A big rig driver died and a passenger was injured Wednesday morning after their semi-truck left Interstate 80 near the Donner Pass Road off-ramp in Truckee, California Highway Patrol says. The truck went off the right shoulder, went through a roadside fence, and came to rest in a ditch near a wilderness area close to the Truckee River. The driver was found unconscious in the cab, while the passenger reported feeling light-headed and was taken to a hospital by Truckee Fire personnel. CHP, CalFire, Truckee Fire, Truckee Police, and other agencies responded to the scene, and the No. 2 lane was closed for recovery operations.

ABC10 reported the crash citing the California Highway Patrol, which logged the incident as a fatal solo-vehicle collision on westbound I-80 at the Donner Pass Road off-ramp in Truckee at approximately 9:28 a.m. CHP dispatch records reviewed independently confirm that the driver was unresponsive at the scene while a passenger in the cab was transported to a hospital after reporting light-headedness. The agency’s public incident log lists the case as a “1144-Fatality” call, and lane closures remained in effect for vehicle recovery hours after the crash. Names of those involved had not been released as of Wednesday afternoon.

What the Law Says

California Vehicle Code 22406 caps the speed of big rigs, truck tractors with trailers, and other heavy vehicles at 55 mph, recognizing that their size and stopping distance make high speed especially dangerous on mountain highways like I-80 through Donner Pass. When a big rig leaves the roadway on a descent, investigators often examine whether the truck was traveling too fast for the grade and road conditions. A violation of this speed cap can support a finding of negligence in a subsequent civil claim.

Vehicle Code 21710 makes it illegal for any driver, including commercial truck operators, to coast downhill with the transmission in neutral, because doing so limits engine braking and increases the risk of brake overheating or failure on long descents. Donner Pass and the surrounding Sierra grades are notorious for runaway-truck incidents tied to exactly this kind of unsafe descent technique. If evidence shows the driver coasted or otherwise mishandled the truck’s brakes on the grade, it could be a key factor in determining fault for the crash.
