What Causes 90% of Car Accidents in Maryland?

More than 90% of car accidents in Southern Maryland start with the driver. That’s based on research from the National Highway Traffic Safety Administration, which found that the “critical reason” for the crash was attributed to the driver in 94% of cases studied. NHTSA is careful to note this isn’t the same as blame or fault — it’s the last failure in the chain of events leading up to the crash. But the data points in one direction: the vast majority of crashes start with something the driver did or failed to do.

In Maryland, those driver-related causes fall into two big categories: aggressive driving and operator impairment.

The rule that follows is simple. If a driver causes a wreck, that driver pays for it. Think of the old “you break it, you buy it” sign at a gift shop. If Laura knocks a coffee mug off the shelf, she has to replace it. If Laura runs a red light and hits another car, she has to make the victim whole.

In a perfect world, at-fault drivers would just hand over a check. That’s not how it works. Insurance companies push back. They argue. They lowball. That’s where a Charles County personal injury lawyer comes in. Claimants with attorneys typically recover larger settlements than those who handle insurance companies alone.

Aggressive Driving on Maryland Roads

Aggressive driving is usually careless driving. Drivers stop watching the speedometer. They drift. They get in a hurry. Speed is the most dangerous form of all.

A car does not stop on a dime. Stopping is a process. It starts the second a driver spots a hazard. The driver must move a foot to the brake and bring the car to a safe halt. That whole chain takes about a second.

Here is the problem. At 30 mph, a car covers about six car lengths in that second. At 60 mph, it covers eighteen. So at higher speeds, a crash is almost certain when something goes wrong ahead.

Speed also makes crashes worse — and not in a linear way. The energy released in a crash scales with the square of speed. Doubling your speed quadruples the impact force. A small fender-bender at 25 mph can become a serious or fatal wreck at 50 mph. Loose items inside the cabin, like phones and water bottles, also turn into projectiles.

A Maryland auto accident lawyer can still recover money even if the at-fault driver wasn’t technically over the posted limit. Driving 45 mph in heavy fog on Route 301 is unsafe, even if the speed limit says 55. Compensation usually covers medical bills, lost wages, and pain and suffering. For a deeper look at how Maryland law treats high-risk driving behavior, see our piece on aggressive driving accidents in Maryland.

Other common forms of aggressive driving include:

• Running red lights and stop signs
• Following too closely (tailgating)
• Unsafe lane changes
• Distracted driving, including texting while driving
• Failure to yield

Operator Impairment

If aggressive driving is careless, operator impairment is selfish. These drivers know they shouldn’t be behind the wheel. They drive anyway. The four most common forms are below.

Alcohol and Drugs

Most people think of beer and liquor first. But this category also covers prescription drugs and over-the-counter medications. Anything that slows reaction time counts. Even some allergy and cold medicines carry warnings against operating a vehicle.

Drowsiness

Being awake for 18 straight hours produces driving impairment roughly equivalent to a 0.05 blood alcohol level, according to research cited by the CDC and NHTSA. A long shift or a late drive home from D.C. on Route 5 can do it. Drowsy drivers drift across lanes. They misjudge gaps. They react slower to hazards.

Medical Conditions

A bad cold can blur vision and slow reactions. More serious conditions, like heart disease or epilepsy, can cause a driver to black out behind the wheel. Drivers who know they have these conditions still owe a duty of care to other people on the road.

Texting and Phone Use

Five seconds of looking at a phone at 55 mph means traveling the length of a football field with your eyes off the road. Maryland’s hands-free law makes most phone handling illegal while driving. It is also one of the easiest forms of impairment to prove in court.

The people put at risk include other drivers, passengers, and pedestrians. Compensation is usually available for all of them, including in wrongful death cases when a crash turns fatal.

What Maryland Drivers Should Do After a Crash

Steps to take at the scene matter more than most people realize:

• Call 911. Always get a police report, even for minor wrecks.
• Photograph everything. Damage to both cars, the road, skid marks, and any visible injuries.
• Get contact info. Names, phone numbers, insurance details, and license plates of all drivers and witnesses.
• See a doctor. Even if you feel fine. Injuries like whiplash and concussions often show up days later.
• Don’t admit fault. Stick to facts when talking to police or other drivers.
• Call a lawyer before the insurance company. Adjusters record statements and use them later.

Frequently Asked Questions

What is the leading cause of car accidents in Maryland?

Driver error is the critical factor in about 94% of crashes, according to NHTSA’s National Motor Vehicle Crash Causation Survey. In Maryland, that breaks down into two big buckets: aggressive driving (speeding, running lights, tailgating, unsafe lane changes) and operator impairment (alcohol, drugs, drowsiness, distraction). Distracted driving alone accounts for roughly 45% of crashes in Maryland, per MDOT’s Highway Safety Office.

Do I need a lawyer for a Maryland car accident?

Not always, but it usually helps. Maryland uses a strict contributory negligence rule. If you are found even 1% at fault, you can be barred from recovering anything. A lawyer protects you from that outcome. For more detail on how this rule works, see Maryland’s contributory negligence rule.

What is the #1 cause of car accidents in Maryland?

Distracted driving. A multi-year MDOT study found about 56,000 distracted-driving incidents per year in Maryland, accounting for roughly 45% of all crashes statewide. Texting is the most dangerous form because it combines visual, manual, and cognitive distraction at the same time. Nationally, NHTSA reported 3,208 deaths and 315,167 injuries from distracted-driving crashes in 2024.

How long do I have to file a car accident claim in Maryland?

Maryland’s general statute of limitations for personal injury is three years from the date of the accident under Md. Cts. & Jud. Proc. § 5-101. Wrongful death claims also have a three-year window. Claims against a state or local government agency require a written notice of claim within one year of the injury under the Maryland Tort Claims Act or Local Government Tort Claims Act. Miss the notice deadline and you can lose the right to sue even within the three-year window.

What if the driver who hit me doesn’t have insurance?

You may still recover through your own uninsured motorist coverage (UM), which every Maryland auto policy includes by default unless waived in writing. If the at-fault driver has insurance but not enough to cover your injuries, underinsured motorist (UIM) coverage on your own policy can bridge the gap. Maryland also allows enhanced UIM (EUIM) coverage that stacks on top of the at-fault driver’s policy rather than offsetting it.
