Does the National Park Service use a different set of laws regarding SS on speeding tickets than the state the park is in?
Depending on the jurisdiction of the National Park, National
Park Service Law Enforcement can cite (ticket) you for either
violations of state or federal law. The three federal laws you
should review are: 36 CFR 4.2 (State law applicable)
36 CFR 4.21 (Speed Limits)
36 CFR 4.22 (Unsafe operation)
