Clean Vehicles Save Lives: Health and Safety for Everyone
My Message to People Around the World
I am sharing my true story because I want people around the world to understand that keeping a vehicle clean is not only about appearance. It is also about health, safety, respect and responsibility.
This message applies to every type of vehicle:
Personal and solo vehicles
Family vehicles
Construction trucks
Company vans
Taxis and rideshare vehicles
Delivery vehicles
School or childcare vehicles
Vehicles used to transport workers
Vehicles carrying paint, stain, tools or building materials
A vehicle is a small, enclosed space where people may spend many hours breathing the same air. Dust, smoke, mould, food waste, perfume, air fresheners, paint residue, fence stain, wood dust, metal dust, oil, fuel vapours and exhaust may collect inside.
Not everyone will react in the same way. One person may notice only an unpleasant smell, while another may develop burning eyes, throat irritation, coughing, headache, dizziness, weakness, nausea or breathing difficulty.
The World Health Organization explains that short-term exposure to high levels of airborne particles can reduce lung function, aggravate asthma and contribute to respiratory infections. Long-term exposure to fine particles is associated with diseases including heart disease, stroke, chronic lung disease and cancer.
What Happened to Me
I live with a traumatic brain injury, also called TBI, and long-term post-traumatic concussion symptoms.
My original TBI was caused by physical trauma to my head many years ago. An unclean vehicle did not cause my original brain injury.
However, I already live with headaches, weakness and sensitivity. People with TBI may also experience dizziness, nausea, fatigue, concentration problems and sensitivity to light, noise or other environmental conditions.
I entered someone's vehicle that had not been properly cleaned. There was visible dirt and dust inside, along with strong odours. Someone's vehicles may contain wood dust, paint residue, fence stain, dirty tools, oil, old food or other materials.
After being inside the vehicle, I began feeling seriously unwell.
My eyes felt like they were burning. My throat became painful and irritated. I developed a severe headache. My back and body were painful, and I felt extremely weak. My ears and body felt very hot. My heart was beating quickly, and sometimes it felt difficult to breathe.
My temperature reportedly reached approximately 40.4°C.
I tried to explain that I was becoming sick before my symptoms became worse. I knew that something was wrong with my body.
Sadly, not everyone believed what I was experiencing, but I am thankful for those who believed me and stood by my side.
That experience taught me an important lesson.
This is why I want people to understand:
Believe a person when they warn you that they are becoming sick.
Do not wait until the person collapses before offering help.
A person should not have to prove that they are suffering before receiving support.
A Body Temperature Around or Above 40°C Is Serious
A temperature near or above 40°C can be a sign of a serious medical emergency, especially when it happens with confusion, fainting, seizures, severe weakness or loss of consciousness.
Heat stroke requires immediate medical treatment. Fast cooling and emergency care can reduce the risk of complications.
However, a high body temperature should not automatically be blamed only on vehicle dirt or a strong smell.
Possible causes may include:
Heat stroke
Infection
Medication effects
Dehydration
Inflammatory illness
Another serious medical condition
Only qualified healthcare professionals can investigate and determine the cause.
The important point is that a temperature around or above 40°C must never be dismissed. If the person is confused, fainting, having difficulty breathing, experiencing chest pain or rapidly becoming worse, contact local emergency services immediately.
Can an Unclean Vehicle Make Someone Sick?
An unclean vehicle may contribute to symptoms when it contains specific hazards. However, there is no single worldwide percentage showing how many illnesses are caused by vehicles that have not been cleaned.
The term “dirty vehicle” can describe many different conditions.
One vehicle may contain only food crumbs and ordinary soil. Another may contain:
Mould
Cigarette smoke
Diesel exhaust
Wood dust
Concrete or silica dust
Paint solvents
Fuel vapours
Strong perfume
Animal allergens
Leaking chemicals
The level of risk depends on the substance, concentration, ventilation, temperature, length of exposure and the person’s health.
It would be inaccurate to say that every dirty vehicle directly causes infection, cancer, high white blood cells or TBI.
However, specific contaminants can irritate the eyes, throat and lungs, trigger symptoms, worsen medical conditions and create serious short-term or long-term health risks.
Wood Dust and Construction Vehicles
Construction trucks can collect wood dust after cutting, drilling, sanding or transporting lumber.
The dust may remain on:
Seats
Carpets
Floor mats
Clothing
Tools
Air vents
Personal belongings
Breathing airborne wood dust may irritate the eyes, nose, throat and lungs. Some people may develop coughing, wheezing, allergy symptoms or breathing discomfort.
Long-term workplace exposure to certain wood dust is also recognized as a cancer hazard. This does not mean that entering one dusty vehicle automatically causes cancer. Cancer risk depends on the type of material and the amount, frequency and duration of exposure.
Workers should avoid shaking dusty clothes or using compressed air inside the passenger compartment because this may send particles back into the air.
Dusty tools and work clothing should be separated from passengers whenever possible.
Suitable vacuuming and damp-cleaning methods may help remove dust without spreading it again.
Paint, Fence Stain and Chemical Vapours
Work vehicles may carry paint, fence stain, adhesives, solvents, oils, fuel and cleaning products.
Some products release vapours that may irritate the eyes, nose, throat or lungs. Depending on the substance and exposure level, a person may also experience headache, dizziness, nausea or breathing discomfort.
Chemical containers should always be:
Closed securely
Kept upright
Stored in their original labelled containers
Protected from spills
Secured so they cannot move
Transported according to manufacturer instructions
Kept away from children
Do not use the passenger compartment as permanent chemical storage.
A closed vehicle can become very hot. Heat may increase evaporation, pressure inside containers and the strength of odours.
Never mix cleaning chemicals. Never leave leaking fuel, paint, stain or solvents inside a vehicle used to transport people.
Diesel Exhaust and Cancer Risk
Diesel exhaust should not enter the passenger compartment.
The International Agency for Research on Cancer classifies diesel engine exhaust as carcinogenic to humans and reports evidence connecting occupational exposure with an increased risk of lung cancer.
This does not mean that one brief smell of diesel automatically causes cancer. Cancer risk normally relates to the amount and duration of exposure.
However, repeated exhaust exposure should never be ignored.
Do not leave vehicles running inside closed garages. If exhaust enters the cabin, stop using the vehicle and arrange a professional inspection.
Mould, Dust and Throat Problems
Mould, dust, smoke and chemical vapours may cause:
A sore or burning throat
Coughing
Wheezing
Congestion
Burning or watery eyes
Skin irritation
Asthma symptoms
However, throat irritation is not automatically a throat infection.
Most common throat infections are caused by viruses or bacteria. Ordinary vehicle dirt does not directly create a viral or bacterial infection.
Air pollution and airborne particles can irritate the respiratory system and may aggravate asthma or other lung conditions.
A person should seek medical advice when throat symptoms happen with a high fever, difficulty breathing, difficulty swallowing, swelling, dehydration or worsening pain.
White Blood Cells and Infection
White blood cells are part of the immune system. Doctors may check them through a blood test called a complete blood count.
A high white blood cell count can have many possible causes, including:
Infection
Inflammation
Physical stress
Injury
Medication effects
Immune-system conditions
Other medical problems
It is not medically accurate to say that a dirty vehicle directly causes white blood cells.
If blood results are abnormal after a person becomes sick, a healthcare professional must review the symptoms, physical examination, exposure history and other test results.
The person’s symptoms should be believed and taken seriously, but the cause should not be claimed as certain unless it has been medically investigated.
A Dirty Vehicle Does Not Cause a New TBI
TBI is caused by physical trauma, such as a blow, bump, jolt, fall or collision.
Dust, mould, perfume, smoke or chemical odours do not directly cause a new TBI.
However, someone who already lives with TBI may experience headaches, dizziness, nausea, fatigue, concentration problems and sensory sensitivity. Strong odours, uncomfortable air, extreme heat and physical stress may make the person feel worse or make existing symptoms more difficult to manage.
Every person with TBI is different.
Be Careful What You Say
One of the hardest parts of becoming sick is when people refuse to believe you.
Please never say:
"You are fine."
"Stop being a diva."
"You are overreacting."
"It is only dust."
"It is only a smell."
"It is all in your head."
"Everyone else is fine."
"You are just being dramatic."
These comments can be hurtful and may delay someone from receiving help.
Do not judge someone simply because they look normal.
Not every illness or medical condition is visible.
Be careful before criticizing or making assumptions.
If you ignore someone's warning, tell them to "stop complaining," or pressure them to stay inside the vehicle, their condition may become much worse before anyone realizes how serious it is.
Instead of judging, choose compassion.
Instead of arguing, choose to listen.
Instead of saying, "You are fine," ask, "How can I help?"
Instead of saying, "Stop being a diva," ask, "Do you need fresh air or medical help?"
You are not expected to diagnose another person's illness.
That is the job of doctors and other healthcare professionals.
Your responsibility is to take the person's symptoms seriously, help them move to a safer place and encourage them to seek medical care when needed.
Your words matter.
Your attitude matters.
Your kindness matters.
Do not say:
“It is only in your head.”
“Other people feel fine.”
“You are exaggerating.”
“It is only dust.”
“You are too sensitive.”
Instead, say:
“I believe that you feel sick.”
“Let us get you out of the vehicle.”
“Do you need medical help?”
“What symptoms are you feeling?”
“I will stay with you.”
Believe the Warning Before the Attack Becomes Worse
Some people can recognize early warning signs because they have experienced similar symptoms before.
They may notice:
Burning eyes
Throat irritation
A severe headache
Dizziness
Weakness
Nausea
A racing heartbeat
Breathing discomfort
Confusion
Feeling unusually hot
A feeling that a serious attack or reaction is beginning
When someone gives an early warning, listen immediately.
You do not need to know the final diagnosis before helping.
You do not have to decide whether the cause is an allergy, asthma, infection, chemical irritation, heat illness, migraine or TBI symptom flare before moving the person to safety.
The correct first response is to stop the possible exposure and help the person obtain medical attention.
How Long Can Recovery Take?
There is no single recovery time because it depends on what caused the symptoms and how severely the person was affected.
Recovery can depend on:
The substance involved
The length and amount of exposure
Whether the person experienced heat exhaustion or heat stroke
Whether there is an infection
Whether the person has asthma or allergies
Whether the person already lives with TBI or another health condition
How quickly they received medical care
Whether the exposure caused complications
Whether the person continues to be exposed
Mild Eye, Nose or Throat Irritation
Mild irritation may begin improving after the person leaves the contaminated area and reaches fresh air.
Some people may feel better within several hours. For others, coughing, throat irritation, headaches or tiredness may continue for a few days.
Symptoms that continue, worsen or return should be assessed by a healthcare professional.
Allergic or Asthma Symptoms
Mild allergy symptoms may settle within hours or days after the trigger is removed.
Asthma symptoms can last longer and may require prescribed medication or emergency treatment. Severe wheezing, chest tightness or breathing difficulty requires urgent medical attention.
Heat Exhaustion
People with uncomplicated heat exhaustion may require at least one or two days to feel normal again. Recovery can take longer when dehydration is severe or the person was close to developing heat stroke.
A person should not immediately return to heavy work, hot environments or intense physical activity without medical guidance.
Heat Stroke
Heat stroke is much more serious. Recovery may take a week or longer, and severe cases can require hospital treatment and extended recovery.
Heat stroke may affect the brain, kidneys, liver, heart and muscles. Some people can have lasting complications, so medical follow-up is important.
A person who reportedly had a body temperature above 40°C should ask their healthcare provider when it is safe to return to work, driving or physical activity.
Infection
Recovery from a throat or respiratory infection depends on whether the infection is viral, bacterial or caused by another condition.
Some mild viral illnesses improve within several days, while others may take one or two weeks. Bacterial infections may require prescribed treatment.
A healthcare professional must determine whether an infection is present.
TBI and Post-Concussion Symptoms
Recovery from a new mild concussion often takes days or weeks for many people, but some experience symptoms for months or longer.
For someone who has lived with TBI for years, symptoms triggered or worsened by heat, illness, poor sleep, stress or environmental discomfort may not follow a predictable timeline.
The person may need:
Extra sleep and rest
Reduced screen time
A quiet environment
Less exposure to bright light
Regular meals and fluids
Medical follow-up
Temporary changes at work
A gradual return to activities
Recovery should not be rushed. Returning too quickly to an unsafe vehicle, extreme heat or heavy work may make symptoms worse.
When Recovery Is Taking Longer
Medical follow-up is important when symptoms continue for more than a few days or interfere with normal life.
Seek further medical assessment for:
Continuing fever
Severe or worsening headache
Ongoing dizziness
Persistent throat pain
Repeated vomiting
Ongoing fast heartbeat
Breathing problems
Confusion
Extreme weakness
New vision problems
Difficulty returning to work or regular activities
Recovery is not the same for everyone. A person should not be criticized because they need more time than someone else.
What to Do Immediately When Someone Becomes Sick
When someone says a vehicle is making them sick:
Stop the vehicle safely.
Help the person leave the vehicle.
Move them to clean, cool air.
Keep them away from the suspected contaminant.
Ask what symptoms they are experiencing.
Contact local emergency services for severe or rapidly worsening symptoms.
Do not leave a confused, faint or seriously ill person alone.
Tell healthcare workers about possible dust, smoke, exhaust, heat or chemical exposure.
Keep the product label available when it is safe.
Do not force the person to return to the vehicle.
Seek emergency help for:
Severe breathing difficulty
Chest pain
Confusion
Fainting
Seizures
Blue or grey lips
Suspected carbon monoxide exposure
A body temperature around or above 40°C with confusion
Symptoms that rapidly become worse
Protecting Children
Children may be more vulnerable to air pollution because their lungs and bodies are still developing.
Air pollution exposure is associated with respiratory infections, aggravated asthma and reduced lung function.
Children may not always be able to explain exactly how they feel. Adults should watch for:
Coughing
Wheezing
Trouble breathing
Burning or watery eyes
Unusual tiredness
Headache
Nausea
Changes in behaviour
Keep family and childcare vehicles smoke-free and vape-free.
Clean child car seats only according to the manufacturer’s directions. Strong chemicals or incorrect washing may damage safety materials.
Never leave a child, older adult, person with a disability or animal alone inside a parked vehicle.
Worldwide Vehicle Safety Checklist
To keep vehicles cleaner and safer:
Remove garbage and food waste regularly.
Vacuum seats, carpets, floor mats and cargo areas.
Clean construction dust after each shift or project.
Use damp-cleaning methods when appropriate.
Clean spills immediately.
Keep chemicals separate from passengers.
Secure paint, stain, fuel and tools.
Never mix cleaning chemicals.
Maintain the ventilation and air-conditioning systems.
Replace cabin air filters according to manufacturer instructions.

Do not smoke or vape inside vehicles.
Provide fresh air, water and cooling during hot weather.
Do not use an unclean or contaminated vehicle until the hazard is removed.
Frequently Asked Questions
Can an unclean vehicle make someone sick?
Yes. Dust, mould, smoke, exhaust, chemical vapours, fragrance and heat may contribute to irritation or serious symptoms. The actual cause may require medical investigation.
Can a dirty vehicle cause TBI?
No. A new TBI is caused by physical trauma. However, someone who already has TBI may experience worsening headaches, dizziness, fatigue or sensory problems in an uncomfortable environment.
Can vehicle dust cause throat pain?
Yes. Dust may irritate the throat. However, throat irritation does not automatically mean there is an infection.
Can an unclean vehicle raise white blood cells?
Not directly. An abnormal white blood cell count may be caused by infection, inflammation, stress or other medical conditions. A healthcare professional must determine the cause.
Can construction dust cause cancer?
Repeated or long-term exposure to certain hazardous dusts can increase cancer risk. This does not mean that every dusty vehicle causes cancer.
Is a temperature over 40°C dangerous?
Yes. A very high temperature, especially with confusion, fainting, seizures or loss of consciousness, may be a medical emergency.
How long does recovery take?
Mild irritation may improve within hours or days. Heat exhaustion may require one or two days or longer. Heat stroke may require a week or much longer, especially when complications occur.
TBI-related symptoms may continue for days, weeks, months or longer. A healthcare professional should guide recovery.
Should we believe someone who says an attack is beginning?
Yes. Take the warning seriously. Help them leave the possible exposure and obtain medical care.
Should someone immediately return to the same vehicle?
Not until the suspected hazard has been removed and the vehicle has been safely cleaned or inspected.
How often should a construction truck be cleaned?
Visible dust, spills, waste and chemical residue should be removed promptly. A heavily used work vehicle may require cleaning after every shift or project.
Conclusion: Believe the Person and Allow Time to Recover
I am sharing my true story because I do not want another person to suffer while their warning is ignored.
When I said I felt sick, I needed people to listen before my symptoms became severe.
It is not fair to dismiss someone because other passengers feel fine. Every person has a different body, medical history and level of sensitivity.
A dirty vehicle does not automatically cause TBI, infection, abnormal white blood cells or cancer.
Medical professionals must investigate and determine the cause.
However, construction dust, mould, smoke, chemical spills, exhaust and extreme heat are real health and safety concerns.
You do not need a final diagnosis before helping someone.
Believe the person.
Help them leave the vehicle.
Move them to fresh, cool air.
Contact emergency services for serious symptoms.
Keep the vehicle clean and remove possible hazards.
Allow the person enough time to recover.
Do not force them to return to work, drive or enter the same vehicle before they are medically ready.
A person should not have to collapse before receiving support. Clean vehicles, quick action, proper recovery time and respect for health warnings can reduce suffering and may help save a life.
