How does a driver log daylight savings time?

There are no “official” guidelines for logging when the time changes. What most drivers do is simply drop a line down to the remarks section (on a paper log) or add an annotation (on an ELD) noting the change at 2:00 a.m., such as by writing “Daylight Savings.” It should not affect drivers’ hours because they still must comply with the 10-, 11-, 14- (or 8-, 10-, 15-), and 60/70-hour rules. These rules are not dependent on what the clock reads; rather, they depend on how much time the person actually worked/drove or rested.

While ELDs may handle the time change automatically, drivers using paper logs will need to:

• Leave one hour (2:00 a.m. – 3:00 a.m.) blank on the log when they “lose” the hour in the spring, and
• Add a remark to explain their duty status for the hour they “gain” in the fall (when they repeat the hour from 1:00 a.m. – 2:00 a.m.).
