A hard pothole impact can damage tires, wheels, steering, suspension, and more. Learn what warning signs to watch for, when to stop, what you can safely inspect, and when the vehicle should be towed instead of driven.
You're driving when:
BANG!
One wheel drops into a pothole.
The impact is hard enough to make you wince.
You keep driving.
But something doesn't feel right.
Maybe:
The steering wheel is no longer straight.
The vehicle pulls to one side.
You feel a new vibration.
You hear:
Thumping.
Scraping.
Clunking.
or:
Grinding.
Maybe a tire-pressure warning appears.
Or perhaps you don't notice anything until you begin accelerating again.
A hard pothole impact can potentially affect more than:
Your alignment.
Depending on the severity and location of the impact, damage can involve:
Tire
Wheel
Wheel bearing
Steering components
Suspension components
Underbody components
Exhaust
Fluid-carrying components
Other parts of the vehicle
Your priorities should be:
MAINTAIN CONTROL.
PAY ATTENTION TO WHAT CHANGED.
REDUCE SPEED IF SOMETHING FEELS WRONG.
FIND SOMEWHERE SAFE TO STOP.
INSPECT ONLY WHEN CONDITIONS ARE SAFE.
DON'T IMMEDIATELY RETURN TO HIGHWAY SPEED IF THE VEHICLE ISN'T BEHAVING NORMALLY.
The pothole itself is only part of the story.
What matters next is:
How did the vehicle change?
Ask yourself:
Did the steering begin pulling?
Did the steering wheel move off-center?
Did vibration begin?
Did you hear a new noise?
Did the tire-pressure warning come on?
Does the vehicle feel unstable?
Is something scraping?
Did a warning light appear?
Can you smell fluid or something burning?
These observations can help determine how urgently you need to stop.
This is one of the biggest mistakes after hitting a pothole.
The vehicle begins pulling and the driver thinks:
“I knocked the alignment out.”
Maybe.
But pulling can potentially result from:
Tire damage
Pressure loss
Wheel damage
Steering-component damage
Suspension damage
Alignment change
Other mechanical problems
An alignment machine should not be used to hide damaged parts.
The vehicle should first be:
Inspected.
A tire doesn't have to explode to be damaged.
A hard pothole impact can potentially cause:
Sidewall damage
Internal structural damage
Bulge or bubble
Cut
Pinch damage
Rapid pressure loss
Slow pressure loss
Tread or belt damage
The tire may still contain air.
That doesn't necessarily mean:
The tire is safe.
After a hard impact, inspect the tire when it is safe to do so.
Look at the sidewall.
If you see:
A bubble or bulge
the tire may have suffered internal structural damage.
A bulging tire should not be treated like a cosmetic issue.
It can potentially fail without much warning.
If you find a significant sidewall bulge:
Do not continue highway driving on that tire.
Arrange appropriate assistance.
You don't need to:
Press it.
Kick it.
or:
Test how firm it feels.
If the sidewall is visibly deformed:
Treat it as damaged.
The visible outer sidewall isn't necessarily the only area that can be damaged.
The inside portion of the tire may also have taken a significant impact.
A quick roadside visual inspection may not reveal every problem.
That's why:
“I looked at the tire and it seems fine”
doesn't guarantee there is no internal damage.
A pothole impact can potentially bend or crack a wheel.
Possible symptoms include:
Vibration
Air loss
Steering-wheel shake
Tire losing pressure
Vehicle pulling
Visible wheel deformation
Some wheel damage may be obvious.
Other damage may be difficult to see without:
Removing and inspecting the wheel.
A damaged alloy wheel may potentially develop a crack.
That can create:
Slow pressure loss
Sudden pressure loss
Recurring low-tire warning
If the tire keeps losing pressure after a hard pothole impact:
Don't assume:
The tire itself is the only possible problem.
The wheel should also be inspected.
A TPMS warning after a pothole impact deserves attention.
Reduce speed.
Find somewhere safe.
Inspect the affected tire when possible.
The warning may indicate:
Pressure loss.
Don't simply reset the warning and continue driving without determining why it appeared.
Suppose you're traveling straight.
But now the steering wheel sits noticeably:
Left
or:
Right.
Something may have changed in the:
Alignment
Steering geometry
Suspension geometry
Tire or wheel
Don't assume an alignment adjustment alone is the solution.
Have the vehicle inspected for:
Damage first.
A sudden steering pull after a pothole deserves attention.
Keep both hands on the steering wheel.
Reduce speed.
Avoid abrupt corrections.
Find somewhere safe to stop.
Potential causes can involve:
Tire pressure
Tire damage
Wheel damage
Alignment
Steering
Suspension
Other problems
If the pull is strong enough that you're struggling to maintain your lane:
Stop driving as soon as safely practical.
This is more concerning.
If after the impact the steering feels:
Loose
Unpredictable
Delayed
Wandering
Unstable
Different from normal
don't continue at highway speed.
A steering or suspension component may have been affected.
Get somewhere safe.
A pothole impact followed by suddenly heavy or binding steering should also be treated seriously.
Don't force the vehicle through normal driving.
Reduce speed.
Find somewhere safe.
Arrange inspection or towing when steering reliability is uncertain.
A new vibration immediately after hitting a pothole is useful information.
You may feel it through:
Steering wheel.
Seat.
Floor.
or:
Entire vehicle.
Possible causes can involve:
Tire damage
Bent wheel
Wheel balance change
Suspension damage
Steering damage
Other rotating components
Don't speed up to:
“See if it smooths out.”
Suppose:
At 30 mph, the vehicle feels slightly different.
At 45 mph:
The vibration increases.
At 55 mph:
The steering wheel begins shaking.
Don't continue accelerating to 70 mph.
The increasing vibration is giving you information.
Listen to the vehicle.
Slow down.
After an impact, some drivers think:
“I'll get back up to speed and see how it feels.”
That's not the safest way to test a potentially damaged:
Tire.
Wheel.
Steering system.
or:
Suspension system.
If the vehicle already feels different at lower speed:
Don't deliberately expose it to greater forces at highway speed.
A repeating:
THUMP — THUMP — THUMP
that increases with vehicle speed could indicate a rotating-component problem.
Possible causes can involve:
Tire
Wheel
Other damaged component
Get somewhere safe.
Don't keep driving until the thumping becomes:
Banging.
A pothole impact may potentially loosen or damage:
Splash shield
Underbody panel
Exhaust component
Wheel-well liner
Other component
If you hear scraping:
Get somewhere safe.
Don't crawl beneath the vehicle on the roadside.
Something may be hanging underneath.
Clunking after a severe impact may indicate something has:
Moved.
Broken.
Loosened.
or:
Been damaged.
Possible areas include:
Suspension
Steering
Wheel assembly
Underbody components
A new clunk immediately following a hard impact deserves inspection.
Grinding is another reason to take the situation seriously.
Possible causes may involve:
Wheel
Wheel bearing
Brake component
Suspension component
Something contacting a rotating part
Don't continue highway driving while hoping it wears itself smooth.
The suspension absorbs tremendous forces.
A severe pothole strike may potentially affect components such as:
Control arms
Ball joints
Tie rods
Struts
Shocks
Springs
Bushings
Steering knuckle
Other components
Some damage can alter:
Wheel alignment and vehicle stability.
Yes, a pothole can affect wheel alignment.
Possible symptoms include:
Vehicle pulling
Steering wheel off-center
Uneven steering response
Vehicle wandering
But remember:
Alignment should follow inspection.
If a component is bent or damaged:
Adjusting alignment without repairing the underlying problem isn't the correct solution.
If the affected corner begins:
Bouncing excessively
Sitting lower
Making noise over bumps
Feeling unstable
a suspension component may have been damaged.
Don't ignore a sudden change in ride behavior.
From a safe location:
Look at the vehicle from a distance.
Does one corner appear:
Lower than the others?
Does a wheel appear:
Tilted unusually?
Is the tire:
Too close to the wheel well?
Does anything look obviously out of position?
If so:
Don't continue driving.
A severe impact may also affect components beneath the vehicle.
Depending on vehicle design and impact location, vulnerable areas can include:
Oil pan
Transmission pan
Exhaust
Shields
Cooling components
Fuel-system components
Other underbody parts
That's why you should also pay attention to:
Fluid leaks.
Once you're safely stopped:
Look beneath the vehicle from a safe position.
Do not crawl underneath it.
Look for:
Fresh puddles
Active dripping
Fluid trail
Wet underbody components
If fluid is leaking significantly:
Don't continue driving until the source is identified.
If the pothole or road impact damaged the oil pan:
Engine oil may begin leaking.
If the oil-pressure warning appears:
Stop the engine.
Don't continue driving.
Loss of engine oil or oil pressure can cause catastrophic engine damage.
If you see coolant leaking or the engine-temperature warning appears:
Get somewhere safe.
Shut the engine down.
Do not open a hot pressurized cooling system.
Arrange assistance.
A strong fuel smell after a severe underbody impact deserves immediate attention.
Get safely stopped.
Shut the vehicle down.
Keep ignition sources away.
If you see a significant fuel leak:
Move people away from the vehicle.
Contact emergency services when appropriate.
If the vehicle begins driving differently:

Maintain control.
Be prepared for pulling or vibration.
Reduce speed gradually.
Unless traffic conditions require emergency braking.
Make controlled lane changes.
Especially if you're slowing significantly.
Move away from high-speed traffic.
Determine whether the vehicle is safe before continuing.
Unless you need emergency braking to avoid a collision:
Maintain control.
Ease off the accelerator.
Reduce speed.
Then move toward a safe stopping location.
If a tire or wheel has been damaged:
Abrupt vehicle inputs may make control more difficult.
The impact may startle you.
Don't immediately jerk the vehicle toward the shoulder.
Check:
Mirrors.
Blind spot.
Traffic position.
Then move over smoothly.
Look for:
Wide shoulder
Parking lot
Rest area
Highway exit
Emergency pull-off
Other location away from moving traffic
If the vehicle feels severely unstable:
Don't keep driving to find a more convenient location.
Take the first reasonably safe opportunity.
Before stepping outside:
Look at traffic conditions.
A damaged wheel can wait.
Your safety cannot.
Ask:
Is the shoulder wide?
Is traffic passing close by?
Am I near a blind curve?
Is there a guardrail?
Is there a protected area?
Is it safer to remain inside?
Don't stand next to moving traffic to inspect a tire.
If you're somewhere protected:
Perform a visual walk-around.
Look for:
TIRES
Flat tire
Low tire
Bulge
Cut
Missing tread
Obvious deformation
WHEELS
Visible bend
Crack
Unusual position
VEHICLE POSITION
One corner sitting low
Wheel sitting at unusual angle
UNDERBODY
From outside only:
Hanging parts
Fresh leaks
Scraping components
DASHBOARD
Check for:
TPMS warning
Oil-pressure warning
Temperature warning
ABS warning
Other new alerts
This deserves its own rule.
Don't crawl beneath a disabled vehicle on the side of the road.
Especially if:
Traffic is nearby
Ground isn't level
Vehicle isn't properly supported
You don't know what has been damaged
A roadside inspection should be:
Visual.
Not:
An under-car repair session.
If you have a tire-pressure gauge and can safely use it:
Compare tire pressure with the vehicle manufacturer's specification.
The recommended pressure is typically found on:
The driver's door-jamb placard
rather than simply using the maximum pressure printed on the tire sidewall.
If one tire has lost substantial pressure:
Don't return to highway speed.
If a tire loses air because of:
Sidewall damage
Wheel crack
Bead damage
Puncture
Other impact damage
adding air may only temporarily restore pressure.
Determine why it lost pressure.
You may inspect the vehicle and find:
No visible tire damage.
No leaks.
No obviously bent wheel.
No hanging components.
That's encouraging.
But it doesn't prove:
Nothing was damaged.
Internal tire damage and some steering or suspension damage may not be visible during a roadside walk-around.
Pay attention to how the vehicle behaves.
If:
No warnings are present
No visible damage exists
Tire pressure is normal
No leaks are visible
Steering feels normal
No vibration exists
No unusual noises occur
Vehicle remains stable
you may decide to continue cautiously and arrange inspection.
But if the vehicle:
Feels different
don't immediately accelerate back to highway speed.
Don't continue normal driving if:
🛑 Tire has a bulge
🛑 Tire is losing pressure
🛑 Wheel is visibly bent or cracked
🛑 Steering pulls strongly
🛑 Steering feels loose or unstable
🛑 Vehicle vibrates severely
🛑 Wheel sits at an unusual angle
🛑 You hear heavy clunking or grinding
🛑 A fluid leak is present
🛑 Oil-pressure warning appears
🛑 Engine begins overheating
🛑 Vehicle feels unsafe or unpredictable
That's when:
Towing may be the smarter choice.
A damaged vehicle may still:
Start.
Move.
Accelerate.
Steer.
Brake.
That doesn't necessarily mean:
It is safe at highway speed.
The better question is:
“Can I trust the tire, wheel, steering, suspension, and other affected systems at highway speed?”
If you don't know:
Don't gamble.
Even a mild new pull after a pothole should be inspected.
Maybe the alignment changed.
Maybe tire pressure changed.
Maybe a component moved.
The fact that the symptom is mild doesn't tell you the cause.
Avoid assuming.
Even if everything seems normal:
Consider inspecting the affected tire and wheel more carefully later.
A severe impact can sometimes create damage that becomes more noticeable afterward.
Over the next several drives, pay attention to:
Tire pressure
New vibration
Pulling
Uneven tire wear
New noises
Steering-wheel position
If you may need documentation for:
Insurance
Road-hazard coverage
Municipality claim
Repair records
photos can potentially help.
But:
Do not walk into traffic to photograph a pothole.
Vehicle damage is replaceable.
You aren't.
When safely parked, take pictures of:
Tire
Wheel
Vehicle position
Visible leak
Damaged underbody component if visible without crawling underneath
Dashboard warning lights
These can also help the repair provider understand what happened.
Provide:
Road or highway
Direction of travel
Nearest exit or mile marker
Shoulder or parking location
Year
Make
Model
Color
Tell them:
“I hit a large pothole and the vehicle started pulling.”
“The tire has a sidewall bulge.”
“The wheel appears bent.”
“The steering wheel is shaking.”
“The vehicle is leaking fluid after the impact.”
“One wheel looks like it's sitting at an angle.”
This helps determine the type of assistance needed.
Explain:
What happened before the symptoms began.
For example:
“I hit a pothole with the right-front wheel at approximately 50 mph.”
Then describe:
What changed immediately afterward.
Such as:
“The vehicle now pulls right.”
“The steering wheel is off-center.”
“There's a vibration above 40 mph.”
“The TPMS light came on.”
“I hear a clunk from the front when turning.”
“There's fluid beneath the vehicle.”
That is much more useful than saying:
“I need an alignment.”
A good request is:
“I hit a severe pothole and the vehicle started pulling afterward. Please inspect the tire, wheel, steering, and suspension for damage and check the alignment.”
That approach focuses on:
Finding the cause.
Not simply adjusting around potential damage.
After hitting a severe pothole:
✓ Stay calm
✓ Keep both hands on the wheel
✓ Pay attention to what changed
✓ Ease off the accelerator if something feels wrong
✓ Avoid sudden steering
✓ Avoid unnecessary hard braking
✓ Turn on hazards when appropriate
✓ Find somewhere safe to stop
✓ Check for tire-pressure warnings
✓ Look for tire bulges or damage
✓ Look for obvious wheel damage
✓ Look for fluid leaks
✓ Check whether one corner sits unusually low
✓ Listen for thumping, scraping, grinding, or clunking
✓ Don't crawl underneath the vehicle roadside
✓ Don't assume pulling automatically means alignment
✓ Don't immediately return to highway speed if something feels different
✓ Tow the vehicle when its safety is uncertain
After a hard pothole impact:
Maintain your lane.
Notice pulling, vibration, or steering changes.
Notice thumping, grinding, scraping, or clunking.
Check warning lights.
Reduce speed if something feels wrong.
Find a safe stopping location.
Inspect tires, wheels, vehicle position, and visible leaks when safe.
Don't assume it only needs an alignment.
Is the vehicle truly behaving normally?
If the answer is uncertain:
Don't return to highway speed.
Hitting a pothole doesn't automatically mean your vehicle has suffered serious damage.
But if it begins:
PULLING
SHAKING
VIBRATING
CLUNKING
SCRAPING
or:
LEAKING
immediately afterward:
PAY ATTENTION.
A pothole can potentially damage more than the alignment.
It may affect:
TIRES.
WHEELS.
STEERING.
SUSPENSION.
UNDERBODY COMPONENTS.
and other parts of the vehicle.
Don't automatically order an alignment.
Don't accelerate back to 70 mph to test the car.
Don't keep driving on a visible tire bulge.
And don't ignore a new fluid leak.
Instead:
Reduce speed.
Get somewhere safe.
Inspect what you safely can.
Have the vehicle properly evaluated.
And if you're uncertain whether a damaged component can safely handle highway speed:
TOW IT.
A tow is cheaper than turning a damaged tire, wheel, or suspension component into:
A loss-of-control situation.
Once you're safely away from moving traffic, FixFlowIQ can help you connect with vetted automotive professionals.
