Cars are small spaces and when the windows are closed, SARS-CoV-2 (in fine aerosol particles) accumulates in the car’s cabin. Cracking one window open just 3 inches can help limit the COVID-19 spread.
Along with keeping windows open, here’s how you can protect yourself:
Clean and disinfect surfaces
Clean and disinfect frequently touched surfaces regularly (for example, the steering wheel, gear shift, door frame/handles, windows, radio/temperature dials, and seatbelt buckles). When using parking meters and pay stations, consider using alcohol wipes to disinfect surfaces or use hand sanitizer contain-ing at least 60% alcohol after use. Wash hands with soap and water for at least 20 seconds as soon as it is possible.
Practice social distancing
Consider limiting the number of passengers in the vehicle to only those necessary (for example, choose one or two family members who are not at higher risk for severe illness to run the essential errands).
Improve ventilation
Improve the ventilation in the vehicle if possible (for example, open the windows or set the air ventilation/air conditioning on non-recirculation mode).
In general, the more closely you interact with others and the longer that interaction, the higher the risk of COVID-19 spread. If transportation is part of your job, see additional resources on how to protect yourself from COVID-19 at work at www.cdc.gov.
