Hauling a vehicle on an open trailer seems simple, but improper securement and weight distribution are the leading causes of trailer sway, accidents, and costly damage to both your tow vehicle and your car. Whether you’re moving a project car or a race car, safety and compliance are non-negotiable.
TrustyHaul builds open car trailers with heavy-duty tie-down points for maximum safety. Start hauling correctly with our reliable inventory: TrustyHaul Open Car Trailer Inventory.
1. Master the 60/40 Weight Distribution Rule
Proper balance is the single most critical factor in preventing dangerous trailer sway on the highway.
- The Rule: Position the vehicle so that 60% of the vehicle’s weight is located on the front half of the trailer deck, and 40% is on the rear.
- Tongue Weight: This ensures that 10% to 15% of the total loaded trailer weight (Gross Trailer Weight) is transferred to the tow vehicle’s hitch (tongue weight). Too little tongue weight causes the trailer to wander and sway dangerously at speed.
2. Mandatory Four-Point Securement
Federal regulations and common sense dictate that you must secure the vehicle at all four corners.
- Attachment Points: Secure your vehicle at four separate points—one near each wheel. The best points are the axles, the lower control arms, or the frame, as these are the strongest, most stable components.
- Low and Opposing Angles: Ensure your straps or chains pull the vehicle down and slightly outward against the trailer deck. This prevents both vertical bounce and lateral shift.
3. Choose the Right Tie-Down Method
The type of vehicle you haul dictates the best securement method.
- Wheel Nets: Recommended for modern or classic cars. Wheel nets cradle the tire and hold the vehicle securely without compressing the suspension, allowing the car to ride on its own shocks and springs.
- Axle Straps/Soft Loops: If securing to the frame or axle, use soft axle straps or high-quality soft loops. These protect the vehicle’s finish and suspension components from direct metal-on-metal abrasion that chains can cause. Avoid securing a vehicle by its bumper or tie rod ends.
4. Pre-Trip Tire and Brake Check
Always check the tires and braking system on the trailer, not just the tow vehicle, before you leave.
- Trailer Tire PSI: Check the tire pressure (PSI) on all trailer tires when they are cold. Ensure the pressure matches the maximum PSI listed on the tire sidewall. Under-inflated trailer tires are a leading cause of blowouts.
- Brake Connection: If your trailer is equipped with electric brakes (mandatory on larger models), ensure the wiring harness is properly connected and the brake controller inside your tow vehicle is functional and set correctly. The trailer brakes do a majority of the stopping for the loaded weight.
5. Clear the Deck and Lock the Doors
A clean deck and secured cabin prevent damage during transit.
- Remove Loose Items: Clear the car’s interior of anything that could become a projectile, and ensure the vehicle’s hood, trunk, and any toolboxes are securely latched or locked.
- Spare Tire: If your trailer has a spare tire mount, ensure the spare is fully inflated and accessible in case of a roadside emergency.
Safety is the best investment you can make when hauling. By following these five rules, you ensure a safe, smooth, and legal journey for both your tow vehicle and your cargo.
