A new bill proposed will allow drivers to open up an app on their cell phone to show an officer the auto insurance card. The bill will allow electronic insurance cards to be used, but not mandated. This means that you can still carry the paper card.
The bill was approved by the assembly in January 2015. When implemented, it will bring New Jersey in line with about 37 other states that allow drivers to display proof of insurance on their smart phone.
Now the down side. Typically, when the officer asks you for your insurance card, they take it back to their police car to do what they need to do. Does this mean that you will give them your phone to take to their car to do whatever they wish? Very risky if you ask me. While I embrace technology, I will keep a paper copy for the officer!
