State officials warned New Jersey drivers to stay off the roadways as much as possible during Monday’s snowstorm to keep everyone safe.

Gov. Phil Murphy said that around 2,100 snowplows, salt spreaders and other equipment were deployed around the state to remove snow from the roads. He says that this is the most amount of equipment out on the roads in his time in office.

Murphy spoke Monday at a news conference at a state police facility in Ewing. He said that the worst of the storm would be hitting during the evening commute home.

State police reported over 400 accidents and over 300 calls for assistance by Monday evening on the state roadways.

There were also bans on commercial vehicles on stretches of Interstate 287, Interstate 280, Interstate 80 and Interstate 78. That restriction was lifted by Monday evening.

A jackknifed tractor-trailer on I-287 in Kinnelon slowed traffic southbound Monday morning. Murphy said that this is the reason for those restrictions and that he was frustrated that some truck drivers ignored the warning.

“This is where we know historically there have been issues. And it's done in cooperation and coordination with our neighbors, including, in this case most importantly, Pennsylvania and New York,” Murphy said. “So, it's quite frustrating and maddening - apparently the penalties aren't sufficient.”

The governor said that his office is considering upping the penalties for violating the commercial vehicle restriction.

Officials said that it was important for drivers to stay off the roadways as much as possible so that crews can clear the snow and ice.
