Introduction
Speed bumps are everywhere in Sutton and Cheam — outside schools, on residential streets, and throughout traffic-calmed neighbourhoods. While they play an important role in road safety, repeated exposure to speed bumps can quietly damage your car over time.
At Cheam Motors, many vehicles come in with suspension, exhaust, and alignment issues caused not by potholes or accidents, but by daily speed bump driving. This article explains how Sutton’s speed bumps affect your vehicle and how to reduce long-term damage.
Why Speed Bumps Are So Common in Sutton
Local councils have installed speed humps to reduce speeding near:
- Schools and nurseries
- Residential streets
- Pedestrian-heavy areas
- Narrow neighbourhood roads
For drivers who use the same routes daily, this means crossing dozens of speed bumps every week — often without realising the mechanical impact.
1. Suspension Wear from Repeated Impact
Speed bumps compress your suspension every time you cross them. Over time, this leads to:
- Worn shock absorbers
- Sagging or broken springs
- Perished suspension bushings
Common signs include knocking noises, bouncy rides, and uneven handling.

2. Exhaust System Damage
Low-speed humps are a major cause of:
- Scraped exhaust pipes
- Damaged heat shields
- Loose exhaust mountings
Cars with low ground clearance are especially vulnerable. Exhaust issues are frequently flagged during MOT tests.

3. Wheel Alignment Issues
Even when taken slowly, uneven speed bumps can knock wheels out of alignment over time.
Symptoms include:
- Steering pulling left or right
- Crooked steering wheel
- Rapid or uneven tyre wear

4. Increased Tyre Stress
Speed bumps force tyres to deform repeatedly, especially when crossed at an angle or with uneven pressure. This contributes to:
- Sidewall stress
- Accelerated tread wear
- Reduced grip in wet conditions
Combined with Sutton’s urban kerbs and tight parking, tyre damage becomes more likely.
5. Steering Component Wear
Repeated suspension compression also affects steering parts such as:
- Track rod ends
- Ball joints
- Anti-roll bar links
These components are safety-critical and commonly fail MOT inspections when worn.
Why Speed Bump Damage Often Goes Unnoticed
Unlike pothole strikes, speed bump damage is gradual. Drivers often assume symptoms are “normal ageing” rather than cumulative damage from daily routes.
Because there’s no single incident, issues are often ignored until:
- An MOT failure
- A loud knocking noise
- Uneven tyre wear becomes obvious
How Speed Bumps Affect MOT Results
While speed bumps themselves aren’t tested, the damage they cause is.
Common MOT failure items linked to speed bump wear include:
- Suspension faults
- Exhaust leaks or loose mountings
- Tyre condition issues
Booking a full service or interim service before your MOT helps catch these problems early.
Practical Tips for Sutton Drivers
- Approach speed bumps slowly and straight
- Avoid braking sharply while crossing
- Keep tyres correctly inflated
- Listen for new rattles or knocks
- Have suspension checked annually
If your daily route includes multiple speed humps, preventive maintenance is essential.

At least once a year, or sooner if knocking or handling changes occur.
