‘Toxic’ Tesla Fire Shuts Down California’s I-80, Continuing Concerns About EV Safety

By: Sam Watanuki | Published: Aug 20, 2024

In the early hours of August 19, 2024, a Tesla electric big rig veered off Interstate 80 near Emigrant Gap in the Sierra Nevada, igniting a massive fire.

The flames, fueled by the truck’s batteries, burned fiercely for hours, forcing the closure of both directions of the highway. First responders faced a unique and dangerous challenge, unlike traditional vehicle fires.

A Hazardous Materials Situation

The fire quickly escalated into a hazardous materials situation due to the toxic fumes released by the burning batteries. The California Highway Patrol (CHP) and Cal Fire teams were on high alert as they worked to contain the fire and protect nearby residents.

Authorities established a half-mile exclusion zone, keeping people at a safe distance from the potentially deadly fumes.

The Challenge of Extinguishing EV Fires

Electric vehicle fires, like the one involving the Tesla semi, pose significant challenges for firefighters. Traditional methods of using water are often ineffective, requiring tons of gallons or specialized dry chemicals to control the blaze.

Despite their best efforts, the fire continued to burn more than four hours after it started, highlighting the difficulties of managing EV-related incidents.

I-80 Shutdown: A Major Disruption

The fire forced the closure of Interstate 80, one of California’s key transportation routes, during the busy morning hours. Westbound lanes were closed at Highway 20, and eastbound lanes were blocked at Nyack, causing significant traffic disruptions.

CHP rerouted semis and other vehicles, leading to delays and frustrations for commuters and truckers alike.

A Close Call, No Injuries Reported

Despite the severity of the incident, there were no injuries reported. The big rig driver managed to escape unharmed after the vehicle veered off the roadway and into the trees.

The quick response from CHP and Cal Fire ensured that the situation was contained, preventing further damage or injury in the surrounding area.

A Growing Concern

This Tesla truck fire is not an isolated incident. Electric vehicle fires have become a growing concern for first responders and the public. In 2023, it took 6,000 gallons of water to extinguish a Tesla Model S fire on Highway 50 that “spontaneously” ignited.

Governor Newsom's Role in the Legislation

Governor Gavin Newsom has previously vetoed similar legislation, citing the existing authority of the California DMV to regulate autonomous vehicles. However, the lack of progress on draft regulations has left some lawmakers and safety advocates frustrated.
