§ 541.504 Drivers who sell.
(a) Drivers who deliver products and also sell such products may qualify as exempt outside sales employees only if the employee has a primary duty of making sales. In determining the primary duty of drivers who sell, work performed incidental to and in conjunction with the employee's own outside sales or solicitations, including loading, driving or delivering products, shall be regarded as exempt outside sales work.
(b) Several factors should be considered in determining if a driver has a primary duty of making sales, including, but not limited to: a comparison of the driver's duties with those of other employees engaged as truck drivers and as salespersons; possession of a selling or solicitor's license when such license is required by law or ordinances; presence or absence of customary or contractual arrangements concerning amounts of products to be delivered; description of the employee's occupation in collective bargaining agreements; the employer's specifications as to qualifications for hiring; sales training; attendance at sales conferences; method of payment; and proportion of earnings directly attributable to sales.
