What to Check After Hitting a Pothole

Hitting a pothole hard enough to genuinely worry about is an unfortunately common experience on UK roads, and knowing exactly what to check afterwards helps you catch damage before it develops into something more serious or, worse, becomes a safety issue on your next journey.

Why potholes cause genuine damage

A hard pothole impact delivers a sudden, concentrated shock to the wheel, tyre and suspension components, quite different from the gradual wear these parts are designed to handle through normal driving. This sudden impact can bend a wheel, damage a tyre’s internal structure, or knock suspension components and wheel alignment out of specification, sometimes without any immediately obvious external sign.

The immediate check, if it’s safe to do so

If you’ve hit a significant pothole and it’s safe to pull over, a quick visual check is worthwhile before continuing your journey. Look at the affected tyre for any obvious bulge, cut or deformity, check for any fluid leaking from underneath the car, and listen for any new, unusual noise as you pull away, all of which can indicate damage serious enough to need immediate attention rather than continuing to drive.

Checking the tyre itself for damage

Tyres are often the first point of contact and can suffer several types of pothole-related damage. A sudden impact can cause an immediate puncture, but it can also cause a sidewall bulge, where the internal structure has been damaged without the tyre losing air immediately, and a bulging tyre is genuinely dangerous, at real risk of sudden failure, and should be replaced rather than driven on.

• Check for visible bulges or deformities on the tyre sidewall
• Look for cuts, gouges or other visible damage to the tyre
• Check tyre pressure, since impact damage can cause a slow leak
• Inspect the wheel rim for visible bends or cracks
• Listen for new noises, particularly from the affected wheel

Checking the wheel for damage

Beyond the tyre itself, the wheel rim can suffer a visible bend, dent or crack from a hard pothole impact, sometimes obvious to the eye and sometimes subtle enough to need a closer inspection. A damaged wheel rim can affect how the tyre seats against it, potentially causing an air leak, and in more serious cases can compromise the wheel’s structural integrity.

Signs suspension has been affected

Suspension damage from a pothole isn’t always immediately obvious, and symptoms can develop gradually over the following days rather than appearing instantly. A car that feels noticeably different to drive, perhaps bouncier, less stable through corners, or pulling slightly to one side, is worth investigating, since this kind of change often points toward a suspension component that’s been damaged or knocked out of its intended position.

How wheel alignment gets knocked out by potholes

A hard impact can knock wheel alignment, sometimes called tracking, out of specification even without causing any other visible damage. Misaligned wheels cause the car to pull slightly to one side, and over time cause uneven, accelerated tyre wear if left uncorrected. This is a genuinely common and often overlooked consequence of a significant pothole impact, worth checking even if nothing else seems obviously wrong.

Listening for unusual noises after the fact

In the days following a hard pothole impact, pay attention to any new noises that weren’t present before: a clunking sound over bumps, a knocking noise when turning, or a rattling that wasn’t there previously. These noises often indicate a component has been loosened or damaged by the impact, and while the car might still feel driveable, these are genuine warning signs worth having properly investigated.

Why some damage only becomes apparent over time

Not every consequence of a pothole impact is immediately obvious. A suspension bush that’s been slightly damaged might continue functioning adequately for a period before finally failing, and a slow puncture from tyre damage might take days to become noticeable. This delayed presentation is exactly why it’s worth keeping an eye on the car’s behaviour for a week or two after any significant pothole impact, not just checking once immediately afterward.

What a proper post-pothole inspection covers

A thorough professional check after a significant pothole impact covers the tyre and wheel for visible and structural damage, the suspension components for any sign of damage or excessive play, and wheel alignment to confirm it’s still within specification. This level of inspection catches issues that might not be obvious from the driver’s seat, giving you genuine confidence the car is safe to continue driving.

Why West Yorkshire’s roads see particular pothole risk

Bradford and the surrounding West Yorkshire area, like much of the UK, experiences a genuine seasonal pattern of pothole development, particularly worsening after a hard winter of freeze-thaw cycles that expand and crack road surfaces already weakened by traffic. Being aware that pothole risk increases at certain times of year, particularly late winter and early spring, is worth factoring into how alert you stay for potential impacts and subsequent damage.

Reporting a dangerous pothole

If you’ve hit a pothole that seems genuinely dangerous, it’s worth reporting it to the relevant local authority, both to protect other road users and to potentially support a compensation claim if the pothole subsequently causes damage to your car. Gov.uk’s pothole reporting service provides a straightforward way to flag a dangerous pothole for repair.

Claiming for pothole damage

In some circumstances, it’s possible to claim compensation from the relevant council for pothole damage, particularly if the pothole was previously reported and not repaired within a reasonable timeframe. Successful claims generally require proper documentation, including photos of the pothole and damage, and a clear record of when and where the impact occurred, so it’s worth gathering this evidence promptly after any significant impact.

Getting shock absorbers checked after a significant impact

Shock absorbers, responsible for controlling how the suspension responds to bumps and impacts, can be damaged by a hard pothole strike, sometimes developing a leak or internal damage that reduces their effectiveness without an immediately obvious external sign. A shock absorber replacement, carried out promptly if damage is confirmed, restores the car’s intended handling and ride quality, and prevents the knock-on wear that a damaged shock absorber can cause to other suspension components over time.

When to get checked versus when to simply monitor

Not every pothole impact requires an immediate professional check, a very minor jolt on an otherwise well-maintained road might genuinely cause no lasting damage. But any impact hard enough to make you wince, cause an immediate noise, or noticeably jolt the car warrants at least the checks covered in this guide, and a proper professional inspection if anything feels different about how the car drives afterward.

Why speed and impact angle both affect the severity of damage

The severity of pothole damage depends on more than just the pothole’s size, the speed you were travelling at and the angle at which the wheel struck the edge both play a significant role. A pothole hit squarely at low speed might cause relatively little harm, while the same pothole struck at an angle or at higher speed can transfer considerably more force into the wheel and suspension, increasing the likelihood of genuine damage.

How run-flat and low-profile tyres are affected differently

Cars fitted with low-profile tyres, which have less sidewall depth between the wheel rim and the road, are generally more vulnerable to pothole damage, since there’s less cushioning material to absorb the impact before it reaches the wheel itself. Run-flat tyres, designed to be driven on briefly even after losing pressure, can also mask the early signs of impact damage, since they don’t necessarily deflate immediately the way a standard tyre would, making a proper check after any hard impact particularly important on these tyre types.

Why documenting the damage helps with any potential claim

If you suspect a pothole has caused genuine damage, taking photos of both the pothole itself and any visible damage to your car shortly afterward creates useful documentation, should you decide to pursue a compensation claim from the relevant council. Noting the date, location and circumstances of the impact while it’s fresh in your memory also strengthens any subsequent claim considerably compared to relying on memory alone weeks later.

The cost of ignoring early pothole damage

Suspension and steering components work together as a system, and damage to one part often places additional strain on neighbouring components as they compensate for the fault. A relatively minor, inexpensive repair caught early can develop into a considerably more extensive and costly job if left unaddressed, as the original damage gradually affects other parts of the suspension and steering system that were previously working normally.

Getting peace of mind with a mobile inspection

Rather than worrying about whether a hard pothole impact has caused lasting damage, a mobile mechanic can come to your home or workplace to carry out a proper post-impact inspection, checking tyres, wheels, suspension and alignment without you needing to find time to visit a garage. This convenience makes it considerably easier to get any concern properly checked promptly, rather than putting it off and risking further damage in the meantime.

Why insurance rarely covers everyday pothole damage

It’s worth being aware that standard motor insurance policies don’t automatically cover pothole damage in the way they might cover an accident, and claiming through your own insurer for this kind of damage can affect your no-claims record, since it’s generally processed in a similar way to any other claim. This is exactly why pursuing compensation directly from the responsible local authority, where the pothole was known and not repaired promptly, is often the more sensible route for genuine pothole-related damage.

How shock absorbers actually work and why impacts affect them

Shock absorbers control the speed at which your suspension springs compress and extend, converting the kinetic energy of a bump into heat through a hydraulic damping mechanism inside the unit. A hard, sudden impact like a pothole strike can exceed the design limits of this mechanism momentarily, potentially causing an internal seal to fail or the damping fluid to leak, gradually reducing the shock absorber’s effectiveness even if it continues functioning at a reduced level rather than failing outright.

Why replacing shock absorbers in pairs is usually recommended

Similar to tyres, shock absorbers are generally recommended to be replaced in pairs, front or rear, rather than replacing just the single damaged unit. This is because shock absorbers naturally wear over time even without impact damage, meaning the undamaged unit on the opposite side is likely also partway through its useful life, and pairing a brand new shock absorber with a significantly more worn one can create an imbalance in how the suspension responds on each side of the car.

Why acting on a suspected steering or suspension issue matters legally too

Beyond the practical safety concerns, driving with a known suspension or steering defect can also have legal implications, since these are systems specifically assessed during an MOT test and a genuine fault can result in a test failure or, in more serious cases, a vehicle being deemed unroadworthy. Addressing a suspected issue promptly, rather than continuing to drive and hoping it holds until the next scheduled test, avoids both the safety risk and any potential legal complication.

What drivers can reasonably do themselves versus what needs a professional

A visual check for obvious tyre bulges, fluid leaks, or a bent wheel rim is something most drivers can reasonably do themselves after a hard pothole impact. However, properly assessing suspension component condition, measuring wheel alignment accurately, and identifying more subtle internal damage genuinely requires professional equipment and experience, which is exactly why a basic visual check is a useful first step but shouldn’t be treated as a substitute for a proper inspection when something feels genuinely different about the car. Taking those few extra minutes after a hard impact, rather than simply carrying on and hoping for the best, is a genuinely small price for the peace of mind it buys. and it means driving on with genuine confidence rather than a nagging doubt in the back of your mind.
