Loading a car onto a trailer safely requires the right equipment, a solid plan, and careful execution. The core steps involve securing the trailer, using a proper approach ramp, driving or winching the car on slowly, and then thoroughly strapping it down. The most critical safety factor is using the correct number and type of tie-down straps, typically four, to secure the vehicle by its frame or designated tow points, not by the suspension or bumpers.
Before you begin, ensure your trailer is rated to handle the weight of your vehicle. The Gross Vehicle Weight Rating (GVWR) of the trailer must exceed the car's weight. Park the trailer on a level, solid surface and engage the trailer’s parking brake. Chock the trailer wheels front and back to prevent any movement.
Using the correct ramps is essential. Make sure they are rated for the weight and are securely attached. Drive the car onto the trailer slowly and in a straight line. If the vehicle is inoperable, a winch is necessary. Center the car on the trailer, and then shift the transmission into Park (for automatics) or gear (for manuals). Engage the parking brake.
Tie-downs are where many mistakes happen. Use ratchet straps with a minimum working load limit of 3,300 lbs each. Always attach straps to the vehicle’s frame or OEM tow hooks. Avoid strapping to control arms or axles, as this can lead to instability. The straps should form a 45-degree angle from the trailer deck to the car for optimal security. Compress the suspension slightly, but do not squash it completely. Finally, secure any loose parts, disconnect the battery if necessary, and double-check all connections before hitting the road.
| Critical Equipment & Specifications | Purpose & Importance |
|---|---|
| Trailer GVWR (e.g., 7,000 lbs) | Must exceed the combined weight of the car and trailer. |
| 4x Ratchet Straps (3,300 lb WLL each) | Securing the vehicle at four points provides balanced stability. |
| Wheel Chocks (Rubber or Metal) | Prevents trailer rollback during loading/unloading. |
| Approach Ramps (Weight-Rated) | Must support the vehicle's weight; critical for safe ascent/descent. |
| Safety Chains (Grade 70) | Provides a backup connection between the trailer and tow vehicle. |
| D-Rings or Anchor Points | Secure attachment points on the trailer deck for straps. |
| Winch (Capacity: 5,000+ lbs) | Essential for loading non-operational vehicles. |

Honestly, the scariest part is driving up that narrow ramp. Go super slow, have a spotter guide you, and keep the wheels straight. Once it's on, the real work begins with the straps. Don't just hook them to anything underneath—find the solid metal loops or frame points. Crank the straps down until the car's suspension compresses a tiny bit, but don't go crazy. Give the car a good shake; if it wobbles on the trailer, tighten it up more. A quick test drive around the block at low speed will tell you if everything is secure.

Safety is non-negotiable. The primary goal is to prevent any shift in the vehicle's center of gravity. This starts with trailer preparation: wheel chocks are mandatory. When securing the car, the angle of the straps is critical. A shallow angle provides less holding power, while too steep an angle can transfer excessive force. Aim for that 45-degree benchmark. Always perform a final inspection, tugging on each strap and checking that all hardware is locked. This methodical approach minimizes risk on the highway.

Let's break it down into three phases. Phase 1: Prep. Park the trailer on flat ground, chock the wheels, and check your ramp alignment. Phase 2: Load. Drive up slowly, straight as an arrow. Stop when all four wheels are firmly on the deck. Set the parking brake. Phase 3: Secure. This is the most important part. Cross your straps from the front left of the car to the right front of the trailer, and vice versa in the rear. This cross-pattern helps control sway. Ratchet until snug, do a walk-around, and you're set.
