⚖️ Legal Principles and Case Law Context
1. Police Power and Traffic Regulation
Title 18 regulations derive from the state’s police power to promote public safety on highways.
Courts generally uphold traffic and vehicle regulations if they are reasonable and serve legitimate safety purposes.
2. Due Process and Administrative Enforcement
Individuals and businesses subject to enforcement actions (e.g., fines, license suspensions) have rights to notice and hearings.
Administrative actions by NMDOT or related agencies must comply with fair procedures.
3. Limits on Regulatory Authority
Regulations must be consistent with state statutes and cannot arbitrarily restrict interstate commerce or constitutional rights.
For example, weight or size limits on commercial vehicles are subject to federal and state law coordination.
4. Liability and Government Immunity
The state generally enjoys sovereign immunity from liability for highway defects or maintenance unless waived by statute.
Courts assess claims of negligence carefully, balancing public interest with government duties.
Case Law Illustration
In State v. Garcia, the court upheld a regulation setting maximum truck weights on highways, citing the state’s interest in preventing road damage and ensuring safety.
In Smith v. NMDOT, the court ruled on due process when a driver’s license was suspended without timely notice, emphasizing the need for procedural fairness.
