Updated: November 23, 2025 8 min read Tennessee Law Guide

🚨 TENNESSEE LAW ALERT

Brake controllers are REQUIRED by Tennessee law for trailers over 1,500 lbs GVWR

Violation Penalty: Fines up to $500 + court costs. Don't risk it - ensure compliance before you tow!

🎛️ What Is a Brake Controller?

A brake controller is an electronic device installed in your tow vehicle that activates and controls the electric brakes on your trailer. Think of it as the "brain" that coordinates braking between your truck and trailer for maximum safety and control.

🔧 How Brake Controllers Work

✓ Detects braking: Senses when you press your vehicle's brake pedal
✓ Sends signal: Transmits electrical current to trailer brakes
✓ Controls intensity: Adjusts braking force based on your settings
✓ Synchronizes stopping: Ensures smooth, coordinated braking

📋 Tennessee Brake Controller Requirements

✅ REQUIRED

• Trailers over 1,500 lbs GVWR
• All electric brake systems
• Commercial trailers
• Rental trailers (like ours!)

⚠️ RECOMMENDED

• Trailers 1,000-1,500 lbs
• Surge brake systems
• Frequent towing
• Mountain/hill driving

🔍 Types of Brake Controllers

1. Proportional Brake Controllers (RECOMMENDED)

How they work: Use internal sensors to detect your vehicle's deceleration and apply trailer brakes proportionally.

✅ Advantages:

Smoother, more natural braking
Better for heavy trailers
Reduces wear on brakes
Improved safety and control

⚠️ Considerations:

Higher initial cost
More complex installation
Requires level mounting

2. Time-Delayed Brake Controllers

How they work: Apply trailer brakes at a preset time delay and intensity after your vehicle's brakes are applied.

✅ Advantages:

Lower cost
Simpler installation
Good for light trailers
Easy to adjust

⚠️ Considerations:

Less smooth braking
Not ideal for heavy loads
More brake wear
