Hours of Service

10 Hour Rule

A 10 hour break is defined as any one of the following:

Off Duty

  • (a minimum of) 10 Hours continuously OFF DUTY (Line 1)

Sleeper Berth

  • (a minimum of) 10 Hours continuously in SLEEPER BERTH (Line 2)


  • (a minimum of) 10 Hours continuous any combination of OFF DUTY (Line 1) and SLEEPER BERTH (Line 2)

Split Sleeper Berth

  • See explanation below, however Knight prefers drivers not utilize the split sleeper rule.

11 Hour Rule

You may not DRIVE more than 11 hours since your last 10 hour break.

14 Hour Rule

You may not DRIVE past the 14th hour since the end of your last 10 hour break.

70 Hour Rule

You may not DRIVE after having been ON DUTY more than 70 hours in the last 8 days.

For purposes of this rule, ON DUTY is the total of any time DRIVING (Line 3) or ON DUTY NOT DRIVING (Line 4).

30 Minute Rule

You may not DRIVE if more than 8 hours have passed since the end of your last off-duty or sleeper berth period of at least 30 minutes.

34 Hour Restart

After 34 hours consecutive OFF DUTY (including SLEEPER BERTH) you have 70 hours available again.

You may count as 0 the hours worked in the last 7 days.

Split Sleeper Berth Rule.

You may split your 10 hour break into two periods.

One of the periods must be at least 8 hours (but less than 10) continuous in the SLEEPER BERTH.

The other  period must be at least 2 hours in the SLEEPER BERTH or OFF DUTY or any combination of the two.

(Any SLEEPER BERTH  period lasting between 8 and 10 hours halts the 14 hour rule.)

After you have fulfilled both an 8 and a 2 hour period, your 11 and 14 hour clocks are reset to the end of the first of the two periods.


Two adjacent periods, one 8-10 Hours in the SLEEPER BERTH, and one 2 or more hours either SLEEPER BERTH or OFF DUTY (or any combination of the two).

Any two adjacent periods driving may not total more than 11 hours.

Any two adjacent periods on duty may not total more than 14 hours.
