Anyone who wants to obtain a driver’s license should know where the safety devices are and how to use them. These devices include:

1. Windshield wiper controls
2. Horn
3. Lights and dimmer controls
4. Turn signal controls
5. Ignition switch
6. Defroster button
7. Sun visors

In the test, the examiner will test the applicant on these devices to ensure that the new driver knows how to use them. Even though most examiners consider an inability to find and operate these controls to be a minor error, it might be a
sign that the learner is also missing knowledge in other areas.
