Whatever cycle you are driving on, you must not drive unless you have had at least 24 consecutive off-duty hours at some point in the preceding...?

The requirement for having at least 24 consecutive off-duty hours at some point in the preceding 14 days is based on regulations designed to ensure that drivers, particularly those operating commercial vehicles, have adequate rest to maintain safety on the road. This rule helps prevent fatigue, which can significantly impair judgment and reaction times, thereby increasing the risk of accidents.

By enforcing this 14-day off-duty period, the regulation supports the health and well-being of drivers, promoting safer driving conditions. It acknowledges that proper rest is essential for drivers who often work extended hours and might face demanding schedules. Having this rest period ensures that they are adequately refreshed and alert before getting back on the road, leading to safer outcomes for all road users.

The other options do not meet the regulatory requirements as effectively as the 14-day period does, as longer intervals may not adequately address the immediate needs for rest and recovery that drivers often require.
