If you’ve noticed a red line on the sides of your trailer, you’re looking at a simple but effective tool designed to prevent one of the most frequent and costly accidents in trucking. Here’s what the red line is, why it’s there, and how to use it to protect your equipment and stay safe.
A Costly Problem: Damaged Wing Extenders
Every year, drivers damage wing extenders and brackets by turning too tightly or backing and jacking the trailer too hard. Each incident can cost approximately $2,000 per side to repair. These preventable accidents not only lead to expensive repairs but also take drivers off the road and into the shop.
The Purpose of the Red Line
To address this issue, red lines have been added to both sides of trailers as a visual guide when backing into docks.
- How It Works:
As you back up, the red line remains visible in your mirror. Once the red line disappears, it’s a signal that you’re too close to the trailer. Proceeding further risks damaging the wing extenders and brackets. - The Safety Buffer:
When the red line disappears from view, there are approximately 6 to 8 inches of space between the tractor and the trailer. This cushion gives you the chance to:- G.O.A.L. (Get Out and Look): Exit the cab and check your alignment.
- Reposition Safely: Pull forward and adjust your backing angle.
Why the Red Line Matters
- Prevents Equipment Damage: Using the red line as a guide helps avoid costly repairs to wing extenders and brackets.
- Keeps You on the Road: Less time in the shop means more time driving and earning.
- Encourages Safe Practices: It’s a visual reminder to slow down, assess your position, and avoid rushing during tight maneuvers.
How to Use the Red Line Effectively
- Monitor Your Mirrors: As you back into the dock, keep an eye on the red line in your side mirrors.
- Watch for Disappearance: Once the red line disappears, stop immediately.
- Take Action: Use the opportunity to G.O.A.L. or reposition your tractor to ensure safe alignment.
- Stay Consistent: Make checking the red line part of your standard backing routine.
A Safer, Smarter Backing Experience
The red line isn’t just a cost-saving tool; it’s a safety feature that protects your equipment, keeps you on schedule, and minimizes stress. By using the red line as a benchmark, you can confidently back into docks without risking damage.
