The DOT Interpretations - 395.2 (from the big book) says: Question 5: Do telephone calls to or from the motor carrier that momentarily interrupt a driver's rest period constitute a change of the driver's duty status? Guidance: Telepphone calls of this type do not prevent the driver from obtaining adequate rest. Therefore, the FHWA does not consider these brief telephone calls to be a break in the driver's off-duty status. Question 30: If a driver is required repeatedly to respond to satellite or similar communications received during his or her sleeper berth period, does this activity affect a driver's duty status? Guidance: Yes. The driver cannot be required to do any work for the motor carrier during sleeper berth time. A driver who is required to access a communications system for the purpose of reading messages from the carrier, responding to certain messages (either verbally or by typing a mesage), or otherwise acknowledging them, is performing work. For the purpose of this guidance, "repeatedly" means a pattern or series of interruptions that prevent a driver from obrtaining restorative sleep during the sleeper berth period. |
