OPINION
Appellant, Stella Francis (“Francis”) appeals from a take nothing judgment rendered against her and in favor of appellee, Dan Cogdell (“Cogdell”). The judgment is based on a jury verdict failing tо find negligence on the part of Cogdell in rear ending Francis’ vehicle. We affirm.
In her first point of error, Francis makes the general assertion that, “there is a presumption that if you hit someone from the rear, you are the cause of their accident.” Francis has not provided this Court with any authority in support of this proposition, other than references, for the first time on appeal, to Tex.Rev.Civ.Stat.Ann. art. 6701d, § 61 (Vernon 1975). 1 Francis claims that, because of the existence of this presumption, the trial court erred in not granting a directed verdict in her favor. 2
In reviewing the denial of an instructed verdict by the trial court on an evidentiary basis, the reviewing court will determine whether there is any evidence of probative force to raise a fact issue оn the material questions presented.
Collora v. Navarro,
If there is any conflicting evidence of probative vаlue on any theory of recovery, an instructed verdict is improper and the issue must go to the jury.
White v. Southwestern Bell Tel. Co.,
651 S.W.2d
*870
260, 262 (Tex.1982);
Texas Employers Ins. Ass’n v. Page,
The question presented to the jury was, “Did the negligence, if any, of the persons named below [Cogdell and Francis] proximately cause the occurrence in question?” The trial court had before it the following evidence in considering whether to send this question to the jury or grant a direсted verdict:
On March 2, 1988, Francis was approaching the intersection of the 1-10 West feeder road and Durham. She testified that as she approached the intersection, the light was red аnd she had come to a complete stop. She was at the intersection for about 30 seconds, when she was rear-ended by a Suburban truck driven by Cogdell. It had been raining and the traffic was medium. She never saw Cogdell’s vehicle before the impact.
Cogdell testified he first saw Francis’ car several car lengths before the intersection. There were two or three car lеngths between his car and Francis’ car. He said Francis abruptly, and in a dangerous fashion, slammed on her brakes. Cogdell hit his brakes hard, and his car skidded into Francis’ car. He said: “My direction was drawn tо the light after I saw her vehicle, because I was thinking I had a green light, we both had a green light, I was thinking, ‘Why is this woman throwing her brakes on?’ ” Cogdell asserts the manner in which Francis stopped her vehicle cаused him to collide with her vehicle.
A case similar to the one presented here is
Ruffin v. J.W. Weingarten, Inc.,
On appeal, Ruffin madе a similar argument to that advanced here by Francis— that the evidence conclusively established the following driver's negligence and the court should have, as a matter of law, enterеd judgment for her. 3
In affirming judgment for Weingarten’s, the Tyler court found the conflicting evidence presented only a fact question for the jury to resolve.
Ruffin,
The first point of error is overruled.
Francis complains in her second point of error, the trial court erred in instructing the jury regarding an unavoidable accident or sudden emergency. Francis claims there was no evidence or insufficient evidence to support the court giving such an instruction.
In response, Cogdell asserts Francis has not preserved her pоint of error because she is raising a factual insufficiency point and she did not file a motion for new trial. Tex.R.Civ.P. 324(b)(2). Rule 324 provides that a motion for new trial is a prerequisite to making a complaint on appeal if the complaint involves the factual insufficiency of the evidence to support a jury finding. Francis is not complaining of the factual insufficiency to suppоrt a jury finding, but rather, the legal insufficiency of the evidence to support the trial court *871 giving an explanatory instruction. Francis was not required to file a motion for new trial in this situation; Cogdell’s assertion is overruled.
The only function of an explanatory instruction in the court’s charge is to aid and assist the jury in answering the issues submitted.
Atchison, Topeka, and Sante Fe Ry. v. O’Merry,
Cogdell pled the accident was caused by Francis’ negligence, and he specifically requested the court instruct the jury on the doctrines of sudden emergency and unavoidable accident. Cogdell’s pleading was supported by competent evidence. It was uncontroverted the accident occurred during morning “rush hour” and that it had been raining, causing the roads to become wet and slick. Cogdell testified the light was yellow and Francis suddenly slammed on the brakes in a negligent manner, causing him to run into her.
The Fourteenth Court of Appeals was confronted with an analogous situation in
Daggett v. McReynolds,
In
Erickson v. Deayala,
We find Deayala and McReynolds persuasive and adopt their reasoning here. We find the uneontradicted testimony as to the rainy, slick road condition, and Cog-dell’s testimony concerning Francis’ conduct, was some evidence to support the trial court giving the requested instruction.
We note that for the first time, during oral argument, Francis complains of the trial court’s failure to give an instruction concerning a “presumption of negligence” in a rear end collision, or an instruction on negligence per se. She did not assert this argument as a point of error in her brief, nor did she properly request such an instruction at trial. Thus, she has not preserved error concerning this complaint. Tex.R.Civ.P. 278; Tex.R.App.P. 74(d).
Francis’ second point of error is overruled.
The judgment of the trial court is affirmed.
Notes
. Section 61(a) of article 670Id provides that:
The driver of a motor vehicle shall, when following another vehicle, maintain an assured clear distance between the two vehicles, exercising due regard for the speed of such vehicles, traffic upon and conditions of the street or highway, so that such motor vehicle can be safely brought to a stop without colliding with the preceding vеhicle, or veering into other vehicles, objects or persons on or near the street or highway.
. We note here that Francis has not accurately recited the Texas rule on nеgligence in rear end collision cases. The rule in Texas regarding lookout to the rear is that the lead driver has no duty to keep a lookout for traffic approaching from thе rear unless the lead driver changes his lane or direction, stops or suddenly decelerates, in either of which case he has a duty to keep a proper lookout to the rеar and to give a proper signal of his intention.
Burnett v. Howard,
. In Ruffin, the plaintiff had asked for judgment notwithstanding the jury's verdict; here, Francis asked for a directed verdict. Since both ver-diets require a "matter of law” determination, we do not find the distinction to be of any consequence.
