Frequently Asked Questions
Is the company liable for their driver's actions?
Generally yes, if the driver was acting within the scope of employment. This is called vicarious liability and typically provides access to the company's commercial insurance.
What are driver logs and why do they matter?
Commercial drivers must keep logs of their driving hours. Violations of hours-of-service rules can indicate driver fatigue and company negligence.
How do I preserve electronic evidence?
Send a formal preservation letter immediately. Many commercial vehicles have GPS, cameras, and telematics that can be overwritten if not preserved.
What if the company destroys evidence?
Destroying evidence after notice of a claim can result in legal penalties and adverse jury instructions. Document your preservation request.
Why is commercial insurance different?
Commercial policies typically have higher limits than personal auto insurance, potentially providing more compensation for serious injuries.
Time-sensitive evidence may be at risk.
