That got the attention of a trooper who was on the other side of the highway.

“When the Trooper reached the SUV it was unattended and showed signs of having crashed into a jersey barrier,” State Police spokesman Dave Procopio said in a statement Friday.

Moments later, Byrne walked up to the trooper and they talked. The trooper discovered Byrne had been driving the SUV and gave him a field sobriety test, which he failed, according to State Police.
