James Kevin Cissell, administrator of the estate of Carla T. Cissell (Cissell), appeals from a jury verdict in favor of Robert Glover (Glover) and Glover Landscape Supply Company (G.L.S.C.).
On 20 February 1994 at approximately 7:45 a.m. Glover, an employee of G.L.S.C., was driving a dump truck (approximately twenty-three feet long and eight feet wide) which pulled a flatbed trailer (approximately thirty feet long and eight feet wide) owned by G.L.S.C., along a rural two-lane paved road known as Emergency Road in a westerly direction. Glover stopped the truck and trailer (after turning around to head in an easterly direction) at a location where the road widened to approximately thirty-six feet and pulled onto the right side of the road for the purpose of loading a large piece of equipment. The truck and trailer were parked on the pavement although other parking locations were available off the pavement. Glover testified that vehicles continued to pass in both directions unobstructed by the truck and that it was not uncommon for other vehicles to park on the paved portion of the road in this area. At approximately 8:00 a.m. Cissell was driving in an easterly direction on Emergency Road when her vehicle struck the rear of the flatbed trailer, directing the car underneath the flatbed trailer. Cissell was killed in the collision. Although Glover testified that he had placed *669three cones and put on the track’s flashers when he first exited the track, Officer M. L. Perry (Perry) of the Henderson Police Department, who arrived at the scene approximately five minutes after the accident occurred, testified that he did not find any traffic cones or flashing lights or other warning devices. Perry also testified that the sun in the direction the plaintiff was driving was blinding. Two other officers who arrived at the scene testified that the sun played a role in causing the accident as it could have obstructed Cissell’s view.
At the close of the evidence Cissell requested the trial court to instruct the jury on the issue of Glover’s gross negligence. This request was denied by the trial court. The trial judge instructed the jury on the issue of negligence, contributory negligence, and damages. The jury returned a verdict answering in the affirmative that Cissell was “injured by the negligence of [Glover],” and also answering in the affirmative that “Cissell by her own negligence [did] contribute to her injury.”
The issue is whether the evidence supported an instruction to the jury on gross negligence.
Contributory negligence will not bar a plaintiff’s recovery where the defendant’s wilful and/or wanton conduct is a proximate cause of the plaintiff’s injuries.; Brewer v. Harris, 279 N.C. 288, 297, 182 S.E.2d 345, 350 (1971); Siders v. Gibbs, 39 N.C. App. 183, 185, 249 S.E.2d 858, 859 (1978); Jarvis v. Sanders, 34 N.C. App. 283, 285, 237 S.E.2d 865, 866 (1977). Wilful or wanton conduct in the context of the contributory negligence issue has sometimes been referred to as gross negligence, Jarvis, 34 N.C. App. at 285, 237 S.E.2d at 866; Bullins v. Schmidt, 322 N.C. 580, 582, 369 S.E.2d 601, 603 (1988), but the use of that term cannot be read to describe conduct less negligent than that suggested by the phrase “wilful or wanton conduct.”1 *670Indeed it is only where the term “gross negligence” is defined to “refer to misconduct which is . . . described as wilful, wanton or reckless . . . [that] the contributory negligence of the plaintiff is not a bar to recovery for an injury caused by such conduct on the part of the defendant.” Stuart M. Speiser et al., The American Law of Torts § 12.11 (1986).
A wilful act “involves a deliberate purpose not to discharge some duty necessary to the safety of the person or property of another.”2 Brewer, 279 N.C. at 297, 182 S.E.2d at 350. “An act is wanton when it is done of wicked purpose, or when done needlessly, manifesting a reckless indifference to the rights of others.” Id. In more general terms, wilful and/or wanton conduct “lies somewhere between ordinary negligence and intentional conduct” and describes “negligence of an aggravated nature.” Siders, 39 N.C. App. at 186, 249 S.E.2d at 860.
The issue of gross negligence should be submitted to the jury if there is substantial evidence of the defendant’s wanton and/or wilful conduct. See Banks v. McGee, 124 N.C. App. 32, 34, 475 S.E.2d 733, 734 (1996) (instruction required if there is substantial evidence as to each element of claim). “Substantial evidence is such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” State v. Smith, 300 N.C. 71, 78, 265 S.E.2d 164, 169 (1980).
In this case, there is ample evidence from which a reasonable mind might conclude that Glover, in the parking of his truck on the paved portion of Emergency Road, demonstrated a reckless indifference to the rights of other persons traveling on that road. A jury could conclude that even if there was enough space for Cissell to pass to the left of the truck, without entering into the other lane of traffic (an issue in itself), the mere parking of the track and trailer on the paved portion of the two-lane road was wanton conduct, especially if the jury were to determine that Glover did not warn oncoming traffic of *671the presence of the truck and trailer by the use of cones, flashers, or other warning devices. Accordingly, the trial court erred in not submitting the issue of Glover’s wilful and/or wanton conduct (gross negligence) to the jury and a new trial is required.
Judge JOHN dissents with separate opinion.
Judge WALKER concurs.
