Winning Trials since 1979

Highways are designed for speed, convenience, and connectivity, but they can also be the scene of some of the most devastating motor vehicle accidents. With high speeds, multiple lanes, and dense traffic, highway crashes often result in serious injuries, property damage, or even fatalities. 

Understanding the most common causes of highway accidents and how to avoid them is key to protecting yourself and others on the road. Whether you’re a daily commuter or an occasional traveler, safe driving habits can make a life-saving difference.

At Local Accident Reports, we’ve worked with countless accident victims across the country and seen firsthand how preventable many highway crashes truly are. Below, we break down the leading causes of these collisions and offer practical tips to reduce your risk.

Speeding

Speeding remains one of the top causes of highway crashes nationwide. Drivers who exceed the speed limit have less time to react to traffic changes, road hazards, or sudden stops. High-speed collisions also result in more severe injuries and damage due to the force of impact.

Why it happens:

  • Drivers running late
  • Misjudging the speed of traffic flow
  • Lack of awareness of speed limit changes

How to avoid it:

  • Always obey posted speed limits and adjust your speed for weather or traffic conditions.
  • Use cruise control to maintain a safe and consistent speed.
  • Leave early to avoid the temptation to speed when you’re behind schedule.

Distracted Driving

Distracted driving has become a leading cause of highway crashes, particularly with the rise of smartphones and in-car technology. Even a few seconds of taking your eyes off the road can lead to a serious collision at high speeds.

Common distractions include:

  • Texting or talking on the phone
  • Adjusting the radio or GPS
  • Eating or drinking
  • Reaching for items in the car

How to avoid it:

  • Put your phone on “Do Not Disturb” mode or store it out of reach.
  • Set your GPS and music preferences before you begin driving.
  • Pull over at a safe rest area if you need to eat or handle something urgent.

Tailgating

Following another vehicle too closely, especially at highway speeds, drastically reduces your ability to stop in time if the driver in front of you brakes suddenly. Rear-end collisions on highways are common and often avoidable with proper spacing.

Why tailgating happens:

  • Impatience in traffic
  • Aggressive driving
  • Misjudging stopping distances

How to avoid it:

  • Maintain a minimum of a three-second following distance; more if it’s raining or the roads are slick.
  • Avoid aggressive lane changes or weaving through traffic.
  • Stay calm in traffic jams and remember that reaching your destination safely is more important than getting there fast.

Fatigued Driving

Driving while drowsy is a hidden danger on long highway trips. Fatigue slows reaction time, impairs judgment, and can lead to microsleeps, brief moments when the brain actually falls asleep while your eyes remain open.

Risk factors include:

  • Driving late at night or during early morning hours
  • Long-haul truck driving without sufficient rest
  • Sleep disorders or inconsistent sleep habits

How to avoid it:

  • Take regular breaks during long trips (at least every two hours).
  • Get a full night’s sleep before embarking on road travel.
  • Share driving responsibilities with a passenger if possible.
  • Watch for signs of drowsiness, such as yawning, heavy eyelids, or drifting from your lane.

Impaired Driving

Driving under the influence of alcohol or drugs is illegal and extremely dangerous. Impairment affects coordination, decision-making, and reaction time, factors that are even more critical when driving at highway speeds.

It’s not just alcohol:

  • Marijuana, prescription drugs, and over-the-counter medications can also impair your ability to drive safely.

How to avoid it:

  • Never get behind the wheel if you’re under the influence.
  • Use a designated driver, rideshare service, or taxi if you’ve been drinking or taking impairing substances.
  • Read labels and warnings on medications, and consult with your doctor or pharmacist about potential side effects.

Poor Weather Conditions

Rain, fog, snow, and ice all pose significant risks on the highway. Reduced visibility, slippery roads, and longer stopping distances are common in poor weather, making crashes more likely.

Common weather-related crash scenarios:

  • Hydroplaning on wet roads
  • Reduced traction during snow or ice storms
  • Rear-end collisions in fog due to low visibility

How to avoid it:

  • Reduce your speed during inclement weather.
  • Use headlights in low-visibility conditions.
  • Avoid sudden braking or acceleration.
  • Keep your vehicle maintained with proper tire tread and working wipers.

Improper Lane Changes and Merging

One of the most dangerous behaviors on highways is executing sudden or unsafe lane changes. Failure to signal, not checking blind spots, or cutting off other vehicles can result in serious side-swipe or rollover accidents.

Highway merging accidents often occur when:

  • Drivers speed up or slow down unpredictably on entrance ramps
  • Others fail to yield or adjust to merging traffic

How to avoid it:

  • Always use turn signals well in advance.
  • Check mirrors and blind spots before changing lanes.
  • Merge smoothly and allow others space when they are entering the highway.

Vehicle Malfunctions

Mechanical issues like tire blowouts, brake failure, or engine trouble can quickly become catastrophic on highways. While some mechanical failures are unpredictable, many are preventable with regular maintenance.

To reduce the risk of breakdowns or failures:

  • Schedule routine inspections for brakes, tires, fluids, and lights.
  • Address warning lights and dashboard indicators promptly.
  • Carry an emergency kit and know how to pull over on a highway shoulder safely.

What to Do If You’re Involved in a Highway Crash

Even with the best precautions, accidents can still happen. If you’re involved in a highway collision, the most important steps are to prioritize safety and seek medical attention.

After a highway accident, be sure to:

  • If possible, move to a safe location and turn on hazard lights.
  • Call 911 and report the accident to the proper authorities.
  • Seek medical evaluation, even if you don’t feel injured right away.
  • Take photos of the scene, vehicles, and any visible injuries.
  • Get contact information from witnesses and the other driver.
  • Contact an experienced car accident attorney as soon as possible.
