Silverado or Sierra: Safety Systems

Safety is paramount for both the GMC Sierra and Chevy Silverado.

Both also come standard with six airbags. What the Sierra has as standard that the Silverado doesn’t, however, are the following two systems: 

  • LED Daytime Running Lamps: These subtle but crucial lights make it easier for drivers and pedestrians to see you, even if it’s a bright and sunny day. 
  • Teen Driver Tech: Have a new driver in the family? Teen Driver technology lets you limit certain features, such as speaker volume, and provides an in-vehicle report card, so you can give constructive feedback to your teen driver.
