    Understanding the Most Common Causes of Highway Breakdowns

Engine Overheating – A Leading Cause of Roadside Breakdowns

Engine overheating is one of the most frequent causes of highway breakdowns, particularly during the summer months. Overheating occurs when the cooling system fails, coolant levels are too low, or there’s a radiator leak. High temperatures and long drives put added strain on the engine, making it more susceptible to breakdowns.

How to Prevent Your Engine from Overheating

  • Regularly check coolant levels and top off if necessary.

  • Inspect the radiator, water pump, and hoses for leaks or wear.

  • Never drive with an overheating engine—pull over and let it cool.

  • Keep an eye on the temperature gauge and act quickly if it rises.

Flat Tires and Blowouts – What Leads to Tire Failures?

A flat tire or blowout is another common reason for roadside breakdowns. Poor tire maintenance, incorrect pressure, and driving over debris can lead to sudden tire failure, leaving you stranded on the side of the road.

Checking Tire Pressure and Tread Depth Regularly

  • Check tire pressure before long trips.

  • Inspect tread depth using the penny test.

  • Rotate tires every 5,000 to 7,500 miles to ensure even wear.

  • Carry a spare tire, jack, and tire iron at all times.

Battery Failure – Avoid Getting Stranded on the Highway

A dead battery can leave you stranded without warning, especially in cold weather. Battery failure is often caused by corroded terminals, extreme temperatures, and electrical drain from accessories left on.

Signs Your Car Battery Needs Replacement

  • The engine cranks slowly or struggles to start.

  • Headlights and interior lights appear dim.

  • There’s corrosion around the battery terminals.

  • Your battery is more than three years old.


    How to Prevent Highway Breakdowns Before They Happen

Importance of Regular Vehicle Maintenance

Routine car maintenance is crucial in preventing breakdowns. Schedule regular oil changes, fluid checks, and brake inspections to ensure everything is functioning properly.

Conducting a Pre-Trip Vehicle Inspection

Before hitting the road, always check:

  • Fluids (oil, coolant, brake fluid, transmission fluid)

  • Tires (pressure and tread depth)

  • Battery health and electrical systems

  • Brakes and warning lights

Essential Roadside Safety Tips When Your Car Breaks Down
