A motorcyclist was injured Monday afternoon when a multi-vehicle crash shut down lanes on southbound Interstate 15 near Cleghorn Road, snarling Labor Day traffic through the Cajon Pass for hours. The crash, reported at about 1:04 p.m., left a motorcycle down in the two middle lanes of the freeway and forced California Highway Patrol units to block the No. 4 lane while they worked the scene.
According to VVNG, the crash involved the motorcycle, a white Jeep Grand Cherokee, and a silver Toyota Camry. Per a crash participant cited in California Highway Patrol incident logs, the motorcycle struck the rear of the Jeep. The Jeep reportedly had three small children inside, though available information did not specify whether any of them were injured in the collision. The exact cause of the crash remains under investigation by authorities, and it was not immediately clear how badly the motorcyclist was hurt, though a subsequent caller referenced a medical response, per the same incident logs.
Traffic Backed Up Into the High Desert
Traffic control measures were put in place on southbound I-15 over Cleghorn Road as crews cleared the scene, and traffic was heavy as of about 2 p.m. The backup stretched along southbound I-15 from around Joshua Street, according to the outlet's report, forcing motorists traveling through the Cajon Pass into a slow crawl during one of the year's busiest travel weekends.
The timing made the delays especially painful. The crash landed squarely inside the California Highway Patrol's 78-hour Maximum Enforcement Period for Labor Day weekend, a statewide surge that ran from 6:01 p.m. Friday through 11:59 p.m. Monday, according to KHTS Radio. Every available CHP officer was deployed statewide during the enforcement window as part of a push to curb impaired driving.
A Familiar Trouble Spot in the Cajon Pass
A Familiar Trouble Spot in the Cajon Pass This is not the first serious motorcycle crash near Cleghorn Road this year. Just 31 days earlier, Hoodline reported that a male motorcyclist was killed after colliding with a guardrail in the same stretch of southbound I-15, a crash that also closed the No. 4 lane for hours and pushed traffic onto Highway 138. A separate report attributed to VVNG described an incident in which an Apple Valley motorcyclist was airlifted after slamming into a UTV trailer.
The pattern goes back further still. VVNG previously reported that Erek I. Brown was killed in a hit-and-run crash. Officers in that case later located an abandoned suspect vehicle at the Highway 138 off-ramp.
Why This Stretch of Freeway Keeps Backing Up
Why This Stretch of Freeway Keeps Backing Up The Cleghorn Road interchange sits at a natural chokepoint. Interstate 15 through the Cajon Pass carries heavy traffic over steep mountain terrain with no direct alternate route, which is why even a single blocked lane near Cleghorn Road can send backups rippling for miles toward Hesperia. Commercial trucks routinely mix with passenger vehicles and High Desert commuters in the same tight lanes.
The location also sits near a jurisdictional seam. Freeway incidents like Monday's crash can involve county sheriff and CHP patrols.
Open Questions and Rider Risk
Open Questions and Rider Risk Investigators have not said whether lane positioning, sudden braking, or a speed differential contributed to the motorcycle striking the Jeep's rear end, and the cause remains under investigation.
The stakes for riders remain steep regardless of fault. Motorcyclists can suffer severe injuries in crashes, in part because they lack any structural enclosure. State figures released by the California Office of Traffic Safety show 583 motorcyclists were killed on California roads in 2023 alone, accounting for 14 percent of all traffic deaths statewide — a total that had declined 10.2 percent from the year before. Nationally, traffic risks remain a concern, even as the dangers concentrated along steep, congested corridors like the Cajon Pass persist.
