Final answer:
The top of the steering wheel should be no higher than the driver's shoulder for safety and ergonomic reasons. This position helps maintain vehicle control and ensures airbag effectiveness while preventing fatigue and discomfort.
Step-by-step explanation:
The height of the top of the steering wheel in relation to the driver should be adjusted for safety and comfort. It is recommended that the top of the steering wheel be no higher than the driver's shoulder. This positioning helps ensure that the driver can maintain control of the vehicle without having to reach too far, which could impede their ability to steer quickly in an emergency. Moreover, having the top of the steering wheel aligned with the shoulders ensures that the airbag, if deployed, will provide the intended protection without causing additional injury.
Proper steering wheel height is crucial for ergonomics and to prevent fatigue during long drives. If the steering wheel is too high, it can cause the driver to raise their arms in an unnatural position, leading to discomfort or even injury over time. Conversely, if the wheel is too low, it might interfere with leg movement or cause the driver to slouch. Adjusting the steering wheel so that its top is level with the shoulders, and ensuring that there is a slight bend in the elbows when holding the wheel, can provide a safe and comfortable driving position. Drivers should also keep in mind other adjustments such as seat height and distance from the pedals for a complete ergonomic setup.
