What must drivers do if they unexpectedly fail to meet the requirements of the 150-air-mile-radius exception?

Drivers who normally uses the 150-air-mile-radius exception — which is an exception from needing logs for tracking hours of service — may find that they unexpectedly don’t meet the exception criteria. For example, drivers who travel outside the 150 air-mile radius or who work longer than 14 hours may no longer qualify. If this happens, drivers should fill out a record of duty status for the whole day, beginning as soon as they know they will not qualify, even if it means changes of duty status will have to be recorded retroactively. Drivers also become subject to the requirements for a 30-minute break after 8 hours of driving (for drivers of property-carrying vehicles) and the need to keep supporting documents. Note that drivers may return to using the exception on the following day if the terms of the exception are met.
