What Are the Most Common Causes of Motorcycle Accidents in Pennsylvania?

Riding a motorcycle through Pennsylvania offers a sense of freedom that few other experiences match. The open road, the changing scenery from Pittsburgh's urban landscape to the rolling hills beyond, and the connection between rider and machine create something special. But that freedom comes with serious risks that every motorcyclist faces each time they start their engine.

Pennsylvania highways see devastating motorcycle crashes throughout the riding season. Many of these collisions result from other drivers failing to see motorcycles, misjudging their speed, or making careless decisions that violate riders' right-of-way. Motorcyclists lack the protective shell that surrounds people in cars and trucks. When crashes occur, riders absorb the full impact with their bodies.
The consequences can change everything in an instant. A moment of inattention by another driver can leave a motorcyclist with catastrophic injuries, mounting medical bills, and uncertain futures. Understanding what causes these crashes helps riders stay vigilant, but it also reveals how often negligent drivers are to blame. If you're unsure about your next steps after a motorcycle accident, reach out to Pribanic & Pribanic motorcycle accident lawyers in Pittsburgh, Pennsylvania, for guidance.

Key Takeaways: Causes of Pennsylvania Motorcycle Crashes

  • Left-turn accidents occur when drivers fail to yield right-of-way to oncoming motorcycles, causing devastating T-bone collisions at intersections.
  • Lane departure crashes happen when distracted or impaired drivers drift into motorcyclists' lanes or force them off the road entirely.
  • Following too closely gives drivers insufficient space to stop when motorcycles brake, leading to rear-end collisions that throw riders from their bikes.
  • Road hazards like potholes, gravel, and uneven pavement affect motorcycles far more severely than larger vehicles with four wheels.
  • Dooring incidents in urban areas injure motorcyclists when vehicle occupants open doors without checking for approaching traffic.
  • Inexperienced drivers often misjudge motorcycle speed and distance, making dangerous maneuvers that cut off riders or force emergency evasive action.
  • Call a motorcycle accident lawyer if another driver's negligence caused your crash to protect your rights and pursue full compensation for your injuries.

Left-Turn Collisions at Pennsylvania Intersections

The most common and severe motorcycle accidents occur when a driver turns left across the path of an oncoming bike. These crashes cause a large share of serious injuries and fatalities in Pennsylvania, often happening at intersections where a vehicle turns left while a motorcyclist travels straight or passes another car.

What Are the Most Common Causes of Motorcycle Accidents in Pennsylvania


Drivers making left turns must yield to oncoming traffic, including motorcycles, but many misjudge speed and distance or fail to see motorcycles entirely. This "looked but failed to see" issue happens when drivers glance at approaching traffic but do not register the motorcycle, pulling directly into its path. T-bone impacts from these collisions throw riders from their bikes, often onto the vehicle, the roadway, or into other traffic, causing severe injuries even when protective gear is worn.

Intersections along Liberty, Penn, and Fifth Avenue in Pittsburgh are common danger zones, particularly where left-turn signals are absent and drivers must judge gaps themselves. Pennsylvania law holds drivers accountable for failing to yield, and claiming they didn't see the motorcycle does not excuse negligence.

Our Pribanic & Pribanic motorcycle accident attorneys help injured riders collect intersection diagrams, traffic signal data, and witness statements to show how left-turn collisions happen and secure compensation for our clients' injuries.

Lane Departure Crashes and Sideswiping Incidents

Motorcycles require a full lane width just like any other vehicle. Pennsylvania law explicitly grants motorcyclists the right to use entire lanes and prohibits squeezing them toward lane edges. Despite these clear rules, many drivers treat motorcycles as if they don't need full lanes, leading to dangerous sideswiping collisions and forced lane departures.

Distracted driving causes many lane departure crashes. Drivers focused on cell phones, navigation systems, or passengers drift out of their lanes without realizing it. When a motorcycle occupies the adjacent lane, these unintended lane departures become collisions that throw riders from their bikes or force them to swerve into guardrails, curbs, or other traffic.

Intentional lane changes without proper checking cause similar results. Drivers glance at mirrors but don't check blind spots before moving over. Motorcycles can disappear in blind spots that swallow these smaller vehicles. When drivers change lanes on top of a motorcycle they didn't see, the rider has nowhere to go and limited time to react.

Impaired drivers create heightened risks for motorcyclists through their inability to maintain lane position. Alcohol and drugs affect motor control, making it difficult to keep vehicles centered in lanes. Their weaving paths can force motorcyclists off roadways entirely or create situations where evasive maneuvers lead to loss of control.

Road rage incidents sometimes involve drivers deliberately forcing motorcycles out of their lanes. These aggressive actions constitute assault with a deadly weapon, not mere negligence. Drivers who intentionally use their vehicles to threaten or harm motorcyclists face both criminal prosecution and civil liability.

The consequences of lane departure crashes vary depending on whether motorcyclists can maintain control. Some riders successfully avoid actual contact with the offending vehicle but crash anyway while taking evasive action. Pennsylvania law recognizes that drivers who force evasive maneuvers that result in crashes bear liability even without direct physical contact between vehicles.

Rear-End Collisions and Following Distance Failures

Rear-end crashes pose serious risks for motorcyclists. Unlike car-to-car collisions, even low-speed impacts can throw a rider forward, causing them to land on the road, strike the vehicle in front, or enter adjacent lanes where other traffic may hit them. These crashes often result in severe injuries that go far beyond what drivers in cars typically experience.

Tailgating is the most common cause. Motorcycles can slow faster than cars, and drivers following too closely often cannot react in time. Distracted driving at red lights and aggressive behaviors like crowding motorcycles from behind also lead to collisions.

Weather and poor visibility make these crashes more frequent. Fog, rain, and darkness increase stopping distances, making motorcycles harder to see. Our lawyers help Pittsburgh riders injured in rear-end crashes recover compensation and hold negligent drivers accountable.

Dangerous Road Conditions That Affect Motorcycles

Road hazards that barely affect cars can be devastating for motorcyclists. Potholes, loose gravel, and uneven pavement can cause a rider to lose balance in an instant. In Pennsylvania, where freeze-thaw cycles constantly damage roads, deep potholes and rough surfaces are common dangers.

Gravel, sand, and wet metal surfaces reduce traction and make steering unpredictable. Railroad tracks and construction zones add even more risk with bumps, slick spots, and shifting lanes. Each hazard demands quick reflexes from riders who have far less margin for error than drivers in enclosed vehicles. Government agencies may be responsible for unsafe road conditions, but these claims have strict deadlines.

Dooring Accidents in Urban Pittsburgh Areas

Dooring crashes happen when someone opens a car door into the path of a passing motorcyclist. In Pittsburgh's older neighborhoods, where narrow streets and curbside parking are common, these incidents pose a real danger to riders.

Dooring Accident


Drivers and passengers are required to check mirrors and look over their shoulders before opening a door. When they fail to do this, a motorcyclist has almost no time to react. Even at low speeds, hitting a door can throw a rider from their bike, causing serious injuries. Pennsylvania law holds the person who opened the door responsible.

Driver Inexperience and Misjudgment of Motorcycle Speed

Many drivers in Pennsylvania simply aren't used to sharing the road with motorcycles. They misjudge distances, speeds, and riders' intentions, leading to dangerous right-of-way violations. Because motorcycles are smaller, they often appear farther away and slower than they really are, causing drivers to pull out or turn directly into their paths.

Motorcycles also accelerate faster than most drivers expect, making it easy to underestimate how quickly they can reach an intersection. Lane positioning can add to the confusion when riders adjust within lanes for visibility or safety. Limited driver training on motorcycle awareness makes these risks worse.

How Weather Conditions Create Motorcycle Crash Risks

Weather affects every driver, but rain, fog, wind, and cold hit Pennsylvania motorcyclists much harder. Riders face reduced visibility, slippery roads, and less stability than people protected inside cars.

Rain cuts traction, especially when it first begins, and oil rises to the surface, making roads slick. Fog shortens sightlines, making motorcycles even harder to spot. Strong winds can push bikes sideways, and cold temperatures reduce tire grip and rider focus.

Many drivers fail to adjust for these conditions, following too closely or turning suddenly. We help riders injured in weather-related crashes across Pennsylvania pursue fair compensation from drivers who failed to share the road safely.

Impaired and Distracted Driving Dangers for Riders

Impaired and distracted drivers create serious dangers for Pennsylvania motorcyclists. Alcohol slows reaction times and clouds judgment, causing drivers to misjudge speed, distance, and turning gaps. Drug impairment, from illegal substances or prescription medication, leads to drowsiness, confusion, or distorted vision that often results in lane drifting or missed signals.

Distracted driving is just as dangerous. Many crashes happen when drivers look down to text or scroll through their phones instead of watching the road. Even small distractions from passengers, food, or navigation systems can stop them from seeing a motorcyclist in time.

Proving Fault in Pennsylvania Motorcycle Accident Cases

Proving who caused a motorcycle crash takes clear evidence and careful investigation. In Pennsylvania, insurers often try to blame riders, so documenting every detail matters. Police reports are a strong starting point, noting road conditions, witness accounts, and possible violations that can indicate negligence.

Photos from the scene capture fading evidence like skid marks, damage, and traffic signs that reveal how the crash occurred. Witness statements add unbiased perspectives, while medical records link your injuries directly to the collision. If a driver violated traffic laws, that can serve as proof of negligence under Pennsylvania law.

At Pribanic & Pribanic, we help riders across western Pennsylvania gather vital evidence, work with reconstruction professionals, and fight to hold negligent drivers fully accountable.

Pennsylvania Motorcycle Accident FAQs

What should I do immediately after a motorcycle accident?

Seek medical attention right away even if you don't feel badly hurt, report the crash to police, photograph the scene and your injuries if possible, and contact a motorcycle accident attorney before providing statementso insurance companies.

Can I recover compensation if I wasn't wearing a helmet?

Pennsylvania law requires helmets only for riders under 21 or those without sufficient experience or insurance. If you weren't legally required to wear one, the lack of a helmet doesn't automatically bar recovery. However, it might affect compensation for head injuries depending on specific circumstances.

How long do I have to file a motorcycle accident lawsuit in Pennsylvania?

Pennsylvania's statute of limitations gives you two years from the accident date to file most personal injury lawsuits. Acting promptly helps preserve evidence and protects your legal rights.

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

Your own uninsured motorist coverage can provide compensation when at-fault drivers lack insurance. Pennsylvania law requires carriers to offer this coverage, though drivers can reject it in writing. An attorney can help identify all available coverage sources.

Do most motorcycle accident cases go to trial?

Most cases settle through negotiations without trials, but having an attorney prepared to take your case to court strengthens your negotiating position and often leads to better settlement offers from insurance companies.
