New Berlin, WI (August 27, 2025) – A two-vehicle T-bone collision at a busy New Berlin intersection led to injuries Tuesday afternoon and momentarily left one vehicle on its side. The crash occurred around 3:52 p.m. at the junction of National Ave (Hwy ES) and Lawnsdale Rd (Hwy I), prompting an urgent response from Waukesha County emergency units.
Witnesses described the force of the crash as significant, with one of the vehicles briefly tipping onto its side before returning upright. Paramedics and fire crews arrived on the scene to treat those injured. While the total number of injured individuals has not been publicly confirmed, emergency responders did administer care on-site. The severity of the injuries remains under review.
Law enforcement quickly worked to reroute traffic and stabilize the crash area, which remained partially blocked while authorities conducted a preliminary investigation. No additional transports were confirmed as of the latest update.
Investigators are currently determining whether failure to yield, excessive speed, or visibility issues contributed to the crash. The intersection is a known traffic corridor connecting local and regional commuters, and accidents at this location have occurred in the past.
We send our well wishes to the injured parties and hope for a full recovery for all involved.
T-Bone Collisions in Wisconsin
T-bone crashes—also referred to as broadside collisions—are among the most dangerous types of accidents, particularly at intersections where traffic crosses perpendicularly. The recent incident in New Berlin, where one vehicle briefly rolled onto its side, illustrates the force often involved in side-impact collisions and the risk they pose to occupants.
Unlike head-on or rear-end collisions, side impacts leave drivers and passengers exposed to severe force with relatively little structural protection. These types of crashes frequently cause injuries such as broken ribs, pelvic fractures, spinal trauma, or internal bleeding—especially when the impact occurs at higher speeds or directly at the driver’s or passenger’s door.
The intersection of National Ave and Lawnsdale Rd is a significant connector in the New Berlin area, with traffic flowing in all directions throughout the day. With increased development and ongoing commuter use, the risk of high-impact crashes remains a concern—particularly during peak afternoon hours when the recent incident occurred.
For crash victims, immediate medical attention is essential even if symptoms are delayed. Side-impact trauma may present hours or days after the crash, and early diagnosis can be critical to recovery. Navigating the aftermath—whether involving treatment, vehicle damage, or insurance questions—can be stressful without the right support.
