This reference page catalogs the defenses most frequently raised in Georgia car accident litigation. Each defense is explained with its legal basis, the evidence required to support it, and the strategies available to counter it.
Comparative Negligence
The most common defense. The defendant argues the plaintiff was partially at fault for the accident or for the severity of their injuries. Under O.C.G.A. § 51-12-33, any fault assigned to the plaintiff reduces recovery proportionally, and recovery is eliminated entirely at 50% or more. The defense presents evidence of the plaintiff’s speed, distraction, lane position, failure to brake, or failure to wear a seatbelt (post-SB 68). Counter: objective evidence establishing the plaintiff’s reasonable conduct and the defendant’s breach, including dashcam footage, witness testimony, EDR data, and accident reconstruction analysis. For the full comparative fault mechanism, see Georgia Comparative Negligence.
Seatbelt Defense (Post-SB 68)
For actions commenced on or after April 21, 2025, the defense can introduce evidence that the plaintiff was not wearing a seatbelt under the amended O.C.G.A. § 40-8-76.1. The evidence is admissible on comparative fault (increasing the plaintiff’s fault percentage) and causation (arguing injuries would have been less severe with a belt). Counter: biomechanical expert testimony that the specific injuries would have occurred regardless of seatbelt use, challenges to the reliability of the seatbelt evidence itself (EDR data interpretation, officer observation timing), and if applicable, evidence that the seatbelt mechanism was defective. For the full analysis, see The Seatbelt Defense in Georgia Car Accident Cases.
Pre-Existing Condition
The defense argues that the plaintiff’s injuries predated the accident and are being attributed to the collision. Counter: Georgia’s eggshell plaintiff rule under O.C.G.A. § 51-12-8 requires the defendant to take the plaintiff as they find them. Before-and-after medical records documenting the baseline condition and the post-accident change, treating physician testimony explaining the medical mechanism of aggravation, and diagnostic imaging showing new pathology after the accident all address this defense. For the full analysis, see Pre-Existing Conditions.
Assumption of Risk
The defense argues the plaintiff knowingly and voluntarily assumed the risk that caused the injury. In car accident cases, this defense is narrow. The strongest application is a plaintiff who voluntarily rode with a driver they knew was intoxicated. Counter: assumption of risk requires actual knowledge of the specific risk and voluntary acceptance. A passenger who did not know the driver was impaired cannot have assumed the risk. General awareness that driving involves risk does not constitute assumption of risk for a specific accident.
Sudden Emergency
The defense argues their conduct was excused by an unexpected emergency not of their own making. A deer entering the roadway, a child running into traffic, a sudden mechanical failure, or a medical emergency (seizure, heart attack) may qualify. Counter: the emergency must be genuinely unforeseen, and the defendant must not have created the conditions that made the emergency dangerous. A driver who was speeding when a deer appeared cannot claim sudden emergency if, at the legal speed, they could have stopped or swerved safely. A driver who ignored warning signs of brake failure for weeks cannot claim the failure was unforeseeable.
Low-Impact Defense
The defense argues the collision forces were too low to cause the claimed injuries. This defense relies on photographs of minimal vehicle damage and the argument that low property damage equals low occupant injury. Counter: biomechanical expert testimony establishing that vehicle damage severity and occupant injury severity are fundamentally different measurements. Modern vehicles are engineered to absorb impact energy through controlled deformation of crumple zones, which means the vehicle may show minimal damage while transmitting substantial forces to occupants. Additionally, occupant variables (body position, age, pre-existing vulnerability) affect injury independently of vehicle damage.
Failure to Mitigate
The defense argues the plaintiff failed to take reasonable steps to minimize damages after the accident: missed medical appointments, refused recommended treatment, returned to activities too soon and aggravated the injury, or failed to follow physician instructions. Counter: documentation of consistent treatment compliance, explanations for any gaps (work obligations, financial constraints, childcare responsibilities documented in the medical record), and evidence that the plaintiff followed medical advice.
Statute of Limitations
The defense argues the claim was filed too late. Under O.C.G.A. § 9-3-33, the deadline for personal injury is two years from the date of the accident. If the deadline has passed, this defense is typically dispositive: the claim is barred regardless of its merits. Counter: tolling arguments where applicable (minority under O.C.G.A. § 9-3-90, mental incapacity, defendant absence from jurisdiction under O.C.G.A. § 9-3-94). For tolling rules, see Georgia Car Accident Statute of Limitations.
This guide covers common defenses in Georgia car accident cases as of March 2026. Comparative fault is governed by O.C.G.A. § 51-12-33. The seatbelt defense is governed by the amended O.C.G.A. § 40-8-76.1 (SB 68). Laws change. This information is educational and does not constitute legal advice. If you need advice about your specific situation, consult a licensed Georgia attorney.
