Transporting bikes with trunk-mounted bike racks is a popular, affordable option for cyclists across the United States. However, understanding the legal requirements at both federal and state levels is essential to avoid fines, ensure safety, and stay compliant while traveling. This guide outlines key laws and practical tips for using trunk bike racks responsibly.

What Are Trunk Bike Racks?

Trunk bike racks attach to the rear of a vehicle using straps and hooks, offering a budget-friendly solution for bike transportation. These racks are compact, easy to install, and compatible with various vehicle types, including sedans, hatchbacks, and SUVs. They are particularly valued for their portability and simplicity, requiring no tools for installation in most cases.

Benefits of Using Trunk Bike Racks

• Affordability: Cost-effective compared to roof or hitch-mounted options.
• Ease of Use: Lightweight and quick to set up or remove.
• Versatility: Compatible with most vehicles, making them a universal solution.
• Storage Convenience: Compact design allows for easy storage when not in use.

Despite these advantages, it's crucial to follow specific regulations to ensure your bike rack usage remains within the law.
