FMCSA Rules and Driver Logs in Glendale Truck Cases

By Payam Soliemanzadeh, Founder and President

Key takeaways

• FMCSA hours-of-service violations on State Route 134 or Interstate 5 establish negligence per se in your claim.
• Electronic logging device data must be preserved immediately or it may disappear within days of the collision.
• Your case will be filed at Glendale Courthouse, 600 East Broadway, Glendale, CA 91206.
• CCP §335.1 gives you two years; Gov. Code §911.2 gives six months if a government agency is liable.

Commercial trucks move freight through Glendale daily on the Ventura Freeway, the Golden State Freeway, and the Glendale Freeway, as well as surface corridors like San Fernando Road and Glenoaks Boulevard. When those trucks are operated by fatigued drivers who have exceeded federal hour limits, the consequences can be catastrophic. Federal rules exist precisely to prevent driver exhaustion and the crashes it causes.

Hours-of-service regulations and mandatory electronic logs create a detailed, timestamped record of every driver's compliance—or lack thereof. Those records become powerful evidence in a truck accident lawsuit, shifting the burden to the carrier and making liability far easier to prove. Understanding how these rules work, what they require, and how violations affect your claim is essential to recovering full compensation.

Federal hours-of-service rules and what they require

The FMCSA limits property-carrying drivers to eleven hours of driving within a fourteen-hour window after ten consecutive hours off duty. Drivers must take a thirty-minute break after eight cumulative hours of driving. A driver may not drive beyond the fourteenth hour on duty, and weekly limits cap driving at sixty hours over seven days or seventy hours over eight days. These rules apply to virtually every commercial truck traveling California highways, including those passing through Glendale on Interstate 5 or State Route 134.

Violations are common. Carriers face pressure to meet delivery deadlines, and drivers face pressure to maximize mileage. When a driver exceeds hour limits, reaction time slows, judgment deteriorates, and the risk of a collision multiplies. If logs show a violation at or near the time of your crash, that violation is not just relevant—it is often dispositive on the question of negligence.

Electronic logging devices and the evidence they create

Since December 2017, federal law has required most commercial trucks to use electronic logging devices that automatically record driving time, engine hours, vehicle movement, and miles driven. ELDs sync with the truck's engine and cannot be manually altered in the way paper logs once were. The device captures location data, speed, and duty status in real time, creating a digital trail that is far harder for a driver or carrier to manipulate or destroy.

That data, however, is not preserved indefinitely. Many ELD systems overwrite records after as little as seven to fourteen days, and carriers are required to retain logs for only six months. If you wait to investigate or fail to send a preservation letter immediately after the collision, critical evidence may vanish. Early action by counsel is not optional—it is the difference between a strong claim and one that collapses for lack of proof.

How violations translate into liability and damages

Under California law, a violation of a statute or regulation designed to protect the public constitutes negligence per se, meaning the defendant's breach of duty is established as a matter of law. When a driver's logs show hours-of-service violations, you do not need to argue that fatigue was negligent—the violation itself proves it. The burden then shifts to the defendant to show the violation did not cause the crash, a difficult standard to meet when the collision occurred during the period of unlawful driving.

Violations also implicate the carrier. Federal law holds motor carriers vicariously liable for driver conduct and independently liable for failing to enforce compliance programs, inspect logs, or discipline repeat violators. If the carrier knew or should have known of chronic violations, punitive damages under Civil Code §3294 may be available. Those damages require proof of malice, oppression, or fraud, and a pattern of falsified or ignored logs can meet that threshold, especially if the carrier's records reveal deliberate indifference to safety rules.

Local details

Truck accidents in Glendale are litigated in the North Central District of the Los Angeles Superior Court at Glendale Courthouse, 600 East Broadway, Glendale, CA 91206. Your attorney will file the complaint there, and all motions, discovery disputes, and trial proceedings will take place at that location. If you are seriously injured, you will likely be transported to Huntington Hospital in Pasadena, a Level II trauma center at 100 West California Boulevard, where treatment records will document the full extent of your injuries and form a core part of your damages case.

Crashes involving hours-of-service violations occur most often on high-volume corridors. State Route 134 (Ventura Freeway), Interstate 5 (Golden State Freeway), and State Route 2 (Glendale Freeway) carry steady commercial traffic, as do Brand Boulevard, Glenoaks Boulevard, and San Fernando Road. Each of these routes presents distinct hazards—tight merge lanes, steep grades, and frequent congestion—that magnify the danger when a driver is fatigued and slower to react.

Frequently Asked Questions

How quickly must I obtain the truck's electronic logs?

Immediately. Many ELD systems overwrite data within seven to fourteen days, and carriers are required to preserve logs for only six months. Your attorney should send a spoliation letter within days of the collision to ensure all electronic records, including logs, GPS data, and maintenance files, are preserved. Delay can result in permanent loss of critical evidence.

Can I still recover if the logs were destroyed or tampered with?

Yes. California courts permit an adverse inference when a party destroys evidence it had a duty to preserve. If the carrier failed to retain logs or altered them, the jury may be instructed to presume the missing evidence would have been unfavorable to the defendant. This inference can be powerful, especially when combined with testimony about the carrier's record-keeping practices.

What if the driver was an independent contractor?

Carriers remain liable under federal law even when drivers are classified as independent contractors, provided the carrier exercises sufficient control over routes, schedules, or equipment. California's ABC test under Assembly Bill 5 further restricts independent-contractor classifications in the transportation industry. Your attorney will analyze dispatching records, lease agreements, and operational control to establish the carrier's liability regardless of the driver's formal classification.

Does a violation alone prove the truck driver caused the crash?

No, but it establishes a presumption. A hours-of-service violation proves negligence per se, meaning breach of duty is established. You must still show causation—that the violation contributed to the collision. Fatigue reduces reaction time and impairs judgment, so causation arguments are strong when the violation occurred at or near the time of the crash, particularly in rear-end or lane-departure cases.
