A property-carrying commercial motor vehicle driver begins a shift at 08:00 after completing a qualifying 10-hour off-duty period. The driver performs on-duty pre-trip and loading duties from 08:00 to 11:00, drives continuously from 11:00 to 16:00, and then takes an off-duty meal break from 16:00 to 17:00. Assuming standard property-carrying rules and normal conditions without split sleeper berth use, what is the maximum number of additional hours the driver is legally permitted to drive before the shift must end?

  1. A
    4 hours
  2. 5 hoursCevap
  3. C
    6 hours
  4. D
    7 hours

Cevap

5 hours
The 14-hour duty window began at 08:00 and expires at 22:00. At 17:00, there are exactly 5 hours left before 22:00. Although the driver has only driven 5 hours (which leaves 6 hours of available driving under the 11-hour limit), no driving is permitted past the 14-hour mark. Therefore, the driver is restricted to a maximum of 5 additional driving hours.

Adım Adım Çözüm

1
Determine the hard cutoff of the 14-hour consecutive duty window.
The 14-hour window begins at 08:00 and ends strictly at 22:00.
Under FMCSR, a property-carrying driver cannot drive after the 14th consecutive hour coming on duty, and off-duty breaks do not pause this clock.
2
Calculate the available driving hours remaining under the 11-hour driving limit.
6 hours remaining under the driving limit (11 hours maximum - 5 hours already driven).
A driver is permitted a total of 11 hours of driving within a shift following 10 consecutive hours off duty.
3
Calculate the remaining window time from the end of the break to the 14-hour cutoff.
5 hours remaining in the window (22:00 cutoff - 17:00 current time).
The driver is ready to drive at 17:00, leaving exactly 5 hours before reaching the 22:00 cutoff.
4
Compare both constraints to find the governing maximum driving limit.
5 hours maximum.
The driver is constrained by the more restrictive limit (5 hours left in the 14-hour window vs. 6 hours left in the 11-hour driving bank).
