How UM/UIM Coverage Helped Recover $310,000 After a Semi-Truck Sideswipe Accident

Our client recovered a $310,000 settlement after a serious auto accident involving an unsafe lane change by a semi-truck driver. The collision happened while our client was traveling west on Craig Road toward the I-15 on-ramp, where the commercial vehicle sideswiped his car during a lane change. Police responded to the scene and confirmed that the other driver had no insurance, which made the case especially important because our client had UIM coverage in place at the time of impact.

What Happened

Our client reported that a semi driver operating a vehicle connected to a trucking company made an unsafe lane change into his lane and struck the side of his vehicle. Side-swipe collisions like this often happen when a driver fails to check blind spots, misjudges space, or merges too quickly in highway traffic. When a commercial vehicle is involved, the force of impact and the size of the truck can make even a seemingly brief lane-change mistake cause serious harm.

Why This Case Was Important

This case shows why uninsured and underinsured motorist (UM/UIM) coverage can matter so much after a crash. Even when the at-fault driver has no insurance, injured people may still have a path to recovery through their own UIM coverage. In a situation like this, early notice of coverage, a clear police report, and detailed accident facts can make a major difference in the strength of the claim.

Unsafe Lane Change Cases

Unsafe lane change crashes are common on busy roads, especially near highway ramps, merge lanes, and heavy commuter traffic. These cases often depend on proving which vehicle had the right of way, where the impact occurred, and whether the other driver failed to yield or check blind spots. When the other vehicle is a commercial truck, investigators also look closely at driver conduct, company responsibility, and whether federal or state safety rules may have been violated.

Understanding UM/UIM Coverage in This Case and Why it Matters

One of the most important facts in this case is that the at-fault driver allegedly had no insurance, while our client had UM/UIM coverage available under his own auto policy. UM coverage may help when the at-fault driver has no insurance, while UIM coverage may help when the at-fault driver has some insurance but not enough to fully cover the losses from the crash.

In simple terms, UM/UIM coverage acts as a safeguard when the usual source of recovery (the at-fault driver’s insurance) is missing or inadequate. That matters in real-world injury cases because a crash can cause medical expenses, lost income, pain and suffering, and other damages that quickly exceed what an uninsured or minimally insured driver can pay.

In Nevada, state law requires insurance companies to offer UM/UIM coverage when they sell motor vehicle insurance, and that offer is tied to the bodily injury liability limits sold under the policy, which is one reason this coverage deserves close attention when people choose their insurance options.

Arizona law follows a similar structure. Under Arizona Revised Statutes § 20-259.01, insurers must offer underinsured motorist coverage “in limits not less than the liability limits for bodily injury or death contained within the policy,” which means the amount of UM/UIM coverage offered should match the bodily injury liability limits a driver selects.

For drivers in both states, this coverage can make a major difference after a serious accident. Medical bills, lost wages, and other damages can add up quickly, and UM/UIM coverage may provide another source of recovery when the at-fault driver cannot fully pay. That is especially important in crashes involving unsafe lane changes, sideswipes, and commercial vehicles, where injuries can be significant.

In practical terms, UM/UIM coverage is a safeguard. It does not prevent a crash, but it can help protect injured people when the driver who caused the wreck is uninsured or underinsured. In cases like this one, that protection can be critical because it helps create a path toward recovery even when the other side cannot provide enough insurance.

That is why many drivers in Nevada and Arizona choose to carry UM/UIM coverage. It can be one of the most valuable parts of an auto policy because it adds financial protection when another driver’s insurance falls short or does not exist at all.

Why Drivers Benefit From UM/UIM Coverage

The main benefit of UM/UIM coverage is straightforward: it can create a path to financial recovery when the at-fault driver cannot. If an injured person is hit by an uninsured motorist, or by a driver whose policy limits are too low for the seriousness of the injuries, UM/UIM coverage may help address losses that would otherwise go unpaid.

This protection can be especially valuable in serious crashes involving commercial vehicles, highway collisions, or cases with significant medical treatment. Even where liability appears clear, a strong case is not enough by itself if there is no meaningful insurance available on the other side, which is exactly why UM/UIM coverage can be one of the most practical protections in an auto policy.

Another benefit is clarity. When a policy includes UM/UIM coverage, there is at least a defined insurance mechanism that may respond to the claim, instead of leaving the injured person to chase recovery from an uninsured individual with limited resources.

The Low Cost of UM/UIM Coverage

Despite the strong protection it offers, UM/UIM coverage is often one of the most affordable options on an auto insurance policy. In many cases, adding UM/UIM coverage costs only a small additional premium compared to the base liability policy, especially when compared to the potential financial exposure after a serious crash. For a relatively modest increase in monthly or annual premium, drivers can gain meaningful protection against uninsured and underinsured motorists, which can be critical when the other driver has little or no ability to pay for the harm they caused. That low-cost relative to the benefit makes UM/UIM coverage one of the most cost-effective protections available in auto insurance, particularly in states where a significant percentage of drivers remain uninsured or carry only minimum liability limits.

Why UM/UIM Coverage Mattered Here

Because the at-fault driver had no insurance, UM/UIM coverage became a critical part of this case. This type of coverage is designed to help protect injured drivers when the other party cannot fully pay for the harm they caused, whether because they have no insurance or too little insurance. In situations like this, UM/UIM coverage can make the difference between limited recovery and meaningful compensation for medical bills, lost wages, and other damages. Without that coverage, many crash victims would be left to absorb medical bills, lost income, and other damages on their own. Carrying UIM coverage can be one of the most important financial protections a driver has after a serious collision.

1. What is an unsafe lane change accident?

An unsafe lane change accident happens when a driver merges or shifts lanes without ensuring the movement is clear and safe. These crashes frequently involve sideswipes, rear-end impacts, or multi-vehicle chain reactions.

2. What if the at-fault driver has no insurance?

If the at-fault driver is uninsured, the injured person may be able to make a claim through their own uninsured motorist or underinsured motorist coverage, depending on the policy. Police reports and witness statements can help document what happened.

3. Can a semi-truck cause a sideswipe crash?

Yes. Large trucks have wide blind spots and require more space to merge safely, so an improper lane change can easily cause a sideswipe collision. These cases often involve serious injuries because of the size and weight of the commercial vehicle.

4. Why is UM/UIM coverage important after a car accident?

UM/UIM coverage can help pay for damages when the other driver cannot fully cover the loss. It is especially valuable in hit-and-run cases, uninsured driver claims, and serious crashes involving commercial vehicles.

Our client’s case is a clear example of how an unsafe lane change by a commercial vehicle can lead to a serious accident and a substantial recovery. With police confirming that the other driver had no insurance and UIM coverage available, the case had the key facts needed to support a strong settlement outcome. A $310,000 recovery in this type of crash underscores the importance of documenting the collision carefully and carrying uninsured or underinsured motorist coverage.
