How do state-specific intrastate HOS rules differ from federal rules?

Intrastate HOS rules are governed by state laws and often differ from federal FMCSA regulations.

• Common differences: Longer driving hours (some states allow up to 12 or more hours of driving in a day).

• States may permit extended on-duty periods, exceeding the federal 14-hour limit.

• States often have additional exemptions for certain industries, such as agriculture or forestry.

Drivers must understand both federal and state rules to ensure compliance with the appropriate regulations based on their operations.
