My Uncle Archie told me that once I handed the cop my registration and license, to put my hands on the top of the steering wheel, and wait. If it was dark, to turn on the dome light before I put the hands on the steering wheel. It helps the cops keep from being so nervous. I wasn’t yet driving when he said that, but I’ve remembered it all these years. He was in Glendale PD at the time.
That’s what my husband said I should have done too.
