When lanes are closed for construction, paving, or painting on interstate highways in New Jersey, typically a lower speed limit is posted for the "work zone" -- for instance, 50 miles an hour in a span that is usually 65.

But what about roadside work being done on a smaller state highway, or a 35 mph residential road? How much should drivers slow down as they pass through those areas?

"Reducing a speed in a work zone is a regulatory action, and it's reserved for long-term projects that include changes to roadway configuration, lane shifts, or lane closures," Joe Bertoni, New Jersey Department of Transportation deputy commissioner, said.

And that action is governed not by New Jersey, but by the Federal Manual on Uniform Traffic Control Devices, according to information provided to New Jersey 101.5 by NJDOT.

In general, the MUTCD limits work zone speed limits to 10 miles an hour slower than usually posted, or 15 in certain cases, but only for projects taking up a mile or more.

That doesn't cover a singular utility worker up in a bucket, working on a power line, or landscapers trimming back tree branches.

So, Bertoni said, the best thing to do is be aware.

"Anytime you approach a work zone, whether it be a large or small work zone, you should proceed with caution and obey all posted construction signage," he said.

Driving through construction at the normal speed limit is never advisable, according to NJDOT, but taking it 10, 15, or 20 miles per hour slower is up to a motorist's discretion if a specific, temporary limit is not visible.

"It really, really comes down to using common sense, paying attention to your surroundings, paying attention to the activities that are occurring on the roadway," Bertoni said.

As far as personal injury or property damage caused by a driver disregarding the caution signaled by orange cones, penalties for such incidents are determined and doled out by law enforcement.

Bertoni said the overriding rule that applies in these situations corresponds to a well-known New Jersey driving law: Slow down and move over.

"We would like to bring to the attention of motorists to slow down through work zones and move over for first responders," he said. "Working together, we can make our highways safer for all."

Every NJ city and town's municipal tax bill, ranked

A little less than 30 cents of every $1 in property taxes charged in New Jersey support municipal services provided by cities, towns, townships, boroughs and villages. Statewide, the average municipal-only tax bill in 2021 was $2,725, but that varied widely from more than $13,000 in Tavistock to nothing in three townships. In addition to $9.22 billion in municipal purpose taxes, special taxing districts that in some places provide municipal services such as fire protection, garbage collection or economic development levied $323.8 million in 2021.
