2. Frontal lobe is responsible for motor skills which help eto drive the car. This also helps to make decisions like what to do if there is an accident etc.

3. Cerebellum is responsible for regulation of our emotions. If wwe are angry while driving we might be in the mood to take risks and drive rashly which will cause harm.

4. Occipital lobe is important because is helps with vision. Visuo perceptual skills helps us to drive. If there is any damage to this lobe, we will not be able to see clearly.
