Dar marcha atrás vs. retroceder
When talking about moving a vehicle backward, both dar marcha atrás and retroceder are used in Spanish, but they carry slightly different nuances. The phrase dar marcha atrás is highly specific to driving and focuses on the mechanical action of using the reverse gear. On the other hand, retroceder is a broader verb that focuses on the physical spatial movement of going backward, regardless of the mechanics involved.
Dar marcha atrás
The phrase dar marcha atrás translates directly to putting a vehicle in reverse gear. It is the most common and natural expression used in everyday driving situations, such as parking or maneuvering a car, to explicitly indicate that the driver is shifting the vehicle into reverse to move backward.
Tuve que dar marcha atrás para salir del aparcamiento.
(I had to reverse to get out of the parking space.)

(The truck tried to reverse in the narrow street.)

(If you miss the exit, you cannot reverse on the highway.)

(Be careful reversing because there is a child behind the car.)
Mi coche tiene un problema mecánico y no me deja dar marcha atrás.
(My car has a mechanical problem and will not let me reverse.)
Retroceder
The verb retroceder translates to backing up or moving backward. When applied to a vehicle, it focuses entirely on the directional movement (going back) rather than the act of changing gears. It is often used to describe backing away from a hazard, making space for another vehicle, or describing the movement of vehicles that do not necessarily have a traditional reverse gear, like a train.
El conductor decidió retroceder para dejar pasar a la ambulancia.
(The driver decided to back up to let the ambulance pass.)

(The train had to back up to the previous station due to a track failure.)

Retroceder en esta vía de un solo sentido es una maniobra muy peligrosa.
(Backing up on this one-way road is a very dangerous maneuver.)
Summary
In summary, choose dar marcha atrás when you want to talk about the specific driving action of putting a car in reverse, which is typical for daily driving and parking. Choose retroceder when you want to emphasize the physical direction of backing up a vehicle, usually to create space, retreat from an obstacle, or describe backward motion in a more general sense.
