A steering wheel lock, also known as a steering wheel club or steering wheel lock bar, is a security device that is designed to prevent unauthorized use of a vehicle. When a steering wheel is locked, it becomes difficult or impossible to turn, making it difficult for the vehicle to be driven. Many newer vehicles are equipped with steering wheel locks that automatically engage when the vehicle is parked and the ignition is turned off.

There are a few different reasons why a steering wheel lock might engage when a vehicle is parked. One reason is to prevent theft. By making it difficult or impossible to steer the vehicle, a steering wheel lock can discourage potential thieves from attempting to steal the car.

Another reason for a steering wheel lock is to prevent the vehicle from rolling away. If a car is parked on an incline, the weight of the vehicle can cause it to roll downhill unless the wheels are locked. A steering wheel lock can help to keep the vehicle in place and prevent it from rolling away.

A third reason for a steering wheel lock is to prevent unauthorized use of the vehicle. If a car is parked in a public place, someone other than the owner might attempt to drive it away. A steering wheel lock can help to prevent this from happening by making it difficult or impossible for the car to be driven.

There are a few different ways that a steering wheel lock can be engaged. Some steering wheel locks are manual, meaning that the driver must manually lock the steering wheel when the vehicle is parked. Other steering wheel locks are automatic, meaning that they engage automatically when the ignition is turned off and the car is parked.

In conclusion, a steering wheel lock is a security device that is designed to prevent unauthorized use of a vehicle. It can be used to discourage theft, prevent the vehicle from rolling away, and prevent unauthorized use of the car. Steering wheel locks can be manual or automatic, and can be engaged in a variety of ways depending on the specific device.
