Overview of Tennessee Title 1680 — Transportation
Title 1680 governs the administrative rules, standards, and procedures related to transportation within Tennessee. This encompasses regulations issued by the Tennessee Department of Transportation (TDOT) and related authorities, covering highways, public transit, commercial motor vehicles, safety regulations, and infrastructure development.
1. Scope and Purpose
Title 1680 aims to ensure safe, efficient, and lawful operation of Tennessee’s transportation systems.
It covers highway design and maintenance, traffic regulations, commercial vehicle operation, public transit oversight, and transportation planning.
These rules serve to protect public safety, facilitate commerce, and maintain the infrastructure.
2. Highway and Infrastructure Regulations
Key Provisions:
Design standards for road construction and maintenance.
Rules regarding weight limits, load restrictions, and vehicle sizes on state highways.
Regulations for permits required for oversized or overweight vehicles.
Procedures for right-of-way acquisition and eminent domain related to transportation projects.
Case Law:
In Tennessee Department of Transportation v. Ford, the Tennessee Supreme Court upheld the state's authority to acquire private land for highway construction via eminent domain, emphasizing the state's police power and public use doctrine.
Weight and size limits have been enforced under Tennessee’s Vehicle Size and Weight Law. In State v. Smith, the court affirmed penalties imposed on commercial operators violating weight restrictions, noting the state's interest in preserving infrastructure.
3. Commercial Motor Vehicle Regulations
Key Provisions:
Operators of commercial vehicles must comply with licensing, safety inspections, and operational rules.
Rules include hours of service limits to prevent driver fatigue.
Compliance with hazardous materials transportation regulations.
Requirements for vehicle registration, insurance, and safety standards.
Case Law:
The U.S. Supreme Court’s decision in Garcia v. San Antonio Metropolitan Transit Authority established federal preemption in commercial vehicle regulation, but Tennessee’s rules still apply to intrastate operations and supplement federal laws.
In Tennessee v. Johnson, a trucking company challenged a vehicle inspection citation, but the court ruled that state inspection requirements are valid exercises of the state’s police power.
4. Traffic Control and Enforcement
Key Provisions:
Rules on traffic signals, signs, speed limits, and lane usage.
Enforcement authority granted to state and local law enforcement.

Key Provisions:
Regulation of public transit agencies and services.
Rules regarding passenger safety, fare collection, and service accessibility.
Requirements for transit vehicle maintenance and driver qualifications.
Case Law:
Courts have recognized the state’s role in overseeing transit systems as a public service. For instance, in Metropolitan Transit Authority v. Johnson, the court held that transit authorities have sovereign immunity in tort claims unless waived by statute.
6. Transportation Planning and Funding
Key Provisions:
Procedures for developing statewide and regional transportation plans.
Guidelines for allocating federal and state funds.
Requirements for environmental assessments and public input.
