HONOLULU (KHNL) - Right about 12:45 p.m. Friday, a dump truck swerved from the H-1's middle lane and hit the concrete median dividing the highway. The impact caused the truck to tip over, blocking eastbound lanes near Kapahulu.
The driver told investigators he was trying to avoid hitting another car.
"He reported that this vehicle was swerving in front of him, cutting him off," said Lt. Gerrit Kurihara of the Honolulu Police Department.
"The driver reported he swerved to avoid collision, a possible collision," Kurihara said.
Police said after the truck turned over the driver became agitated and started walking out into lanes of traffic. Investigators said he was arrested for disorderly conduct and taken to the Queens Medical Center for treatment.
The truck spilled diesel fuel across the roadway. Diesel requires higher temperatures than gasoline to catch fire but fire crews still worried about the possibility of an explosion.
"If you had a choice between gasoline and a diesel spill, normally you would want it to be diesel, but in any case it's not a good thing," said Capt. Kenison Tejada of the Honolulu Fire Department.
Police said the accident could easily have been much worse.
