Final answer:
Professional drivers are often required to take a mandatory rest period after 14 days of driving to prevent fatigue and ensure safety, with the duration varying by local regulations, such as a 34-hour rest period in some cases.
Step-by-step explanation:
When considering how many hours a driver must take off after 14 days, it's important to adhere to health and safety regulations that often dictate mandatory rest periods for professional drivers to prevent fatigue-related accidents. The specific duration of the required rest can vary depending on the country and the specific regulations in place. However, it is generally recognized that drivers should take significant uninterrupted rest after two weeks of work to ensure they are adequately rested before resuming driving duties. For instance, in some jurisdictions, commercial vehicle drivers may be required to take at least 34 consecutive hours off after 14 consecutive days of driving to reset their driving hours limit.
