True or False: A straight truck-trailer combination that exceeds 65 ft may not be driven on public highways without a special permit.

The statement is true because regulations regarding the length of truck-trailer combinations vary by state and local jurisdiction. In general, most public highways have specific length restrictions for commercial vehicles to ensure safety and reduce road congestion. A straight truck-trailer combination that exceeds 65 feet typically requires a special permit to operate legally on public highways. This requirement is put in place to manage the potential risks and challenges that can arise from larger vehicles, such as increased stopping distances and maneuverability issues.

While some states may have different regulations, the overarching guideline is that exceeding this length often necessitates obtaining special permits to prevent disruption of traffic flow and to enhance safety for all road users. Hence, the answer is correct as it aligns with conventional traffic regulations governing large vehicle operations.
