If your vehicle's turn signals fail, use _________ until you can have them repaired.

Your vehicle's turn signals enable you to communicate with other drivers. It is important to ensure that they operate correctly at all times. Any change in the dashboard light indicator reflects improper operation. If the turn signals fail, use hand and arm signals until you can have them repaired. Conversely, Nebraska law requires you to use your vehicle's turn signals whenever your hand and arm signals aren't visible for at least 100 feet. [NE Code § 60-6,162]
