What role does the “reasonable person” standard play in evaluating negligence claims?
It’s the measuring stick for ordinary negligence. O.C.G.A. § 51-1-2 asks what “ordinarily prudent persons” would do “under the same or similar circumstances.” The jury compares the defendant’s conduct to that hypothetical person. A sincere belief or a good-faith effort doesn’t answer the question, because the test isn’t what this defendant thought.
What the standard takes into account
| Factor | Considered? |
|---|---|
| Circumstances: weather, traffic, emergency | Yes |
| Knowledge available at the time | Yes |
| Defendant's inexperience as a new driver | No lower standard, in general |
| Defendant's physical disability | The circumstances may include it |
| Child's age and capacity | Yes, § 51-1-5 |
| Professional training | Yes, § 51-1-27 applies a higher measure |
| Defendant's personal carelessness or low intelligence | No |
Applied to the plaintiff
The same measure applies to the plaintiff’s own care. O.C.G.A. § 51-11-7 speaks of a plaintiff who “by ordinary care could have avoided the consequences” of the defendant’s negligence, and § 51-12-33 asks whether the plaintiff was responsible. A jury may see the two sides through the same lens.
How jurors use it
A jury doesn’t need an expert to say what a prudent person would do at a stop sign, since that’s within common experience. Jury instructions explain the standard, and lawyers argue what a prudent person would have done on these facts.
Limits
- Professional judgment. A juror’s common sense can’t supply what a surgeon should do. An expert has to establish that.
- Gross negligence. A lower measure, “slight diligence,” under § 51-1-4.
- Extraordinary diligence. Common carriers of passengers owe more (§ 46-9-132).
- Statutes. A safety statute can define the conduct required.
- Duty. The test measures care. It doesn’t decide if a duty existed (CSX Transportation, Inc. v. Williams, 278 Ga. 888 (2005)).
Hindsight
The question is what a prudent person would’ve done at the time, with what could be known then. A jury is told to avoid judging by the result.
At summary judgment
Reasonableness is for the jury, except in plain and undisputed cases. A defendant who claims it acted reasonably, and a plaintiff who claims otherwise, can’t resolve a real dispute on paper.
Example
For example, imagine a driver going the speed limit in heavy rain who hydroplanes. Staying within the limit doesn’t end the question, since a prudent person might slow down in those conditions. A jury could go either way, depending on the visibility, the traffic, and how fast the car was going.
