Which of the following is a traffic law that can be enforced on private property?

The correct answer is that hit and run can be enforced on private property because it involves the unlawful action of leaving the scene of an accident without providing the necessary information or assistance. This type of violation is serious and can have legal consequences regardless of whether the incident occurs on public or private property. Law enforcement has the authority to investigate such incidents on private property, particularly when they involve personal injury or significant property damage.

While driving without a license, speeding violations, and unauthorized parking are also offenses, they typically relate more directly to public roads and traffic regulations enforced by public authorities. Speeding violations are based on public safety laws that specifically apply to public roadways, where speed limits are established for the welfare of all drivers. Driving without a license is strictly a public roadway issue, and unauthorized parking may not always be enforceable in the same way on private property unless specific property rules or local ordinances are in place to support such enforcement.
