Massive Tanker Blast Stuns California

A fuel tanker carrying 8,600 gallons of gasoline exploded on Highway 99 in Selma, and the fire shut down the road for hours.

Quick Take

The crash happened on southbound Highway 99 near Second Street in Selma.
News reports say a fuel tanker hit a box truck and burst into flames.
Both drivers escaped with minor injuries, according to the California Highway Patrol (CHP).
The public record still shows a split on the crash cause, with early reports differing from later CHP-based accounts.

How the Fire Started

Multiple local reports agree that the fire began after a collision on southbound Highway 99 in Selma near Second Street. The tanker was carrying about 8,600 gallons of fuel, and the blaze quickly grew into a major roadside emergency. Southbound lanes closed for hours, and traffic was pushed onto other roads while crews fought the flames and cleared the scene.

CHP-based reporting says the box truck was disabled on the shoulder before the tanker struck it. One account says the box truck had a flat tire and had been waiting about 10 minutes for help. That version also says the tanker drifted into the shoulder and hit the truck, which then ignited. The scene was dramatic, but the basic chain of events is still the center of the story.

What Officials and Reports Say

The injury picture is much less severe than the fireball suggested. The Fresno Bee reported that both drivers had minor injuries, and ABC 7 said both drivers got out safely, with one person treated for minor burns. Other local coverage said the tanker was fully engulfed, while the box truck took major damage. The crash forced a full closure of the southbound lanes, with detours sent through nearby streets and alternate highways.

That mix of speed, fuel, and traffic made this a large public safety problem, even though the injuries were limited. Firefighters had to deal with a burning fuel load on a busy highway, which can endanger nearby drivers, responders, and homes. The closure also shows how one crash can ripple across a whole region, especially on a major freight route like Highway 99.

Why the Cause Is Still Unclear

The reporting does not tell one clean story about fault. One syndicated account said officials believed an unsafe lane change caused the crash. Later reports based on CHP comments described a disabled box truck on the shoulder that was struck by the tanker. Those are not the same account, and the available reporting does not include the full collision file needed to settle the issue.

That gap matters because early crash reports often lock in a theory before the public sees the records. Here, the fireball is easy to see, but the key questions are harder: where each vehicle sat, whether the box truck was fully on the shoulder, and what the tanker did in the seconds before impact. Without the CHP report, the public has strong facts about the fire, but weaker proof on the cause.
