YOUR CAR AND ALLERGY: HOW TO DRIVE
If you are sensitive to vehicle exhaust fumes, you can adapt the way you drive in order to help yourself. Keep windows closed as much as you can. Unless you have a car with a re-circulating air system, do not use heating and fan unless you have to, and keep vents closed unless you really need ventilation. A sun-roof can be useful for ventilation – it draws air in and out of the car, directly away from your face.
If the car gets too cold, or too hot, or condensation develops, use the ventilation and heating system in short intense bursts, then close it down again. Shut off if you have to wait in heavy traffic.
Hang back from the vehicle ahead – especially in busy or stationary traffic – do not stop close to someone else’s exhaust, allowing fumes to be drawn directly into your car. Leave as much space as you can. Select a route, or a time, to drive that avoids traffic queues, or sitting stationary at junctions.
When filling your vehicle with fuel, keep windows and vents closed so that fumes from the pumps do not get into the vehicle. If you can find one, go to a service station where someone will serve you, rather than to a self-service garage.
Avoid car journeys in very hot weather if you are very sensitive to vehicle exhausts, or chemical vapours from materials. Materials in cars heat up and give off more vapour in hot weather. It is also impossible to keep windows closed. Only do essential journeys when it is extremely hot, and travel at a cooler time of day if you can. Go earlier to or later from work if possible.
If you are extremely sensitive, try wearing a face mask or use a car filter. If you cannot afford a filter, hanging damp cloths over air vents will reduce the amount of residual vapours which pass through.
