Tuesday's ruling comes in the case of a couple who lost both their legs when their motorcycle was hit by a teenager who was texting and driving in Morris County in 2009.
The motorists had sued his girlfriend who sent him messages. The judges upheld a lower court ruling that dismissed the lawsuit.
The appeals court says someone who texts a motorist is not liable for the driver's negligent actions. But the texter has a duty to refrain if the person knows the recipient is driving and likely to read the message.
The injured couple settled their lawsuit against the driver for $500,000.
