Knowing how to properly tie down a car on a rollback is one of the most fundamental skills in towing — and one of the most commonly done wrong. A loose load doesn't just risk damage to the vehicle; it's a DOT violation, a liability, and in a worst case, a hazard to everyone on the road behind you.
This guide covers the full procedure from pre-load inspection through final departure check, with the equipment list and the common mistakes that get operators written up or worse.
Before You Load: Pre-Trip Equipment Inspection
Don't load the vehicle until you've confirmed your securement gear is in working order. A strap pulled from the count at the roadside because it's frayed or missing its WLL label is a strap that wasn't doing its job anyway.
Check every strap you plan to use:
- Webbing is free of cuts, fraying, abrasion, and chemical contamination
- WLL label is present and legible — if it's missing, that strap doesn't count toward your aggregate WLL requirement
- Ratchet pawl engages and locks cleanly
- Snap hook keeper closes fully and springs back into position
- Hook throat is not bent or deformed
Check your deck:
- Tie down rails or floor rings are undamaged and secure
- No cracked welds or bent sections at anchor points
- Deck surface is clear — no debris that could damage the towed vehicle's undercarriage
Check the vehicle being loaded:
- Note the weight — you need it to calculate required WLL
- Identify usable tie down points: manufacturer-installed loops, frame sections rated for securement, or wheel contact points
- Note any damage present before loading so it's documented
Step 1: Position the Vehicle on the Deck
Back the rollback down to the appropriate angle and load the vehicle so it's centered on the deck, left to right. A vehicle sitting off-center shifts the load distribution and increases lateral stress on the straps on the heavy side.
Direction: Load the vehicle facing forward — front of the towed vehicle toward the cab of the rollback — whenever possible. This puts the vehicle's heaviest component (the engine) over the front axle area of the deck and keeps the vehicle's natural braking weight bias working in your favor during hard stops.
If you're loading a rear-wheel-drive vehicle that's inoperable and must be winched on backwards, note it in your documentation. The tie down procedure is the same either way — what changes is which end you're calling the "front" for anchor point purposes.
Once positioned:
- Engage the parking brake on the towed vehicle if it's operable
- Place the transmission in Park if automatic, or in gear if manual
- Chock the wheels if the vehicle will be in neutral for any reason
Step 2: Identify Your Anchor Points
This is where most mistakes happen. Not every point on a vehicle that looks sturdy is a rated tie down anchor.
Acceptable anchor points on the towed vehicle:
- Manufacturer-installed tie down loops or hooks (found on most vehicles, typically near the wheels inside the wheel well or on the frame rails)
- Solid frame sections — the main frame rails on trucks and body-on-frame vehicles
- Axle housings (for axle strap applications)
- Wheels and tires (for over-wheel strap applications)
Do not anchor to:
- Suspension components (control arms, sway bars, strut housings) — these are not rated for lateral tie down loads and can be damaged or bent
- Plastic body panels or bumper covers
- Exhaust components
- Steering linkage
- Brake lines or fuel lines
When in doubt on a passenger car with no visible frame tie down loops, over-the-wheel straps are your safest option — they put the load on the tire and wheel, which are engineered to handle it, rather than on body or suspension components.
Anchor points on the rollback deck:
Use the tie down rail slots or floor rings closest to each wheel position. The goal is a strap path that runs at an angle — not straight down vertically — so the strap is pulling the vehicle down and toward the anchor simultaneously. A strap running perfectly vertical has no forward/rearward restraint component.
Step 3: Set Your 4-Point Tie Down
A standard 4-point setup places one strap at each corner of the vehicle — front left, front right, rear left, rear right. This is the baseline compliant setup for passenger vehicles and light-duty trucks on a rollback.
Strap routing for each point:
- Hook one end of the strap to the deck anchor point
- Route the strap up and over (or through) the wheel/frame anchor on the vehicle
- Run the strap at an angle toward the center of the deck — not straight up — so it has a forward or rearward pull component in addition to downward
- Hook the other end to a second deck anchor point, or back to the ratchet body mounted on the rail
- Feed the webbing through the ratchet spool and take up initial slack by hand before ratcheting
Front straps should angle slightly rearward — pulling the front of the vehicle down and back toward the deck.
Rear straps should angle slightly forward — pulling the rear of the vehicle down and forward.
This opposing angle setup creates a crisscross tension pattern that resists both forward surge (braking) and rearward shift (acceleration), as well as lateral movement.
Tensioning:
Ratchet each strap until the webbing is taut and the vehicle visibly compresses slightly at each tie down point. You should not be able to create slack by pushing up on the strap. Do not overtighten to the point of distorting the vehicle's body or suspension geometry — firm and taut, not wrenched down.
Once tensioned, close and lock each ratchet handle. Secure excess webbing so it's not hanging loose or dragging.
Step 4: When to Use an 8-Point Setup
A 4-point setup is compliant for most passenger vehicle tows. Step up to an 8-point setup when:
- The vehicle weighs over 7,500 lbs (the math may push you past what 4 standard straps cover)
- You're running a long haul — interstate transport, multi-hour runs
- The vehicle is a high-value or exotic that warrants extra securement
- DOT inspection risk is elevated — commercial corridors, weigh station routes
- The vehicle has no factory tie down loops and you're relying solely on over-wheel straps, where additional points provide better load distribution
An 8-point kit adds four additional strap points — typically at the axles or additional frame locations — beyond the four corner points. It increases your aggregate WLL and distributes the load more evenly across the vehicle.

Step 5: Verify WLL Compliance
Before you close the ratchets and call it done, run the math.
The FMCSA rule (49 CFR 393.102): Your combined WLL of all straps must equal at least 50% of the cargo weight.
Required Combined WLL = Vehicle Weight × 0.50
Example: You're loading a Ford F-150 at approximately 5,500 lbs.
- Required combined WLL: 5,500 × 0.50 = 2,750 lbs minimum
- Four 2" ratchet straps at 3,333 lb WLL each = 13,332 lbs combined
- You're well over the requirement
Where operators get caught: a vehicle that's heavier than assumed, or straps that are worn or unlabeled and can't be counted. Know your cargo weight and count only straps in good condition with legible WLL labels.

Step 6: Final Pre-Departure Check
With everything strapped and tensioned, do a full walk-around before you move:
- All four straps tensioned and ratchet handles locked
- Excess webbing tails secured — none hanging loose or dragging on the deck
- Vehicle does not rock or shift when you push firmly on the bumper
- All tires fully on the deck — no tire hanging over the edge
- No part of the towed vehicle is contacting the cab of the rollback
- Clearance lights and reflectors on the rollback are not blocked by the cargo
- Any loose components on the towed vehicle (hoods, doors, trunks) are secured or noted
If anything moves when you push on the bumper, the vehicle is not immobilized. Add a strap or recheck routing and tension before leaving.
En-Route Re-Inspection
49 CFR 392.9 requires you to stop and re-check cargo securement within the first 50 miles of the trip and after any change in cargo. For most local tows this means one check at your first stop or at the yard.
What to check:
- Strap tension — straps can settle slightly after initial loading, especially on vehicles with soft rubber bushings at contact points
- Ratchet handles still locked
- No new webbing damage from contact with vehicle edges during transit
Two minutes at the first stop. It's a federal requirement, not optional.
Common Mistakes That Cause Load Shifts and DOT Violations
Anchoring to suspension components. Control arms, strut housings, and sway bar end links look solid but are not rated for tie down loads. A strap pulling laterally on a control arm can bend it. Use frame rails, factory tie down loops, or wheel/axle contact points.
Running straps straight vertical. A vertical strap prevents the vehicle from lifting off the deck but provides almost no forward or rearward restraint. Angle your straps so they have a horizontal component.
Skipping the WLL math. Four straps is not automatically compliant — it depends on the WLL of those four straps versus the weight of the cargo. Count only labeled, undamaged straps. Run the 50% calculation.
Using a strap with a missing or unreadable label. No label means no verifiable WLL. A DOT inspector will not count it toward your aggregate. You may have three compliant straps and one decoration.
Not securing excess webbing. Loose webbing tails flapping at highway speed can wrap around components, contact the road surface, or create a visual distraction. It's also a citable violation under 49 CFR 393.104.
Skipping the post-load push test. If you don't test immobilization before you leave, you won't know the vehicle is shifting until it's moved.
Not doing the 50-mile re-check. Most operators know about this rule and skip it anyway. If you're stopped and can't say when you last checked your securement, that's a citable answer.
Equipment for a Proper Rollback Setup
Standard passenger vehicle load — 4-point setup:
4 × 2" ratchet straps, 3,333 lb WLL, snap hooks or chain ends depending on your anchor point configuration. This covers every passenger vehicle and light-duty truck under about 10,000 lbs with significant compliance margin.
Heavier loads or long hauls — 8-point setup:
8-point carrier tie down kit with chain ends. Gives you eight securement points, higher aggregate WLL, and a more organized setup than assembling eight individual straps.
Vehicles with no factory tie down loops:
Over-wheel straps or axle straps route around the tire or axle housing rather than connecting to a fixed vehicle point. Designed specifically for this application.
Edge protection:
If any strap routing requires the webbing to contact a sharp body edge or frame section, use a strap protector sleeve or edge guard at the contact point. Unprotected contact with a sharp edge cuts through webbing under load.
