The Maryland boulevard rule puts the burden on any driver entering or crossing a main road to yield to traffic already on it, and if a collision happens, that entering driver is treated as negligent as a matter of law. Combined with Maryland’s status as one of only five U.S. jurisdictions that still follow pure contributory negligence, it creates one of the strictest right-of-way frameworks in the country: being even slightly at fault can wipe out your right to recover anything.1Maryland Department of Legislative Services.

The Two Statutes Behind the Rule
Two sections of the Maryland Transportation Code do the work. Section 21-403 covers intersections controlled by stop or yield signs. If you approach a through highway, you must stop at the entrance and yield to any vehicle already on that highway. At a yield sign, you must approach with caution, yield to approaching traffic, and stop if necessary.2Maryland General Assembly. Maryland Transportation Code 21-403 – Vehicle Entering Intersection
Section 21-404 covers the other common scenario: entering a highway from somewhere that isn’t another highway. Pulling out of a driveway, a parking lot, an alley, or a private road, you must stop before entering the highway and yield to any approaching vehicle.3Maryland General Assembly. Maryland Code Transportation 21-404 – Entering Highway From Other Than Highway The duty is absolute. Stop first, then yield. Not one or the other.
Together, these sections cover virtually every place where a driver transitions from a subordinate road or private space onto a main road. The curb cut where a shopping center lot meets the street, the end of your driveway, the exit from a parking garage, the stop sign at a side street meeting a bigger road — these are all places the boulevard rule applies.
Favored and Unfavored Drivers
Maryland courts split drivers in these situations into two categories. The favored driver is the one already traveling on the through highway or the road with the right-of-way. The unfavored driver is the one approaching from a side street, driveway, or other subordinate position. These are not just descriptive labels. They carry very different legal consequences when something goes wrong.
If you’re the unfavored driver, your job is straightforward but demanding: come to a complete stop, assess whether you can enter or cross safely, and only proceed when you’re certain you won’t interfere with any favored traffic. Misjudge, and the law treats you as the one at fault.4Appellate Court of Maryland. Madison Mohr-Keys v Carole Moulsdale
If you’re the favored driver, you’re legally entitled to assume that other drivers will obey stop and yield signs. You don’t have to slow at every intersection on the chance that someone might pull out in front of you. That assumption is what keeps traffic moving on Maryland’s main roads.
Automatic Fault for the Unfavored Driver
This is where the rule earns its reputation. If you’re the unfavored driver and a collision happens while you’re entering or crossing the favored road, Maryland courts treat you as negligent as a matter of law. The court does not need to hear testimony about whether you looked both ways or thought you had enough room. Entering the road and getting hit is enough to establish fault.4Appellate Court of Maryland. Madison Mohr-Keys v Carole Moulsdale
Most car accident cases require showing that someone acted unreasonably. Under the boulevard rule, that step is essentially skipped. The violation of the duty to yield is the negligence. Defending these cases is hard because the unfavored driver starts at a severe disadvantage before any other facts come in.
Why Contributory Negligence Cuts Both Ways
Maryland is one of only five U.S. jurisdictions — along with Alabama, North Carolina, Virginia, and the District of Columbia — that still follows pure contributory negligence. Under this doctrine, if you are even partly at fault for an accident, you cannot recover any damages at all.1Maryland Department of Legislative Services. Contributory Negligence, Comparative Fault, and Joint and Several Liability Most states use comparative negligence, which reduces your recovery by your percentage of fault. Maryland’s approach is all-or-nothing.
For boulevard rule cases, that works both directions. If you’re the unfavored driver and you caused the collision, you’re negligent as a matter of law, and you recover nothing from the favored driver. But if you’re the favored driver and the unfavored driver can show you were also negligent, say by speeding significantly or being distracted by your phone, your contributory negligence could bar you from recovering anything, even though you had the right-of-way.
Maryland courts have held that a favored driver’s excessive speed by itself isn’t automatically contributory negligence. It only matters if the speed was a proximate cause of the accident. The test is whether a reasonably prudent person in the favored driver’s position would have acted differently. If reasonable minds could disagree, the question goes to a jury.
When the Favored Driver Loses Protection
The rule doesn’t protect a favored driver who was driving unlawfully at the time of the crash. Running a red light, being intoxicated, or otherwise breaking traffic laws can strip you of favored status. The key question is whether the unlawful behavior was a proximate cause of the collision. If it was, the normal boulevard rule analysis shifts, and a jury may consider whether both drivers share responsibility.
This matters in practice. An unfavored driver who would otherwise face automatic liability may escape that result by showing the favored driver was doing something illegal that directly contributed to the crash. Even slight evidence of the favored driver’s negligence can be enough to send the issue to a jury rather than having it decided by a judge.
The Last Clear Chance Doctrine
Maryland recognizes one important escape valve from contributory negligence: the last clear chance doctrine. A plaintiff who was contributorily negligent can still recover if the defendant had a fresh opportunity to avoid the crash after the danger became apparent and failed to take it.
The doctrine requires something sequential. Not just that both drivers were negligent at the same time, but that the defendant had a distinct later moment when they could have prevented the collision. If both drivers’ negligence was happening simultaneously and continuously, last clear chance doesn’t apply.4Appellate Court of Maryland. Madison Mohr-Keys v Carole Moulsdale
In a typical boulevard rule scenario, this might look like an unfavored driver who pulled partway into the road and stopped, giving the favored driver several seconds and a clear line of sight to brake or steer around, but the favored driver was looking at a phone and never reacted. The unfavored driver was still wrong to enter the road, but the favored driver had a fresh chance to avoid the impact and did not take it. These cases are fact-intensive and hard to win, but they do succeed when the timeline clearly shows the favored driver could have acted.
Fines and Points
A traffic citation for violating the boulevard rule carries a base fine of $110. If the violation contributed to an accident, the fine increases to $150. When the violation contributed to an accident causing death or serious bodily injury, the fine jumps to $750.5Maryland Courts. District Court of Maryland Fine Schedule These levels apply to both Section 21-403 violations at intersections and Section 21-404 violations when entering a highway from a driveway or private road.
Points follow the same escalation. A boulevard rule violation without an accident carries one point on your driving record. Any moving violation that contributes to an accident, including a failure to yield, carries three points.6Maryland General Assembly. Maryland Code Transportation 16-402 – Point System
Insurance and Civil Exposure
The traffic fine is usually the smallest financial hit. Because the unfavored driver is treated as negligent as a matter of law, insurers generally assign full fault without much debate. Your carrier will likely pay the favored driver’s claim and raise your premiums. A single at-fault accident can increase auto insurance rates for three to five years, and a moving violation on top of it compounds the effect.
The bigger exposure is civil liability. If the favored driver or any passengers were injured, you face a personal injury claim where your negligence is already established. The only questions left are the extent of the injuries and the dollar amount. That’s why boulevard rule claims tend to settle or succeed at higher rates than ordinary accident cases. If damages exceed your policy limits, the difference comes out of your own pocket.
What to Do as a Driver
If you’re approaching a through highway from a side street or driveway, come to a full and complete stop before the road, not a rolling pause. Look in both directions and account for the speed of approaching traffic, not just whether you see a car. The most common boulevard rule accidents happen when a driver sees a gap that looks wide enough but underestimates how fast the favored vehicle is traveling. If there’s any doubt, wait for the next gap.
If you’re the favored driver involved in a collision with someone who pulled out in front of you, document everything. Photograph the intersection, the stop or yield signs, and any skid marks. Get the police report, which will typically note the right-of-way violation. Even though the rule works in your favor, the unfavored driver’s attorney will look for any evidence that you were speeding, distracted, or otherwise negligent. In Maryland, your own contributory negligence can erase your right to compensation entirely.
For either driver, talking to an attorney early matters more in Maryland than in most states. Negligence as a matter of law, contributory negligence as a complete bar, and the last clear chance doctrine together create a situation where small factual details about timing and positioning can swing a case from full recovery to zero. Getting those details locked in from the start is the most useful thing you can do after a boulevard rule accident.
