Key Takeaways
Two Notch Road is one of Columbia's most accident-prone truck corridors, with local business owners describing it as "accident-prone just because of how the infrastructure is set up." Dangerous segments include I-20 East to Parklane Rd and Atrium Way to Greengage Park Rd. A firetruck struck and killed Carolyn Collins, 64, at Two Notch & Decker Blvd in July 2025, illustrating the lethal risk of heavy-vehicle collisions at these intersections. Richland County recorded 12,731 collisions and 65 fatal crashes in 2023. South Carolina gives victims 3 years to file (S.C. Code § 15-3-530) with recovery if less than 51% at fault.
Two Notch Road: Columbia’s Accident-Prone Truck Corridor
Two Notch Road is one of northeast Columbia’s busiest commercial corridors — and one of its most dangerous for truck accidents. Local business owners describe it as “accident-prone just because of how the infrastructure is set up.” The road’s design, with multiple dangerous segments, heavy commercial truck traffic from retail and distribution operations, and high-speed through traffic, creates a sustained pattern of severe collisions.
Richland County recorded 12,731 total collisions and 65 fatal crashes in 2023. Two Notch Road’s combination of aging infrastructure, dense commercial development, and truck traffic from the I-20 corridor accounts for a disproportionate share of those crashes in the northeast Columbia market.
Dangerous Segments on Two Notch Road
I-20 East to Parklane Road
This segment begins where trucks exit I-20 at highway speed and immediately enter the Two Notch Road commercial zone. The transition from interstate to surface road happens abruptly, with trucks decelerating from 65+ mph into a corridor with traffic lights, turn lanes, and cross-traffic within a quarter mile. Rear-end collisions are common as trucks cannot stop in time for red lights or backed-up traffic at Parklane Road. During morning rush, westbound commuter traffic queues at the I-20 on-ramp while eastbound trucks attempt to merge in — creating dangerous cross-traffic conflicts.
Atrium Way to Greengage Park Road
This stretch is lined with shopping centers, medical offices, and restaurants that generate constant turning-movement conflicts. Delivery trucks servicing retail businesses block travel lanes and sight lines. The multiple driveways and median cuts along this segment create dozens of potential conflict points where trucks making left turns across traffic must judge gaps in fast-moving through traffic. Failed gap judgments result in T-bone collisions with devastating consequences.
Two Notch Road & Decker Boulevard
The intersection of Two Notch Road and Decker Boulevard was the site of a fatal crash in July 2025 when a firetruck struck a sedan making a left turn, killing Carolyn Collins, 64. While the striking vehicle was an emergency vehicle rather than a commercial truck, this crash illustrates the fundamental danger of the intersection: large, heavy vehicles colliding with passenger cars making left turns. Commercial trucks face the same physics. A loaded tractor-trailer striking a turning sedan at this intersection would produce catastrophic or fatal injuries.
Why Two Notch Road Is Dangerous for Truck Accidents
Infrastructure Design Flaws
Two Notch Road’s infrastructure was designed for an earlier era of lighter traffic. The road has been repeatedly widened and modified without comprehensive redesign, resulting in inconsistent lane widths, awkward merge points, and intersection geometry that does not accommodate modern truck sizes. Signal timing does not account for the longer clearance time trucks need to complete turns. The result, as local business owners describe, is a road that is structurally predisposed to crashes.
Commercial Truck Traffic Volume
Two Notch Road serves as a primary delivery route for the dense retail and commercial corridor stretching from I-20 to the northeast suburbs. Box trucks, delivery vans, tractor-trailers, and fuel tankers service dozens of businesses along the corridor daily. These trucks share lanes with commuters, school buses, and pedestrians — a volatile mix that the road’s design cannot safely accommodate. Distribution operations connected to the I-20 corridor add through-truck traffic that has no destination on Two Notch Road but uses it as a shortcut.
Speed and Signal Issues
Posted speeds of 40-45 mph are routinely exceeded. Long signal cycles at major intersections encourage red-light running as drivers — including truck drivers — attempt to avoid extended waits. An 80,000-pound truck running a red light at 45 mph generates collision forces that no passenger vehicle can withstand. The long gaps between signals also encourage high-speed travel, with trucks reaching speeds that make emergency stopping impossible when conditions change.
Common Truck Crash Types on Two Notch Road
Left-Turn Collisions
The most dangerous and frequent crash pattern on Two Notch Road. Trucks or passenger vehicles making left turns across traffic misjudge the speed or distance of approaching vehicles. The Carolyn Collins fatality at Decker Boulevard exemplifies this pattern. When a loaded truck is the through vehicle striking a turning car, the size and weight differential makes survival unlikely for the car’s occupants.
Rear-End Collisions
Traffic backing up at intersections and driveways creates stop-and-go conditions that trucks cannot navigate safely. A truck following too closely — or a distracted truck driver checking a GPS or delivery manifest — strikes the vehicle ahead at full corridor speed. Chain-reaction crashes involving multiple vehicles are common when a truck rear-ends a car into the vehicle ahead.
Sideswipe and Lane-Change Crashes
Trucks changing lanes to access turn lanes or avoid stopped traffic sideswipe adjacent vehicles. Two Notch Road’s inconsistent lane widths mean trucks already occupy most of their lane, leaving minimal margin for error. Passenger vehicles in a truck’s blind spot are struck without warning when the truck initiates a lane change.
Liable Parties
| Potentially Liable Party | Basis for Liability |
|---|---|
| Truck driver | Speeding, red-light running, distracted driving, failure to yield on left turns, following too closely |
| Trucking company | Negligent hiring, HOS violations, failure to train drivers for urban corridor navigation |
| Retail/commercial businesses | Directing delivery trucks to use unsafe access points, failing to provide off-street loading areas |
| Government entity (SCDOT/Richland County) | Infrastructure design defects, inadequate signal timing, failure to redesign known dangerous segments (subject to SC Tort Claims Act, S.C. Code § 15-78-80) |
| Vehicle manufacturer | Brake system defects, inadequate mirrors or blind-spot detection systems |
What to Do After a Truck Accident on Two Notch Road
- Call 911 immediately — Two Notch Road falls under Richland County Sheriff or Columbia Police jurisdiction depending on the exact location.
- Do not move your vehicle unless directed — Left-turn and intersection crash evidence is critical for reconstruction.
- Document the truck: Company name, USDOT number, trailer number, cargo type, and whether the truck was making a delivery or traveling through.
- Check for cameras: The dense commercial corridor means numerous business surveillance cameras may have captured the crash. Note their locations.
- Get medical treatment: Prisma Health Richland is the closest Level I trauma center. Left-turn and T-bone collisions frequently cause delayed-onset injuries.
- Contact a truck accident attorney — ELD data, delivery logs, and the truck’s event data recorder must be preserved immediately.
South Carolina Law
- Statute of limitations: 3 years from the date of injury (S.C. Code § 15-3-530)
- Comparative fault: South Carolina allows recovery if you are less than 51% at fault. Your compensation is reduced by your percentage of fault.
- Infrastructure liability: If road design defects contributed to the crash, claims against SCDOT or Richland County are subject to the SC Tort Claims Act with notice requirements and damage caps
- Punitive damages: Available when trucking companies or drivers demonstrated willful disregard for safety, such as falsifying logs or ignoring known vehicle defects
