Charles McBroom entered suit in Whitfield County, Georgia, against Roadway Express Inc.,' and its indemnity-insurance carrier because of the alleged negligence of the agent and driver of the truck of Roadway Express Inc., one Walker, who, it is alleged, negligently drove the truck of Roadway Express Inc., into a truck being driven by the plaintiff 'and thereby caused certain personal injuries. In addition to its answer the defendant filed a plea of former adjudication in which it was alleged that Walker, the driver and agent of Roadway Express Inc., whose alleged negligence is the basis of the plaintiff’s action here, had, as a result of the collision of the said trucks, filed suit in Tennessee against the plaintiff in a named court of competent jurisdiction to recover for injuries that he, Walker, had-sustained in damages to his truck, it being the same truck, growing out of the same transaction or collision referred to in the present action, and that in that suit the plaintiff here was the defendant, and Walker had recovered against him a judgment, which had been affirmed by a reviewing court in Tennessee, and that such judgment settled “all issues as between the parties to this case.” This amendment, was allowed, but on the trial of the case the trial judge sustained a motion to strike such amendment. The defendant excepted pendente lite to such ruling, and as this question is determinative of the action we will consider it first.
We may say in the beginning that under the full faith and credit clause of the constitution (Code, § 1-401;
McHenry v. McHenry,

The Supreme Court in the case of Smith v. Gettinger, 3 Ga. 140, 142, has given the following definition of a privy: “Privies are all persons who are represented by the parties and claim under them, all who are in privity with the parties; the term privity denoting mutual or successive relationship to the same rights of property.” We quote further: “This rule is founded upon the expediency and necessity that a limit should be prescribed to litigation, and that the same cause of action ought not to be brought twice to a final determination. ‘Justice requires (says Mr. Green-leaf) that every cause be once fairly and impartially tried; but the public tranquillity demands, that having been once so tried, all litigation of that question and between those parties should be closed *226 forever.’ Persons occupying the relation of privies are concluded by the judgment, on the ground that they are identified in interest with the party.”
The question as applied to facts such as are alleged in the present ease has never been decided in Georgia so far as we have been able to discover. It has been repeatedly held that a verdict exonerating the servant in a joint action brought against the master and the servant for damages caused solely by the negligence of the servant requires a verdict for tire master also.

Under the állegations of the petition in this case the negligence of Roadway Express Inc. was derivative from the negligence of Walker, its agent and driver at the time, and its responsibility for such negligence is by reason of the doctrine of respondeat superior. In Good Health Dairy Products Cor.
v.
Emery,
*227 The rule is well stated in 1 Freeman on Judgments, 5 ed., 1031, ■§ 469, as follows: “The rule is general and well settled that where the liability, if any, of a principal or master to a third person is purely derivative and dependent entirely on the principle of respondeat superior, a judgment on the merits in favor of the agent or servant, or even a judgment against him, in so far as it fixes the maximum limit of liability, is res judicata in favor of the principal or master though he was not a party to the action. This rule is only an exemplification of the broader rule by which one whose liability is wholly derivative may claim the benefit of a judgment in favor of the person from whom his liability is derived, if not based on grounds applicable only to the latter.” We think the provision of the Code that a judgment is conclusive as to the parties and their privies, together with the rule applicable where a master is liable solely under the principle of respondeat superior, give to such master the right to plead, as res judicata, a judgment rendered in favor of such servant or employee, when the identical negligence in the transaction is the subject-matter of the suit on which the judgment in favor of the servant is predicated.
It is insisted, however, that the plea of res judicata in this case failed to have attached thereto an exemplification of the proceedings which are alleged to have been based on the same cause of action between the parties, and that for this reason the court correctly struck the plea. W'hen the plea was offered it was ordered filed without objection. On the trial an oral motion to strike the plea was offered and sustained, and exception to this ruling was preserved pendente lite. A motion to strike is nothing more than a general demurrer. It does not take the place of a special demurrer. The plea alleged that the plaintiff ought not to recover for the reason that on August 18, 1937, W. E. Walker, who in the petition is alleged to have been the driver of the 'truck and the employee of the defendant, filed his suit in a named court in Tennessee against the named plaintiff to recover damages sustained by said Walker, growing out of the same transaction referred to in said petition and the same automobile truck, and that said action resulted in a verdict in favor of Walker which has been affirmed by the appellate court, and that the result of that suit adjudicated all issues between the parties to the present action. There was no demurrer raising the question as to the sufficiency of the allegation, *228 because no exemplification of the record of such proceedings in the Tennessee court was attached, nor was the defendant allowed to amend by attaching such record.

The test of the sufficiency of a plea to resist a general demurrer or motion to strike is, may the plaintiff admit all that is contained or alleged therein and yet be entitled to recover? In
Jones
v.
Lavender,
55
Ga.
228 (2), it is said: “The record of a former recovery is admissible under a special plea (however vague) setting up a former suit,
unless objected to on account of insufficiency in the plea.”
(Italics ours.) A plea of res judicata which alleges that the same issues between the same parties or their privies have been adjudicated in a court of competent jurisdiction is sufficient as against a motion to strike, however subject it may be to a special demurrer. See

*230 The court having stricken this plea and thus withdrawn the issues attempted to be made by such plea, and this ruling having been erroneous, it becomes unnecessary to determine the issues made upon the trial, for if the defendant is able upon trial to prove the allegations of his plea of former adjudication no other trial will be necessary.
Judgment reversed.
