Gov. Mikie Sherrill announced several restrictions on commercial vehicle travel and suspension of NJ Transit bus and light rail services on Sunday during a news conference on Saturday.

"We are expecting a storm, the likes of which we haven't seen in years. It is going to present very dangerous conditions for travel," she said.

NJ Transit bus, light rail and AccessLink services will be suspended statewide effective Sunday at about 4 a.m. The commuter rail system will operate until 2 p.m. Sunday.

"We gave the governor our recommendations, and it was based on the prudent judgement that it's better to secure the service and temporarily suspend it, and we can resume it as soon as the snow is over, and the conditions allow," said NJ Transit President and CEO Kris Kolluri.

Drivers who are not planning on using public service are also expected face challenges on the road Sunday.

"If you do not have to be on the roads, please, we urge you, stay home," said New Jersey State Police Acting Superintendent David Sierotowicz. "If you do have to be on the roadway, and you see an emergency vehicle, please, slow down and move over. Allow them room to perform their duties."

Commercial travel on the state’s highways will be restricted to personnel carrying medical supplies, food and fuel. Utility vehicles and public safety workers will also be exempt.

"The roads are very cold. There will be accumulation. There will be ice on the ground. We're not expecting the temperatures to go above freezing," Sherrill said. "So, we're really going to have some dangerous conditions."

The New Jersey Department of Transportation will reduce the speed limit to 35 mph on the New Jersey Turnpike, Garden State Parkway, Atlantic City Expressway, and all state highways.

While there is no exact time on when full transit service will resume, Sherrill said her office will be issuing regular updates.
