If another driver hurt you in a Maine crash, one of the first things the insurer will raise is how much of the wreck was your fault. Maine's answer to that question is set by statute, and it is stricter than the rule a lot of people assume applies. The number that matters is 50 percent, and landing exactly on it costs you everything.
The 50 percent bar, and why "equally at fault" means zero
Maine uses modified comparative negligence. You can still recover money after a crash you partly caused, but only if your share of the fault stays below the other side's. The controlling statute, 14 M.R.S. Section 156, says a claim "may not be defeated by reason of the fault of the person suffering the damage," then adds a hard cutoff: "If such claimant is found by the jury to be equally at fault, the claimant may not recover."1
Read that line carefully. "Equally at fault" is 50/50. In Maine, a driver found exactly half responsible for a collision takes home nothing.1 That is the split between Maine and the more common "51 percent" version of the rule, where a plaintiff who is exactly 50 percent at fault can still collect half. Here, 50 is the wall, not 49. So the practical goal in any disputed Maine case is keeping your share under half.
How a Maine jury actually cuts the award
Most comparative-fault states run a simple formula: the jury assigns you a percentage, and the court multiplies the damages by the rest. Maine does not work that way, and the difference is written into the statute.
Section 156 tells the court to instruct the jury to first "find and record the total damages that would have been recoverable if the claimant had not been at fault," and then to "reduce the total damages by dollars and cents, and not by percentage, to the extent considered just and equitable, having regard to the claimant's share in the responsibility."1 The jury records both figures, and the lower one is the verdict.1
That "just and equitable" language gives a Maine jury more room than a strict percentage would. A jury that finds you mostly blameless can shave only a little off a large award, and one that is less sympathetic has room to cut more, so long as your share does not cross the 50 percent line that bars recovery altogether.1 It also means how your conduct gets explained to a jury can move the final number in a way a fixed math operation never could.
What counts as "fault"
The statute defines fault broadly. Under Section 156, "fault" means "negligence, breach of statutory duty or other act or omission that gives rise to a liability in tort."1 Speeding, following too closely, driving distracted, or blowing through a traffic control can all be weighed against you, and so can conduct that is not classic bad driving, as long as it fed into the crash.
There is a limit the Maine Law Court has drawn. Comparative fault reduces damages in negligence cases, but it is not a defense to an intentional tort. In McLain v. Training and Development Corp., 572 A.2d 494 (Me. 1990), the court refused to cut a damages award for the plaintiff's own conduct where the defendant was liable for assault and battery, holding that it had never recognized comparative negligence as a defense to an intentional tort and declining to start.2 That matters for crashes caused by deliberate acts, such as road rage, where a defendant cannot chip away at the award by pointing to the victim's ordinary carelessness.
When more than one driver is to blame
Maine keeps joint and several liability. In a case with multiple defendants, "each defendant is jointly and severally liable to the plaintiff for the full amount of the plaintiff's damages," which means you can collect the whole judgment from any one of them even if others were more at fault or cannot pay.1 A defendant who wants the jury to sort out each party's share can ask for special interrogatories on "the percentage of fault contributed by each defendant."1
Your own fault is measured against the defendants' combined fault, not against each one on its own.1 If two other drivers share the blame for hitting you and you were 40 percent responsible, you are under the 50 percent bar and can recover, reduced for your share, even though your 40 percent is larger than either driver's individual slice.
How the fault rule fits the rest of a Maine claim
Comparative negligence decides how much you collect. Several other Maine rules decide whether and when you can bring the claim at all.
Maine is an at-fault, or tort, state for auto insurance, so the driver responsible for the crash and that driver's insurer pay for the harm.3 There is no true no-fault PIP system here. Every standard Maine auto policy has to carry at least $2,000 in medical payments coverage for costs incurred within a year of the crash, and that coverage cannot be rejected.4 Minimum liability limits are 50/100/25: $50,000 per person and $100,000 per crash for bodily injury, plus $25,000 for property damage.5 Maine also requires uninsured and underinsured motorist coverage equal to your liability limits unless you sign a written rejection, and even then it cannot drop below 50/100.6
The timing is generous by comparison to most states. Maine gives you six years to sue for a negligence injury under 14 M.R.S. Section 752, and the same six-year period covers vehicle property damage.7 As long as that window is, proof of who was at fault fades fast, so the official police crash report is worth getting early. You can order a report through the Maine crash report page.
The fault rule reaches property claims too. Because Section 156 reduces recovery for "damage," not just injury, your share of the blame trims a vehicle-damage or diminished value claim the same way it trims an injury award.1
It carries into fatal crashes as well. Maine's wrongful death statute lets a family recover, but caps damages for loss of comfort, society, and companionship at $1,000,000 (adjusted for inflation) and punitive damages at $500,000, under 18-C M.R.S. Section 2-807.8 Section 156 applies to "death or damage," so a comparative-fault reduction can apply to a wrongful death recovery too.1
What this means if you were partly at fault
Being partly at fault does not end a Maine claim. Being half at fault does. And because the jury sets the reduction as a "just and equitable" dollar figure rather than a fixed percentage, the story behind your fault can shift the outcome more than it would in a strict-formula state. If fault is contested and you are anywhere near the 50 percent line, that is the point to talk with a lawyer who tries these cases. You can start with the legal directory.
