Missouri requires the option of curbside voting for anyone with a disability. If there's not a button at the voting site or phone number, voters can send someone in to advise the election judges that someone needs a ballot brought to the vehicle. Note that anyone still in line at 7 pm will be allowed to vote.

St. Louis County: The BOE headquarters at 725 Northwest Plaza Drive in St. Ann works best for curbside voting, but it's also available on request at 230 polling places on Election Day. 

St. Louis City: All City satellite locations have curbside voting: Voting Locations (Polling Places). Voters should look for a sign with a buzzer. Choose from any of 72 polling places on Election Day. 

St. Charles County: Curbside voting is available at the Election Authority Headquarters (397 Turner Blvd in St. Peters). 

Franklin County: Park in the marked space outside the county clerk’s office at 400 E. Locust in Union, then call the number stated on the sign.
