Minnesota driver's manual updates text for legal gun owners

The change was announced Monday - four years after Philando Castile was fatally shot after telling an officer he had a gun.

"It's a bittersweet day. It's been four years now, and it seems like yesterday," Valerie Castile, his mother, said. 

Authorities learned after the shooting that Castile had a permit to carry the firearm legally.

Castile's mother pushed for the change. It is one of one of 28 recommendations made by a working group that on deadly encounters with police.

"This little tidbit is very, very important," Valerie Castile said. "That bit of information can save lots of lives because you don't know what you're going to get when the police walk up to your car."

The guidelines for drivers are: 

• Keep your hands on the steering wheel
• Tell the officer who pulls you over that you have a firearm and where it is
• Do not reach around in the car or get out

The update also lays out expectations for law enforcement: 

• Greet you
• Identify themselves
• Ask for your license and registration
• Tell you why they pulled you over
