Watch for:

• Slow engine cranking

• Clicking

• Intermittent starting

• Dimming electrical systems during startup

• Battery warning concerns

Remember that starting problems can also involve the:

• Starter

• Alternator

• Wiring

• Connections

A battery test can help determine its condition.

Step 9: Check the Charging System if You Have Concerns

The alternator helps power electrical systems and recharge the battery while the engine is running.

Possible warning signs of charging problems include:

• Battery warning light

• Dimming lights

• Electrical problems

• Repeated dead battery

• Unusual noises

If you've noticed any of these symptoms, get the charging system tested before traveling.

A vehicle that loses charging ability hundreds of miles from home can eventually shut down.

Step 10: Inspect the Brakes

You don't need to remove the wheels to notice many brake symptoms.

During normal driving before your trip, pay attention to:

• Squealing

• Grinding

• Pulsation

• Steering-wheel vibration while braking

• Vehicle pulling

• Longer stopping distance

• Brake warning lights

• Unusual pedal feel

If the brakes already feel questionable around town, highway travel isn't the time to test how much longer they'll last.

Have them inspected.

Step 11: Think About Where You're Driving

A flat interstate trip and a mountain road trip place different demands on a vehicle.

If you'll be driving through mountainous terrain, brakes become especially important.

Long downhill grades can generate substantial brake heat.

Know how to use appropriate transmission gearing and follow your vehicle manufacturer's guidance.

Don't ride the brakes continuously down long grades.

If you're towing, brake and cooling-system demands increase further.

Step 12: Check Every Exterior Light

Have someone help you or safely use reflections where appropriate.

Check:

• Low-beam headlights

• High beams

• Brake lights

• Turn signals

• Hazard lights

• Tail lights

• Reverse lights

• License-plate lights

• Fog lights if equipped

Lights aren't just for nighttime.

They allow other drivers to understand what you're doing.

Replace failed bulbs or repair lighting problems before leaving.

Step 13: Check Your Wipers

Run the windshield wipers with washer fluid.

Look for:

• Streaking

• Chattering

• Skipping

• Torn rubber

• Areas left uncleared

If the blades aren't clearing the windshield properly, replace them.

Wipers are inexpensive compared with trying to see through heavy rain at highway speed.

If your vehicle has a rear wiper, check that too.

Step 14: Inspect the Windshield

Look for:

• Cracks

• Significant chips

• Damage in the driver's viewing area

Small windshield damage can sometimes spread.

Temperature changes, vibration, and road impacts during a long trip may make existing damage worse.

Have questionable damage evaluated before leaving.

Step 15: Test the Air Conditioning and Heat

Climate control isn't only about comfort.

Air conditioning and defrost functions can help manage windshield fogging and visibility.

Test:

• AC

• Heat

• Blower fan

• Defrost

• Vent modes

If you're heading into extremely hot or cold conditions, climate-system problems become much more important.

Step 16: Check the Belts and Hoses Where Visible

On vehicles with accessible belts and hoses, visually look for:

• Cracks

• Fraying

• Obvious deterioration

• Fluid contamination

• Bulges in hoses

• Leaks around connections

Don't put your hands near belts, fans, pulleys, or other moving components while the engine is running.

If something looks questionable, have a professional inspect it.

Step 17: Check Your Dashboard for Warning Lights

Don't start a long trip with an unexplained warning light.

Pay attention to:

• Check Engine

• Battery

• Oil pressure

• Temperature

• ABS

• Brake

• Airbag

• TPMS

• Stability/traction control

Some warnings may represent minor issues.

Others may indicate problems that can leave you stranded or affect safety.

Find out what the warning means before the trip.

Step 18: Pay Attention to Existing Noises

Think about the last few weeks of driving.

Has the vehicle developed:

• Humming?

• Grinding?

• Clicking?

• Clunking?

• Squealing?

• Vibration?

Don't tell yourself:

"I'll deal with it after vacation."

A wheel bearing that's already getting louder or a CV axle that's already clicking isn't improved by adding another 1,500 highway miles.

Have new or worsening symptoms evaluated.

Step 19: Take a Short Pre-Trip Test Drive

A few days before leaving, drive the vehicle long enough to reach normal operating temperature.

Include highway speed if safe and practical.

Pay attention to:

• Steering

• Brakes

• Transmission

• Engine temperature

• Vibration

• Warning lights

• AC

• Unusual noises

Then park and inspect again.

Look underneath for fresh leaks.

Smell for:

• Coolant

• Burning oil

• Fuel

• Hot brakes

• Electrical burning

This is essentially a rehearsal for the trip.

Step 20: Check Your Maintenance Schedule

Look at your owner's manual or maintenance records.

Ask:

What's due now?

What's going to become due during the trip?

Potential services may include:

• Engine oil

• Filters

• Tire rotation

• Brake inspection

• Coolant service

• Transmission service

• Spark plugs

• Fuel filter on applicable diesel vehicles

You don't necessarily need to perform every future service early.

But you should know where the vehicle stands.

Step 21: Consider the Vehicle's Age and Mileage

A 3-year-old vehicle with 30,000 miles and a 15-year-old vehicle with 180,000 miles may need different levels of preparation.

For an older or higher-mileage vehicle, consider having a professional specifically inspect:

• Cooling system

• Belts

• Hoses

• Suspension

• Wheel bearings

• Battery/charging system

• Fluid leaks

• Brakes

Older vehicles can absolutely make long trips reliably.

Preparation matters.

Step 22: Pack an Emergency Kit

Even a perfectly maintained vehicle can experience:

• Tire puncture

• Road debris damage

• Collision

• Weather event

• Unexpected mechanical failure

Carry basic emergency supplies appropriate for your trip.

Consider:

• Flashlight

• Phone charging cable/power bank

• First-aid kit

• Drinking water

• Basic tools

• Reflective warning devices

• Work gloves

• Jumper cables or appropriate jump pack

• Tire-pressure gauge

• Emergency contact information

• Weather-appropriate clothing or blanket

Adjust the kit based on where you're traveling.

Remote mountain roads require different preparation from driving between major cities.

Step 23: Carry Water for People — Not as a Substitute for Coolant

Drinking water belongs in your emergency kit.

But don't plan on roadside water as your normal cooling-system maintenance strategy.

Modern vehicles often require specific coolant formulations.

If your vehicle has an existing coolant leak, repair it before traveling rather than packing fluid and hoping for the best.

Step 24: Check Your Roadside-Assistance Coverage

Know before you leave whether you have roadside assistance through:

• Auto insurance

• Vehicle manufacturer

• Extended warranty

• Membership program

• Credit-card benefit

• Other service

Understand what it covers.

Also know how to request service.

Don't wait until you're stranded with poor cellular service to start looking for the phone number.

Step 25: Download Important Information

Cellular service isn't guaranteed everywhere.

Consider having offline access to:

• Route/maps

• Hotel information

• Emergency contacts

• Insurance information

• Roadside-assistance information

Technology is extremely useful.

Prepare for the possibility that it doesn't have a signal.

Step 26: Don't Overload the Vehicle

Road trips mean luggage.

Sometimes a lot of luggage.

Every vehicle has weight limits.

Payload includes more than what you put in the trunk or bed.

It can include:

• Passengers

• Luggage

• Cargo

• Accessories

• Trailer tongue weight where applicable

If you're carrying unusually heavy loads or towing, verify the vehicle's ratings.

Exceeding them can affect:

• Braking

• Handling

• Tires

• Suspension

• Cooling

Step 27: If You're Towing, Inspect More

Towing adds another layer of preparation.

Check:

• Hitch

• Hitch hardware

• Safety chains

• Trailer wiring

• Trailer lights

• Trailer tires

• Trailer brakes where applicable

• Trailer wheel bearings as appropriate

• Correct tongue weight and loading

• Tow vehicle ratings

A road-trip inspection for a towing vehicle should include both the tow vehicle and the trailer.

Step 28: Check Tire Pressure Again the Morning You Leave

Even if you checked several days earlier, do one final pressure check before departure.

A slow puncture may reveal itself.

Check:

All four tires.

And ideally:

The spare.

It takes only a few minutes.

Step 29: Pay Attention During the Trip

The inspection doesn't end when you leave home.

At fuel or rest stops, walk around the vehicle.

Look for:

• Low tire

• Fluid leak

• Unusual smell

• Smoke

• Damage

• Anything hanging underneath

Pay attention to changes in:

• Steering

• Braking

• Vibration

• Temperature

• Engine sound

A new symptom deserves attention.

Don't keep driving simply because you're trying to stay on schedule.

When Should You Stop Driving?

Pull over safely and investigate or seek assistance if you experience serious symptoms such as:

• Engine overheating

• Oil-pressure warning

• Severe vibration

• Major tire damage

• Smoke

• Strong fuel smell

• Serious brake problems

• Significant fluid loss

• Sudden steering problems

The goal of the road trip is to arrive.

The schedule comes second.

Then take one final look at the vehicle before you leave.

The Bottom Line

A road trip shouldn't begin with:

"I hope the car makes it."

You don't need to replace half the vehicle before every vacation.

You simply need to know its condition.

Check the tires.

Check the fluids.

Test the battery.

Pay attention to the brakes.

Check the lights.

Replace bad wipers.

Inspect the spare.

Pack emergency supplies.

And address anything the vehicle has already been trying to tell you.

Because the best place to discover a problem isn't at a gas station 400 miles from home.

It's in your driveway while you still have time to fix it.

Getting Ready for a Long Road Trip?

If you're unsure whether your vehicle is ready, FixFlowIQ can help you compare inspection and maintenance options from vetted automotive professionals.

When submitting your request, tell the provider:

Year • Make • Model • Mileage • Approximate Trip Distance

And mention any concerns you've noticed.

For example:

"Battery has been cranking slowly."

"One tire keeps losing pressure."

"I hear a humming noise on the highway."

"Coolant level has been dropping."

Those details help a technician focus the inspection on what matters.

Inspect it before the trip. Fix problems before they become breakdowns. Then enjoy the drive.
