Common Defenses in Georgia Car Accident Cases

A defendant in a Georgia car-accident case rarely concedes liability outright. Instead, the defense raises one or more recognized doctrines that reduce or eliminate a plaintiff’s recovery, shift a share of fault, or attack the timeliness of the claim. This guide catalogs the defenses most frequently asserted in Georgia auto litigation, identifies the legal basis of each, describes the evidence typically marshaled to support it, and notes how each is commonly met. The doctrines apply differently to different facts, so the descriptions below are general rather than predictive of any particular case.

Comparative Negligence

The most common defense argues that the plaintiff was partly responsible for the collision or for the severity of the injuries. Under Georgia’s modified comparative-negligence rule, OCGA 51-12-33, any fault assigned to the plaintiff reduces recovery proportionally, and recovery is barred entirely when the plaintiff is found 50 percent or more at fault. The bar operates at 50 percent or more, not at “more than 50 percent.” A defendant typically offers evidence of the plaintiff’s speed, distraction, lane position, failure to brake, or, in qualifying cases, non-use of a seatbelt. Objective proof of the plaintiff’s reasonable conduct and the defendant’s breach, such as dashcam footage, witness testimony, event-data-recorder readings, and reconstruction analysis, is generally used to keep the plaintiff’s share low. The full mechanics of apportionment are addressed in the discussion of Georgia comparative negligence.

Seatbelt Defense After SB 68

For many years Georgia barred evidence of seatbelt non-use. SB 68, signed and effective April 21, 2025, changed that result through the amended seatbelt-admissibility provision, OCGA 40-8-76.1. For actions commenced on or after April 21, 2025, a defendant may introduce evidence that an adult plaintiff was not wearing a seatbelt, and the evidence may bear on negligence, causation, comparative fault, and apportionment. The trigger is the filing date of the action, not the date of the collision, and that “actions commenced” framing is the correct reading of the statute. The adult-belt statute is OCGA 40-8-76.1; the separate child-restraint statute is OCGA 40-8-76 and should not be conflated with it. This defense is commonly met with biomechanical testimony that the specific injuries would have occurred regardless of belt use, challenges to the reliability of the seatbelt evidence itself, and, where applicable, evidence of a defective restraint. A fuller treatment appears in the discussion of the Georgia seatbelt defense.

Pre-Existing Condition

Here the defense contends that the claimed injuries predated the collision and are wrongly attributed to it. Georgia’s eggshell-plaintiff rule is the principal answer. That rule is a matter of Georgia common law, not a codified statute, and Georgia courts have long held that a tortfeasor takes the victim as found; a negligent defendant bears the risk that the victim’s actual physical condition increases the harm. The rule was applied in AT Systems Southeast, Inc. v. Carnes, 272 Ga. App. 671 (2005), where complications flowing from the plaintiff’s pre-existing health conditions did not reduce the defendant’s liability. Because the eggshell rule rests in case law rather than in OCGA 51-12-8, it is properly described as a common-law doctrine. The defense is commonly met with before-and-after medical records establishing the baseline and the post-collision change, treating-physician testimony explaining the mechanism of aggravation, and imaging showing new pathology.

Assumption of Risk

This defense argues that the plaintiff knowingly and voluntarily accepted the specific risk that caused the injury. In auto cases the doctrine is narrow. Its strongest application is a passenger who voluntarily rode with a driver known to be intoxicated. The defense requires actual knowledge of the particular risk and voluntary acceptance of it; a passenger who did not know the driver was impaired generally has not assumed that risk, and the general awareness that driving carries some danger does not amount to assumption of risk for a specific crash.

Sudden Emergency

The sudden-emergency doctrine asserts that the defendant’s conduct was excused by an unexpected emergency not of the defendant’s own making, such as a deer entering the roadway, a child darting into traffic, an abrupt mechanical failure, or a medical event like a seizure. The emergency must be genuinely unforeseen, and the defendant must not have created the conditions that made it dangerous. A driver who was speeding when a hazard appeared generally cannot invoke the doctrine if the hazard could have been avoided at a lawful speed, and a driver who ignored warning signs of failing brakes generally cannot claim the failure was unforeseeable.

Low-Impact Defense

This defense contends that the collision forces were too low to cause the claimed injuries, relying on photographs of minor vehicle damage and the inference that low property damage means low occupant injury. It is commonly met with biomechanical testimony explaining that vehicle-damage severity and occupant-injury severity are different measurements, that modern crumple zones absorb energy through controlled deformation so a vehicle may show little damage while transmitting substantial force, and that occupant variables such as body position, age, and pre-existing vulnerability affect injury independently of visible damage.

Failure to Mitigate

A defendant may argue that the plaintiff failed to take reasonable steps to limit the harm after the collision, such as missing medical appointments, declining recommended treatment, returning to activity too soon, or not following physician instructions. The response generally documents consistent treatment, explains any gaps with reasons reflected in the record, and shows adherence to medical advice.

Statute of Limitations

The defense argues the claim was filed too late. Under OCGA 9-3-33, the personal-injury limitation period is two years from the date of the collision, and an untimely claim is generally barred regardless of its merits. Recognized tolling doctrines may apply, including tolling during minority under OCGA 9-3-90 and tolling for a defendant’s absence from the jurisdiction under OCGA 9-3-94, and the availability of any tolling depends on the specific facts. The broader limitation framework, including how the period accrues and when it may be extended, is addressed in the discussion of the Georgia car-accident statute of limitations.

Illustrative Apportionment Figures

The following figures are illustrative only and do not reflect any actual case or predicted result; they show how the comparative-fault math operates under OCGA 51-12-33.

• Assumed total damages found by the trier of fact: $100,000.
• Plaintiff found 20 percent at fault: recovery reduced by $20,000 to $80,000.
• Plaintiff found 49 percent at fault: recovery reduced to $51,000.
• Plaintiff found 50 percent at fault: recovery barred entirely, because the bar operates at 50 percent or more.

The illustration shows only the mechanics of proportional reduction and the 50-percent cutoff, not any prediction about how fault would be assigned in a real case.

Frequently Asked Questions

What happens to recovery if a Georgia plaintiff is partly at fault?
Under OCGA 51-12-33, recovery is reduced in proportion to the plaintiff’s share of fault and is eliminated entirely if the plaintiff is found 50 percent or more responsible.

Can seatbelt non-use be used against a plaintiff in Georgia now?
For actions commenced on or after April 21, 2025, yes. Under the amended OCGA 40-8-76.1, evidence that an adult was unbelted may be admitted on negligence, causation, comparative fault, and apportionment. The trigger is the filing date of the action.

Does a pre-existing condition defeat a Georgia injury claim?
Generally not by itself. Under Georgia’s common-law eggshell-plaintiff rule, illustrated by AT Systems Southeast, Inc. v. Carnes, a defendant takes the plaintiff as found and bears the risk that a pre-existing condition worsens the harm.

How long does a plaintiff have to file a Georgia car-accident claim?
Two years from the collision for personal injury under OCGA 9-3-33, subject to recognized tolling doctrines such as minority under OCGA 9-3-90 and a defendant’s absence under OCGA 9-3-94.
