Section 13(b)(11) exempts from the provisions of section 7 of the
Act:
Any employee employed as a driver or driver's helper making local
deliveries, who is compensated for such employment on the basis of trip
rates, or other delivery payment plan, if the Secretary shall find that
such plan has the general purpose and effect of reducing hours worked by
such employees to, or below, the maximum workweek applicable to them
under section 7(a).
This is an exemption from the overtime pay requirements only.
