It also describes HOS regulations in Canada and Mexico, since trucks and buses from these countries routinely enter the United States and vice versa, and HOS regulations in these countries can therefore be compared with those in the United States. BACKGROUND The first HOS regulations for interstate commercial drivers were issued in 1938 by the Interstate Commerce Commission (ICC)

On-Duty Time On-duty time refers to the time during which the driver is working, which encompasses driving, loading, and unloading. The HOS regulations set limits on on-duty and driving time: • On-duty limit refers to the maximum amount of total duty time in a 24-hour duty cycle and a 7-day period that is allowed.

, a driver can use the sleeper berth to rest during the off-duty period. The sleeper berth provi sion under the HOS regulations allows drivers some flexibility in how they utilize their off-duty time.2 In addition, the HOS regulations include a restart provision that requires drivers who drive the maximum number of allowable hours to restart their weekly duty cycle after being off duty for a certain number of hours.

The 2011 rulemaking also rescinded the flexibility to split sleep under the sleeper birth provision so as to discourage drivers from experiencing irregular and shorter periods of sleep. FMCSA indicated that the new rules "moved drivers toward a work-rest schedule that more closely matched the natural circadian cycle of 24 hours and gave drivers the opportunity to obtain the 7 to 8 hours of uninterrupted sleep per day that most adults need," which would be concordant with the discussion of driver fatigue and human physiology in Chapters 1 and 3.

And just as the movement of goods is facilitated by trucks, the mobility of persons is facilitated by bus networks that enable travel for people from the three countries.3 The regulations for Canada and Mexico, as well as Australia and the European Union, are summarized in Table 4-2.
