Knowing precisely where to weigh your trailer is paramount for safe and legal towing, preventing accidents and avoiding costly penalties. Accurately determining your trailer’s weight, both empty (tare weight) and loaded (gross weight), allows you to ensure you’re within your tow vehicle’s capacity and adhering to weight regulations.
Why Weighing Your Trailer Matters
Towing a trailer without knowing its weight is akin to driving blindfolded. It introduces significant risks, jeopardizes the safety of yourself and others on the road, and can lead to severe legal repercussions. Overloading your tow vehicle or trailer can cause:
- Reduced braking performance: Longer stopping distances, especially in emergency situations.
- Compromised steering: Difficulty maintaining control, particularly on winding roads or in adverse weather.
- Damage to vehicle components: Premature wear and tear on tires, suspension, axles, and brakes.
- Rollover accidents: An increased risk, particularly with high-profile trailers like travel trailers or campers.
- Legal penalties: Fines and potential impoundment of your vehicle and trailer for exceeding weight limits.
Beyond the safety aspects, knowing your trailer’s weight is essential for:
- Proper weight distribution: Balancing the load to prevent sway and maintain stability.
- Choosing the right tow vehicle: Ensuring your vehicle has the necessary towing capacity.
- Insurance coverage: Providing accurate information to your insurance provider.
Finding the Right Weighing Location
The best place to weigh your trailer will depend on your location, the type of trailer you have, and the availability of appropriate weighing equipment. Here are some common options:
Commercial Weigh Stations
Commercial weigh stations, often found along major highways and interstates, are primarily designed for weighing large trucks and commercial vehicles. While they may seem intimidating, many are equipped to handle smaller vehicles and trailers, often for a small fee. Calling ahead to confirm their policy on weighing private trailers is always recommended. These stations offer calibrated scales and often provide printed weight tickets, which serve as official documentation of your trailer’s weight.
Public Scales (Truck Stops)
Truck stops often have certified public scales that are accessible to anyone willing to pay a small fee. These scales are generally well-maintained and accurate. Look for truck stops with scales specifically designed for weighing vehicles, including those pulling trailers. These scales usually have platforms long enough to accommodate the entire length of your rig.
Recycling Centers and Scrap Yards
Recycling centers and scrap yards frequently utilize scales to weigh materials being brought in. While not always certified, these scales can provide a reasonably accurate weight reading, particularly for empty trailers. However, verify the scale’s calibration and reliability before relying on its readings. This option is more suited for getting the tare weight of your trailer.
Agricultural Supply Stores and Grain Elevators
Agricultural supply stores and grain elevators often have scales for weighing agricultural products and equipment. Similar to recycling centers, these scales may not be specifically designed for vehicles, but they can provide a useful estimate of your trailer’s weight. Again, confirm the scale’s calibration and suitability for weighing vehicles beforehand.
Portable Scales
Portable scales are a convenient option for weighing your trailer at home or in a remote location. These scales are typically placed under the wheels of the trailer and provide a digital weight reading. While portable scales offer convenience, it’s crucial to choose a high-quality, certified model and follow the manufacturer’s instructions carefully to ensure accuracy. Ensure the ground is level when using portable scales for accurate readings.
Essential Tips for Weighing Your Trailer
- Empty the trailer: Whenever possible, weigh your trailer empty to determine its tare weight accurately.
- Level the trailer: Ensure the trailer is level when being weighed, as an uneven surface can skew the readings.
- Disconnect from the tow vehicle: For the most accurate weight, disconnect the trailer from the tow vehicle.
- Weigh each axle: Weighing each axle separately can help you identify potential weight distribution issues.
- Document the weight: Keep a record of the weight readings, including the date, time, and location of the weighing.
Frequently Asked Questions (FAQs)
1. What is GVWR and why is it important?
GVWR stands for Gross Vehicle Weight Rating, and it’s the maximum permissible weight of your trailer, including its own weight plus the weight of cargo, fluids, and passengers (if applicable). Exceeding the GVWR is illegal and unsafe. It’s usually found on a sticker or plate on the trailer.
2. How do I find the tare weight of my trailer if I can’t weigh it empty?
While weighing empty is ideal, you can often find the tare weight (also known as unladen weight) on the trailer’s VIN plate or in the manufacturer’s documentation. Remember this is the weight before any modifications or additions.
3. What happens if I’m caught towing an overloaded trailer?
Penalties vary by state and jurisdiction, but can include fines, impoundment of your vehicle and trailer, and even legal liability in the event of an accident.
4. Can I use a bathroom scale to weigh my trailer’s tongue weight?
While a bathroom scale can provide a rough estimate, it’s not accurate enough for ensuring safe towing. Use a dedicated tongue weight scale designed for this purpose. These scales are readily available online and at RV supply stores.
5. How often should I weigh my trailer?
Weigh your trailer whenever you significantly change its contents or load configuration, especially before long trips. Also, weigh it when you first acquire the trailer to confirm the manufacturer’s stated tare weight.
6. What is tongue weight and why is it important?
Tongue weight is the amount of weight the trailer exerts on the hitch of the tow vehicle. It should typically be between 10-15% of the trailer’s gross weight for optimal stability. Too little or too much tongue weight can cause trailer sway.
7. How can I adjust the weight distribution in my trailer?
To adjust weight distribution, move heavier items forward or backward within the trailer. Avoid placing heavy items at the very rear of the trailer, as this can exacerbate sway. Aim for a balanced load with the heaviest items positioned over or slightly ahead of the trailer axles.
8. What are weight distribution hitches and how do they help?
Weight distribution hitches distribute the tongue weight of the trailer more evenly across the axles of the tow vehicle. This improves handling, braking, and overall stability, especially when towing heavier trailers.
9. Do I need a special license to tow a trailer?
Requirements vary by state and the combined weight of your tow vehicle and trailer. Check your local Department of Motor Vehicles (DMV) or transportation agency for specific regulations. Some states require a Commercial Driver’s License (CDL) for towing certain types of trailers or exceeding specific weight limits.
10. Is it legal to weigh my trailer on a public road using portable scales?
Generally, weighing your trailer on a public road is illegal and unsafe. It’s best to use designated weighing locations or a private property. Check with your local authorities for specific regulations.
11. What does “dry weight” mean for travel trailers?
Dry weight refers to the weight of the travel trailer as it leaves the factory, without fluids (water, propane), cargo, or optional equipment. It’s important to remember that the dry weight is just a starting point; the actual weight will be higher once you add your belongings.
12. How can I find certified scales near me?
You can search online for “certified scales near me” or contact your local Department of Transportation or trucking association for a list of certified weighing locations. Resources like the National Conference on Weights and Measures can also be helpful.
By taking the time to properly weigh your trailer and understanding the associated weight regulations, you can ensure a safer and more enjoyable towing experience. Remember, safety should always be your top priority.
