# Truck driver gets 4 years, 8 months for the fatal I-10 crash in Ontario

A big-rig driver who plowed into stopped traffic on the 10 Freeway in Ontario last fall, setting off an eight-vehicle pileup that killed three people, was sentenced to four years and eight months in prison after pleading guilty to vehicular manslaughter.

A truck driver whose speeding big rig triggered a deadly chain-reaction crash on Interstate 10 in Ontario last October was sentenced this week to four years and eight months in state prison.

## The crash

Jashanpreet Singh [pleaded guilty to three felony counts of vehicular manslaughter with gross negligence](https://www.cbsnews.com/losangeles/news/semi-truck-driver-sentenced-4-years-ontario-10-freeway-crash/) for the October 2025 collision. According to the California Highway Patrol, Singh drove his semi-truck at a high rate of speed into stopped traffic on the 10 Freeway and failed to brake in time, setting off a violent [eight-vehicle pileup that killed three people and injured four others](https://abc7.com/post/deadly-10-freeway-crash-semitruck-driver-gets-prison-ontario-killed-3/19509171/). Eyewitness accounts and dashcam footage documented the speed of the impact.

Singh was arrested at the scene on suspicion of driving under the influence, but [toxicology tests came back negative for drugs and alcohol](https://www.cbsnews.com/losangeles/news/semi-truck-driver-sentenced-4-years-ontario-10-freeway-crash/), and he was not convicted of impaired driving. The case instead turned on gross negligence behind the wheel.

## The sentence

At sentencing this week, the judge weighed factors that cut in Singh's favor: he was young enough to qualify for youthful-offender consideration under California law, had no prior criminal record, and the crash was not believed to be intentional. Those considerations shaped a term, four years and eight months, that some coverage rounded to "nearly five years." Prosecutors had described the crash as a preventable tragedy, one that took three lives because a driver did not slow for traffic ahead.

## Why it matters

Fatal crashes involving big rigs on Southern California's crowded freeways are a persistent public-safety concern, and cases like this one test how the courts balance accountability against mitigating factors when a driver's negligence, rather than intent or intoxication, causes multiple deaths. For the families of the three people killed, the sentence closes one chapter of a case that began with a routine afternoon of traffic on one of the region's busiest freeways. The names of all three victims had not been fully released by authorities.
