Uninsured &
Underinsured Motorist.
Liability covers the damage you cause. But what happens when the other driver is at fault and carries no insurance — or the NJ state minimum that runs out in an afternoon? UM/UIM is the coverage that protects your driver when someone else’s lack of insurance becomes your problem.
Two scenarios, one coverage
Uninsured/Underinsured Motorist coverage steps in when the other driver is at fault but can’t pay for the injuries they caused to your driver and occupants:
- Uninsured Motorist (UM) — the at-fault driver has no insurance at all, or flees the scene (hit-and-run). Your UM coverage pays as if it were their liability policy.
- Underinsured Motorist (UIM) — the at-fault driver has insurance, but their limits are too low to cover the harm. UIM pays the difference up to your UIM limit.
The New Jersey reality
Two facts make UM/UIM essential for NJ commercial vehicles. First, a real share of drivers on NJ roads carry no insurance despite the requirement. Second — and bigger — a huge number carry only the state minimum of 35/70/25 — better than the 15/30/5 New Jersey sat on for decades, and still thin. A serious injury to one of your drivers easily exceeds $30,000, and when the at-fault driver’s policy taps out, the rest of the bill has nowhere to go but your UIM coverage.
Match your liability limit
The single best practice with UM/UIM is to set it equal to your liability limit. If you carry $1M liability, carry $1M UM/UIM. It would be strange to protect strangers from your driver at $1M while protecting your own driver from strangers at only $15K — yet under-set UM/UIM is one of the most common gaps we find on policies written elsewhere.
In New Jersey, carriers are required to offer UM/UIM, and there are rules about how limits relate to your liability selection. We’ll walk you through the options and, in almost every case, recommend matching limits.
Inexpensive for the protection
UM/UIM is generally a small fraction of your total premium — raising it to match a $1M liability limit typically adds far less than the liability itself costs. Like a commercial umbrella, it’s one of the most cost-effective protections per dollar on the policy, precisely because the catastrophic claims it guards against are infrequent but devastating.
Build the complete stack.
UM/UIM is the mirror image of liability. Most NJ commercial policies carry both, ideally at matching limits.
