From Wagon Trails to Interstate 70: 250 Years of American Roads and the Liability Law That Travels With Them
This summer the country marks two hundred and fifty years of American independence. The roads our family will travel for the holiday were not, two and a half centuries ago, anything close to what they are today. The first American roads were wagon trails. The first liability rules for collisions on those trails were borrowed from English common law, and they answered a question Americans were just learning to ask in their own way. When two travelers meet on a road and one is hurt, who pays?
We thought it was worth a moment, in a year of national reflection, to look at how American road law became Colorado road law. The arc from wagon trails to I-70 is also the arc of how this country built, tested, and refined a civil justice system that lets ordinary people hold negligent drivers accountable. The system is far from perfect, and we work inside its imperfections every day. But it is, by any honest historical measure, a substantial improvement on what came before.
This is a longer-form reflection than our typical practice posts. If you are reading because you have a claim, please call us at 720-928-9178. The conversation is free, there is no obligation, and there is no fee unless we win your case. If you are reading because you are interested in how American liability law became what it is, read on.
The Wagon Trail Era and the Common Law Inheritance
When the United States declared independence in 1776, the legal framework that governed road accidents was almost entirely English common law. The colonies had imported the English system of trespass and case actions, and accidents on roads were resolved under those frameworks for decades after independence.
The basic rule was simple in concept and rough in application. A traveler who caused harm to another through wrongful conduct could be sued for damages. “Wrongful conduct” was understood, by the standards of the time, as something close to deliberate misconduct or gross carelessness. Mere accident, in the modern sense, often did not produce liability at all. The law assumed that travel was risky and that people who suffered ordinary travel injuries should bear the cost themselves.
The system worked, more or less, when roads were trails and traffic was sparse. It started to strain as American population grew, as roads improved and were used by more people, and as the speed and scale of travel began to change.
The Coming of the Railroad and the Birth of Modern Tort Law
The American railroad arrived in earnest in the 1830s and changed everything about how the law thought about accidents. Railroads moved faster than wagons, carried more people, and produced injuries on a scale that had no precedent. The common law rules that had handled wagon collisions broke down under the volume and severity of railroad accidents, and American courts spent the second half of the nineteenth century rebuilding tort law around these new realities.
The doctrines we still use today, negligence as a distinct cause of action, the reasonable person standard, comparative fault, the eggshell plaintiff rule, contribution among defendants, all of these were either invented or substantially refined during the railroad era. By the time the automobile arrived at the start of the twentieth century, American tort law had developed a robust, flexible framework for thinking about how to allocate responsibility in fast-moving accident cases.
This framework, refined further through the automobile century, is the framework Colorado uses today.
The Automobile Era and the Rise of Insurance
The widespread adoption of the automobile in the early twentieth century brought a new wave of legal innovation. The first state mandatory auto insurance laws appeared in the 1920s. The first compulsory insurance laws followed. The financial responsibility laws that govern Colorado’s modern auto insurance system, codified in CRS 42-7-103 and elsewhere, are the descendants of these early twentieth-century reforms.
The insurance system did not just protect victims. It also fundamentally changed how tort law operates. When a defendant has insurance, the practical question of recovery shifts from “does this person have assets to pay” to “what does the policy cover and how much will the carrier pay.” This shift made tort recovery available to ordinary accident victims in a way it never had been before.
Colorado’s modern insurance framework, including UM/UIM coverage, MedPay, bad faith protections, and umbrella policies, is the product of a century of legislative and judicial refinement. We have written about the full picture of Colorado auto insurance in our pillar resource on the topic.
Colorado’s Particular Contribution
Colorado’s vehicle liability law reflects both the broad American tradition and specific Colorado choices.
The state’s modified comparative negligence rule under CRS 13-21-111 is one example. Colorado, like many states, moved away from the old contributory negligence rule that barred recovery if the plaintiff bore any fault for the accident. Colorado’s modified comparative system allows recovery as long as the plaintiff is less than fifty percent at fault, with recovery reduced by the percentage assigned. The fifty percent threshold reflects a Colorado legislative choice.
The state’s bad faith insurance laws under CRS 10-3-1115 and 10-3-1116 are another. These statutes provide some of the strongest protections in the country against insurance carriers that delay or deny clear claims. They were enacted because the legislature determined that the older common-law bad faith remedies were not sufficient to protect Colorado consumers.
The state’s longer three-year statute of limitations for motor vehicle tort claims, under CRS 13-80-101, is yet another. Most personal injury claims in Colorado have a two-year deadline. Motor vehicle claims have three. The choice reflects a recognition that auto accident claims often involve longer medical recovery and more complex insurance dynamics than other personal injury claims.
These are not abstract legal details. They are the specific tools Colorado claimants have available in 2026 because of choices the legislature and courts have made over the state’s history.
What 250 Years Tells Us About the Civil Jury
The most fundamental constitutional protection in any American personal injury case is the right to a civil jury trial under the Seventh Amendment to the United States Constitution. The right to have ordinary citizens, not judges and not government officials, decide whether an accident victim should be compensated and how much, is one of the most distinctive features of the American civil justice system.
Colorado adopted the right to a civil jury trial in its own constitution and its own court rules. Most Colorado car accident cases settle without ever reaching a jury, but the existence of the jury option shapes every settlement negotiation. Insurance carriers price their offers against the risk of what a jury might award. The strength and credibility of the claim, and the willingness of the lawyer to take a case to trial when necessary, directly affect what the carrier offers.
This is not a small thing. Two hundred and fifty years of American history have produced a civil justice system that puts the question of liability in the hands of citizens. The system is not perfect, and the work of representing accident victims requires navigating its imperfections daily. But the underlying principle, that a jury of peers decides who pays after an accident, is one of the most enduring contributions of the American legal tradition.
What This Means for Today’s Colorado Accident Victims
A driver hurt on US-36 today, in 2026, exercises rights that travel directly back through two hundred and fifty years of American legal development. The right to sue. The right to a jury. The right to compensation for actual damages. The right to recover in proportion to fault. The right to challenge an insurance carrier that fails to pay in good faith.
None of these rights existed in their modern form in 1776. All of them exist now because successive generations of legislators, judges, and lawyers built them. The work of representing Colorado accident victims, in the year of the country’s two hundred and fiftieth birthday, is a continuation of that work.
If you are an accident victim trying to understand your rights, the rights exist because of this history. They are also yours to exercise.
Frequently Asked Questions
How has Colorado’s car accident liability law changed over time?
Colorado’s modern liability framework includes the modified comparative negligence rule, statutory bad faith protections, the three-year statute of limitations for motor vehicle claims, and a robust insurance regulatory system.

Are car accident cases tried by juries in Colorado?
Most settle without going to trial. The right to a jury trial in civil cases is protected under both the United States Constitution and the Colorado Constitution, and the existence of the jury option shapes every settlement negotiation even when the case never actually reaches trial.
How long do I have to file a car accident claim in Colorado?
Three years from the date of the accident under CRS 13-80-101 for personal injury claims arising from a motor vehicle. Two years for wrongful death. 182 days notice for any claim against a governmental entity.
