There are many mistakes that can lead to a truck crash, but one issue can strongly affect an injury claim. In South Carolina, truck drivers and trucking companies must follow Hours-of-Service (HOS) rules. These safety regulations prevent fatigued driving, which is a common and dangerous factor in serious commercial vehicle collisions.
What are HOS rules?
Most commercial truck drivers must follow Federal Motor Carrier Safety Administration (FMCSA) HOS limits. These limits restrict how long they can drive before going off-duty or taking required breaks. Simply put, the rules aim to keep tired drivers off the road.
When drivers exceed legal driving hours or skip rest breaks, fatigue can negatively impact their driving performance. Tiredness slows down reaction time, impairs judgment and increases the risk of crashes or collisions. HOS compliance can become a key liability issue in truck accident claims.
How they affect your claim
Hours-of-Service (HOS) violations can help prove negligence if a tired driver caused your crash. Breaking these federal rules is strong evidence the driver failed to act safely toward other drivers, including you.
In South Carolina accident cases, you can often prove HOS violations by reviewing the driver’s logbook, dispatch records and other related documents. A legal professional can request and review these records to see whether the driver drove longer than the law allows.
HOS problems can also strengthen other parts of your case. For example, if the driver or company falsified logbooks, it may count as reckless behavior. Under South Carolina law, this can support a claim for punitive damages.
Preserving critical evidence
HOS rules do not automatically “win” your case. However, when there are violations, they can be powerful proof of fatigue and unsafe company practices. If you suspect driver fatigue contributed to the crash, preserving evidence immediately is crucial.
Consider reaching out to a legal professional in South Carolina with experience in truck litigation. Due to time-sensitive evidence, HOS cases often require fast action and detailed investigation.
