11-hour limit is reached (11 - 4 used before the break).
- The next break must be a minimum of 3 hours (10 - 7 hours in the sleeper). After the 3-hour break, the driver will have 9.5 hours until the 14-hour limit is reached (14 – 4.5 used before the break) and 7 before the 11-hour limit is reached (11 – 4 used before the break).
- No. An adverse condition is a road, traffic, or weather condition that could not have been known at time of dispatch and when the driver started his or her day. Breakdowns, operational issues, and customer delays do not qualify as adverse conditions.
