Towing a car on a flatbed trailer is one of the most common — and most misunderstood — tasks in towing. Done right, it’s safe, predictable, and relatively straightforward. Done wrong, it can result in a vehicle that slides off during transit, a trailer that sways uncontrollably, or a hitch setup that’s completely overloaded. Whether you’re moving a non-runner, hauling a classic car to a show, or helping a friend after a breakdown, this guide will walk you through everything you need to know.
What You’ll Need: Equipment Checklist
Before you load a single car, make sure you have the right equipment. Improvising on vehicle transport is how serious accidents happen.
Step 1: Set Up the Trailer
Position the trailer on a flat, level surface. If it’s a tilt-deck or dovetail trailer, confirm the deck is locked in the down (loading) position and is resting securely on the ground before you try to drive or push a vehicle onto it. Chock the trailer tires so it doesn’t roll during loading. Make sure the trailer is connected to your tow vehicle before loading begins — an unhitched trailer can tip backward under the weight of the car if the center of gravity shifts.
Step 2: Position the Car Correctly on the Trailer
Positioning matters enormously for tongue weight and sway prevention. The goal is to achieve proper tongue weight — approximately 10–15% of the total loaded trailer weight. On most flatbed trailers, loading the car as far forward as possible (within the deck space) creates better tongue weight. An imbalanced load with too much weight behind the axle will create dangerous sway conditions. For more on weight distribution principles, see our guide on Trailer Weight Distribution.
Step 3: Apply Wheel Straps or Axle Straps
Use four straps: two at the front and two at the rear. The straps should pull outward and downward at approximately a 45-degree angle — this creates compression force on the suspension, which helps keep the car planted on the trailer deck. Each strap should be rated for at least 3,333 lbs working load limit (WLL) if you’re using four straps on a 5,000 lb car.
Do not hook straps to suspension arms, brake lines, fuel lines, steering components, or any part of the underbody that wasn’t engineered for tie-down loads.
Step 4: Tension the Straps Correctly
Tighten each strap firmly with the ratchet mechanism. The tires should compress slightly under the strap tension — this is normal and desired. You should not be able to pull significant slack from any strap by hand. Engage the parking brake on the vehicle if possible. If the vehicle has an automatic transmission, leave it in Park. Manual transmissions can be left in gear.
Step 5: Do a Final Inspection Before Pulling Out
Walk around the entire rig and verify: all four straps are tensioned, no strap is riding on a sharp edge, wheel chocks are secured or removed, the trailer hitch is properly connected, safety chains are crossed and attached, and trailer lights are working. Review the full Pre-Trip Towing Checklist before every load.
On the Road: Driving Tips for Car-Loaded Flatbeds
A flatbed trailer loaded with a car handles differently than an empty trailer. The load raises the center of gravity significantly and adds momentum that affects braking and cornering. Reduce your highway speed by at least 10 mph from your normal towing speed. Allow significantly longer following distance — stopping a loaded flatbed takes much longer than stopping a car. Take turns and on-ramps slowly and smoothly.
Check your straps at every fuel stop, especially on the first stop after loading. Vibration and settling during the first 30–50 miles can cause strap tension to decrease. Re-tighten any straps that have loosened. This is a habit professional auto haulers never skip.
Common Mistakes to Avoid
Using too few straps is the most common error — four straps is the minimum for any passenger vehicle. Hooking straps to non-structural points on the vehicle’s underbody is the second most common mistake and can cause thousands of dollars in damage. Loading the car too far back on the trailer (creating rear-heavy weight distribution) is a frequent cause of dangerous sway on flatbed loads. And skipping the strap tension check mid-trip is how loads arrive shifted or damaged.
The Bottom Line
Towing a car on a flatbed trailer is straightforward when you follow the right sequence: set up the trailer correctly, load the car forward-biased for proper tongue weight, use four properly rated straps in a pull-down-and-out orientation, tension them firmly, and check them throughout the trip. The same principles of weight distribution, trailer sway prevention, and pre-trip inspection that apply to all towing apply here — just with a heavier, less forgiving load.
