WILLIAM MONTANA APPELLANT,

v.

WILFOR GORP AND BONNA GORP, CO-PARTNERS, D/B/A VAN GORP VAN SERVICE, APPELLEES

CARROLL, CHAS., Chief Judge.

This appeal, by plaintiff below, is from a summary judgment for defendants in an action for damages for personal injuries.

From the pleadings, admissions, answers to interrogatories and an affidavit, the court had before it the followings facts.

Defendants, carriers, were transporting certain race horses by a semi-trailer van driven by their employee. The plaintiff was a passenger in the capacity of a groom or attendant, hired by the horse owner to care for the horses, and his presence there was required by the defendants.1

The plaintiff charged the defendants with negligence in two respects. He alleged that the truck was swerved suddenly across the road with the result that the door came open and he was thrown through the door onto the road. He also alleged that the latch on the door was defective or was improperly secured, with the result that the door opened and he fell through. Plaintiff’s affidavit supplemented those allegations. He said that while the truck was in motion, it suddenly swerved across the road, causing the door of the trailer to open and throwing him, from a standing posiiton near the middle of the van, out through the open door to the road. The defendants’ answer denied the allegations of negligence, and included a plea or defense of contributory negligence. In answers to requests for admissions and to interrogatories defendants denied that the door lock was defective; denied that the driver swerved the truck; and maintained that he drove it in a straight and careful manner.

*66With those substantial and material issues established, relating to simple negligence, the court granted the defendants’ motion for summary judgment, on the ground that the evidence did not meet the gross negligence standard required for recovery by a guest passenger under the guest statute. § 320.59, Fla.Stat., F.S.A.2

In holding that the groom who was riding in the truck as an attendant to care for the horses was in the status of a guest passenger who could recover only for gross negligence, the learned trial judge was in error. The guest statute was not applicable on these facts.

One who is a passenger for the mutual benefit of himself and the owner or operator of the vehicle through the negligent use of which he is injured, is not a guest passenger under the statute. Sproule v. Nelson, Fla.1955, 81 So.2d 478; Sullivan v. Stock, Fla.App.1957, 98 So.2d 507; Miller v. Morse Auto Rentals, Fla.App.1958, 106 So.2d 204. That principle has been applied to attendants who were transported by a carrier without charge as necessary to assist in the transportation of freight or animals. Lerma v. Flores, 16 Cal.App.2d 128, 60 P.2d 546; Rogers v. Price, 117 Kan. 181, 230 P. 1047; Nichols v. Rougeau, 284 Mass, 371, 187 N.E. 710; Hansen v. Lawrence, 149 Neb. 26, 30 N.W.2d 63; Russell v. Pilger, 113 Vt. 537, 37 A.2d 403. See Miller v. Miller, 395 Ill. 273, 69 N.E.2d 878; and Annotation, 59 A.L.R.2d 336, 353-356, 357-359.3 Such an attendant or groom is acting in the mutual interest of himself, if he is the owner of the cargo, or of himself and his employer who owns it, and also in the interest of the carrier who either requires such a groom to be supplied by the owner or otherwise must furnish an attendant to care for such cargo.

The carrier in this case recognized the need to have the horses attended en route, and required that the owner have an attendant for that purpose. That the attendant’s presence on the journey was of mutual benefit to the owner of the horses, to himself as the owner’s agent and employee, and to the carrier alike, is plain.

Appended to the bill of lading or contract between the carrier and the shipper there was an “Attendants’ Contract” which is set out in the margin.4 Appellees, in their brief, argue that this “Attendants’ Contract” shows the presence of the attendant was solely in the interest of the shipper and was in no wise for the benefit or in the in*67terest of the carrier. We are unable to read such meaning into the agreement in question.

The facts of this case bring it within the mutual benefit rule thus declared in Sproule v. Nelson, supra; Sullivan v. Stock, supra; and Miller v. Morse Auto Rentals, supra.5

The judgment appealed from is reversed and the cause remanded for further proceedings not inconsistent with this opinion.

Reversed and remanded.
