Your question is backwards. While the Federal Constitution is an enabling document, meaning that the Federal Government only has the powers specifically granted to it, the State Constitutions are the opposite. The States generally have powers unless specifically limited by the State or Federal Constitutions. The state legislature has the power to make these laws, and the executive has the power to enforce them.
The state has the authority to enact reasonable laws for public safety.

US Constitution--none. It is not applicable to state highways laws. Additionally, the US Constitutions is specifically designed to address certain issues, issues left unaddressed are lef to the People/states to decide (see 10th Amendment--Bill of Rights.)
Your state Constitution likely has some provision regarding necessary and proper laws for public safety. Check it at http://www.leg.state.fl.us/statutes/index.cfm?mode=constitution&submenu=3
