The absolute maximum speed you should travel with a 5×8 U-Haul trailer is 55 mph (88.5 km/h). This speed limit is strictly enforced by U-Haul and outlined in their rental agreement. Exceeding this speed not only violates the terms of your contract but also significantly increases the risk of accidents and compromises your safety, and the safety of others on the road.
Why 55 MPH? The Science Behind the Speed Limit
The 55 mph speed limit for U-Haul trailers isn’t arbitrary. It’s a calculated figure based on a multitude of factors crucial to safety and trailer performance. Understanding these factors provides valuable context for adhering to the speed limit.
- Aerodynamics and Stability: Trailers, especially smaller ones like the 5×8, can experience significant wind resistance and instability at higher speeds. The design and construction of these trailers are optimized for safe handling within the specified speed range. Exceeding 55 mph can lead to trailer sway, a dangerous condition where the trailer oscillates uncontrollably, potentially resulting in loss of control.
- Braking Distance: Increasing speed dramatically increases the braking distance required to safely stop. A loaded trailer further compounds this effect. At higher speeds, even a slight misjudgment or sudden obstacle can become a critical situation. The 55 mph limit allows for a more manageable braking distance, providing drivers with crucial reaction time.
- Tire Integrity: U-Haul trailers utilize tires designed for specific load ratings and speed tolerances. Exceeding the 55 mph limit can subject these tires to excessive stress and heat buildup, increasing the risk of tire blowouts. A tire blowout while towing is extremely dangerous and can easily lead to an accident.
- Vehicle Handling: Towing a trailer significantly alters the handling characteristics of the tow vehicle. Acceleration, braking, and cornering all become more challenging. The 55 mph limit is chosen to maintain a reasonable level of control and predictability for the driver, even under adverse conditions.
- Liability and Legal Implications: Should an accident occur while exceeding the speed limit, U-Haul is likely to deny liability coverage. The renter would be held fully responsible for all damages and injuries, potentially facing significant financial burdens.
Factors Affecting Safe Towing Speed
While 55 mph is the maximum limit, the optimal speed for towing may be lower depending on several variables. These factors should be carefully considered before and during your trip:
- Weather Conditions: Rain, snow, ice, and high winds drastically reduce traction and visibility. In these conditions, significantly reducing speed is essential. Driving at 55 mph in heavy rain is inherently unsafe, regardless of the posted speed limit.
- Road Conditions: Rough or uneven road surfaces can cause the trailer to bounce and sway, making it more difficult to control. Lowering your speed provides a smoother ride and enhances stability.
- Load Weight and Distribution: An improperly loaded trailer is a recipe for disaster. Ensure the load is evenly distributed, with heavier items placed closer to the axle. Overloading the trailer increases stress on the tires and suspension, requiring reduced speeds. Consult the U-Haul weight limits and guidelines carefully.
- Driver Experience: Towing a trailer requires skill and experience. Novice towers should be extra cautious and drive well below the speed limit, especially in challenging conditions. Practicing in a safe, open area before embarking on a long journey can be invaluable.
- Tow Vehicle Capacity: Your tow vehicle must be appropriately rated to handle the weight and size of the 5×8 U-Haul trailer. Consult your vehicle’s owner’s manual to determine its towing capacity and ensure it is not exceeded.
Frequently Asked Questions (FAQs)
FAQ 1: What happens if I get caught speeding with a U-Haul trailer?
You will receive a speeding ticket, just like you would in any vehicle. More significantly, violating U-Haul’s speed limit (55 mph) may void your rental agreement and insurance coverage. You could be held liable for any damages or injuries resulting from an accident.
FAQ 2: Can I use cruise control while towing a U-Haul trailer?
While cruise control can be convenient, it’s generally not recommended while towing a U-Haul trailer. Road conditions can change rapidly, and cruise control may not react appropriately to sudden changes, such as hills or curves. Maintaining manual control allows for quicker and more responsive adjustments to your speed.
FAQ 3: Does the 55 mph speed limit apply in all states?
Yes, the U-Haul 55 mph speed limit applies regardless of the posted speed limit on the road. Even if a highway has a 70 mph speed limit, you are still required to adhere to the U-Haul’s 55 mph restriction when towing their trailer.
FAQ 4: What if I’m going downhill? Should I slow down even more?
Absolutely. Going downhill increases the strain on your brakes and can cause the trailer to accelerate. Reduce your speed significantly when descending hills, especially steep ones. Consider using a lower gear to help control your speed and minimize brake usage.
FAQ 5: How can I prevent trailer sway?
- Ensure the trailer is properly loaded with even weight distribution.
- Maintain a safe following distance.
- Reduce your speed, especially in windy conditions.
- If sway occurs, gently apply the trailer brakes (if equipped) and gradually reduce speed. Avoid sudden braking or steering adjustments.
- Consider installing a sway control device for added stability.
FAQ 6: What are the weight limits for a 5×8 U-Haul trailer?
The empty weight (tare weight) is approximately 850 lbs. The maximum gross weight (trailer plus load) is 2,700 lbs. This means you can carry a maximum of 1,850 lbs. Check the sticker on the trailer for the exact specifications.
FAQ 7: Where can I find the U-Haul rental agreement rules regarding speed?
The U-Haul rental agreement explicitly states the 55 mph speed limit. It’s crucial to read and understand the entire agreement before operating the trailer. This information can usually be found in the “Terms and Conditions” section.
FAQ 8: What happens if I need to brake suddenly while towing?
Brake gently and progressively, avoiding abrupt stops. Allow for a significantly longer braking distance than you would when driving without a trailer. If your vehicle is equipped with trailer brakes, use them in conjunction with your vehicle’s brakes. Practice emergency braking in a safe area before your trip.
FAQ 9: Should I inflate the trailer tires to a specific pressure?
Yes. The recommended tire pressure is usually listed on the sidewall of the tire or on a sticker on the trailer. Ensure the tires are inflated to the correct pressure before each trip. Underinflated tires can lead to overheating and blowouts.
FAQ 10: How do I properly load a 5×8 U-Haul trailer?
Place heavier items at the front of the trailer, near the axle. Distribute the weight evenly from side to side. Secure all items with straps, ropes, or tie-downs to prevent shifting during transit. Avoid stacking items too high, as this can affect the trailer’s center of gravity.
FAQ 11: What maintenance checks should I perform before towing a U-Haul trailer?
- Inspect the tires for proper inflation, wear, and damage.
- Check the lights (brake lights, turn signals, and running lights) to ensure they are functioning correctly.
- Verify that the hitch and safety chains are securely connected.
- Inspect the trailer’s coupler for wear and damage.
- Check the wheel bearings for excessive play or noise.
FAQ 12: Are there any specific laws regarding towing in different states?
Yes, towing laws vary by state. These laws can cover topics like speed limits, lane restrictions, required equipment (such as mirrors and mud flaps), and maximum trailer dimensions. Research the towing laws in each state you will be traveling through to ensure compliance. The DMV website of each state should have this information available.
Conclusion: Safety First, Always
While reaching your destination quickly may be tempting, prioritizing safety is paramount when towing a U-Haul trailer. Adhering to the 55 mph speed limit, carefully considering road conditions, and properly loading and maintaining the trailer will significantly reduce the risk of accidents and ensure a safe and successful move. Remember, arriving safely is far more important than arriving quickly.
