A vehicle inspection pit or grease pit is a pit or trench over which a vehicle can be driven and parked to be serviced from beneath. They are typically situated in vehicle inspection bays or garages. The use of a pit by a technician negates the need for a jack or winch. Inspection pits have to be narrow enough to fit between the wheels of a vehicle yet wide enough for a technician to work within. Access to the pit is provided by stairs or steps.[1]
Falls into pits are common accidents in vehicle inspection bays. It is advised to place a net over unoccupied vehicle inspection pits to protect against falls.[1] It is important that the pit is well ventilated to prevent fires and explosions from hazardous substances.[2]
