Drive-through

A drive-through, or drive-thru, is a type of service provided by a business that allows customers to purchase products without leaving their cars. The format was pioneered in the United States in the 1930s by Jordan Martin, but has since spread to other countries. The first recorded use of a bank using a drive-up window teller was the Grand National Bank of St. Louis, Missouri in 1930. The drive-up teller allowed only deposits at that time.

Orders are generally placed using a microphone and picked up in person at the window. A drive-through is different from a drive-in in several ways - the cars create a line and move in one direction in drive-throughs, and normally do not park, whereas drive-ins allow cars to park next to each other, the food is generally brought to the window by a server, called a carhop, and the customer can remain in the parked car to eat. However, during peak periods, to keep the queue down and avoid traffic-flow problems, drive-throughs occasionally switch to an "order at the window, then park in a designated space" model where the customer will receive their food from an attendant when it is ready to be served. This results in a perceived relationship between the two service models.

Drive-throughs have generally replaced drive-ins in popular culture, and are now found in the vast majority of modern American fast-food chains. Sometimes, a store with a drive-through is referred to as a "drive-through," or the term is attached to the service, such as, "drive-through restaurant," or "drive-through bank."

Drive-throughs typically have signs over the drive-through lanes to show customers which lanes are open for business. The types of signage used is usually illuminated so the "open" message can be changed to a "closed" message when the lane is not available.

A drive-through restaurant generally consists of:

Drive-through designs are different from restaurant to restaurant; however, most drive-throughs can accommodate four to six passenger cars or trucks at once (called the queue). Most drive-through lanes are designed so the service windows and speaker are on the driver's side of the car, for example, in left-hand traffic (right-hand drive) countries such as the UK, Ireland, Australia and New Zealand, the windows will be on the right side of the drive-through lane, and vice versa in right-hand traffic (left-hand drive) countries such as North America and mainland Europe. There are a few drive-through lanes designed with the service windows on the passenger side, but these lanes are disfavored as they cannot be used easily by cars with only a driver.
