Quick Answer
A trailer hitch is the receiver mounted to a vehicle’s frame for pulling a trailer; in the UK and Australia the same thing is called a tow bar. In the US, ‘tow bar’ usually means the A-frame or telescoping bar used to flat-tow a car behind a motorhome. A tow hook is a recovery point, a forged loop or hook bolted to the frame, used to pull a stuck vehicle out or to tie it down on a flatbed; it is never used to tow a trailer. Using any of them for the wrong job is dangerous: hooks and tie-down loops are not rated for sustained towing loads.
Key Takeaways
- Trailer hitch (US) = tow bar (UK/AU): a frame-mounted receiver or ball for pulling trailers.
- Tow bar (US): the rigid bar that connects a towed car to a motorhome for flat towing.
- Tow hook: a recovery point for extracting a stuck vehicle or securing it on a transport; not for trailers.
- Transport tie-down loops under many cars are not recovery points; check the manual.
- Flat towing requires a vehicle that can be towed with all four wheels down and a base plate kit.
- Each component has a rating; the lowest-rated part in the chain sets the limit.
Three terms that sound similar describe three different pieces of hardware, and the confusion grows because the same word means different things in different countries. Someone searching for a ‘tow bar’ may want a trailer hitch, a motorhome towing setup or a recovery point, and buying the wrong one can mean a failed tow or a torn bumper. This guide defines each item, explains what it is rated for, and covers the main use cases: trailer towing, flat towing behind an RV and vehicle recovery.
The Three Terms Compared
| Term | What it is | Used for | Rated for | Not for |
|---|---|---|---|---|
| Trailer hitch (US) / tow bar (UK, AU, NZ) | Receiver tube or ball mount bolted to the frame | Pulling trailers, bike racks, cargo carriers | Gross trailer weight and tongue weight by class | Recovery pulls with sudden loads |
| Tow bar (US) | A-frame or telescoping bar from the RV hitch to a base plate on the towed car | Flat-towing a vehicle behind a motorhome | Weight of the towed vehicle (typically 5,000–10,000 lb) | Trailers; vehicles not approved for flat towing |
| Tow hook / recovery point | Forged hook or closed loop bolted to the frame or bumper | Pulling a stuck vehicle out; securing it on a flatbed | Short, dynamic recovery loads | Towing a trailer; towing on the road |
| Tie-down loop / transport eye | Thin loop under the car used in shipping | Strapping the car down for transport | Static tie-down forces only | Recovery pulls; towing |
| Screw-in tow eye | Threaded eye stored with the spare, screws into a bumper socket | Light pulls onto a flatbed, short road recovery at low speed | Gentle straight-line pulls | Snatch recoveries; trailer towing |
Trailer Hitch (Tow Bar in the UK and Australia)
A trailer hitch is a steel frame bolted to the vehicle’s chassis with either a fixed ball (common in Europe and Australia, where a tow bar is often a swan-neck or flange-type with a 50 mm ball) or a square receiver tube (standard in North America, 1¼ or 2 inches) that accepts a ball mount. Hitches are rated by class or, in Europe, by maximum towing weight and nose weight, and the vehicle’s own rating caps whatever the hitch allows. Electrical wiring for the trailer lights is separate. Detachable and retractable tow bars are popular in Europe because the ball can be removed when not in use, which also avoids parking-sensor interference.
Tow Bar for Flat Towing (US Meaning)
In the American RV world, a tow bar is the rigid connector that lets a motorhome pull a car with all four wheels on the road. The system has three parts: a base plate bolted to the car’s frame with two attachment points behind the grille, the tow bar itself (usually telescoping and self-aligning, stored folded on the RV’s hitch), and safety cables, wiring and a supplemental braking system that applies the car’s brakes when the RV brakes. Only vehicles the manufacturer approves for flat towing can be towed this way; many automatics cannot, and the owner’s manual states the procedure (transmission in neutral, key position, mileage limits). Jeep Wranglers, some Fords and GM trucks, and certain Subarus and Hondas are common choices. Tow bars are rated from about 5,000 to 10,000 pounds; the car’s weight must be under the rating and within the RV’s hitch and chassis limits.
Tow Hooks and Recovery Points
A tow hook is a forged steel hook or closed loop bolted directly to the frame, front or rear, designed to take the sudden, high loads of pulling a stuck vehicle. Trucks and SUVs with tow packages often have them from the factory; aftermarket bumpers add rated recovery points. They work with a kinetic recovery rope or strap and rated shackles. Two cautions: first, the small looped tabs under many cars are transport tie-downs for shipping and will tear out under a recovery pull; second, hooks are not for towing on the road, because they have no provision for a controlled connection and the load direction changes constantly. The screw-in tow eye supplied with many modern cars is for light, straight-line pulls onto a flatbed at walking speed, nothing more.
Which One Do You Need?
- Towing a trailer, caravan, boat or bike rack: a trailer hitch (tow bar in the UK), rated for your load.
- Taking a car behind a motorhome: a base plate, a flat-tow bar and a braking system, on a vehicle approved for it.
- Off-roading or driving in snow and mud: rated recovery points (tow hooks) front and rear, a kinetic rope and shackles.
- Loading a car onto a flatbed: the screw-in tow eye or factory tie-down points, as the manual directs.
Ratings and the Weakest Link
Every component carries a rating: the hitch class, the ball mount, the ball, the coupler, the safety chains, the tow bar, the base plate, the hook and the shackle. The lowest rating in the chain is the limit, and the vehicle’s own tow rating or GCWR overrides all of them. A Class 3 hitch on a crossover rated to tow 1,500 pounds still tows 1,500 pounds. For recovery, use equipment rated at two to three times the vehicle’s weight, because a kinetic pull multiplies the load.

Frequently Asked Questions
Is a tow bar the same as a trailer hitch?
In the UK, Australia and New Zealand, yes: tow bar is the term for a trailer hitch. In the US, a tow bar usually means the rigid bar used to flat-tow a car behind a motorhome, while the device for pulling a trailer is called a hitch.
Can I tow a trailer with a tow hook?
No. Tow hooks are recovery points for pulling a stuck vehicle or securing it on a flatbed. They are not designed for the sustained, changing loads of towing a trailer on the road.
What is a tow hook for?
Recovering a stuck vehicle with a strap or kinetic rope, and securing a vehicle on a transport. Factory hooks on trucks and SUVs and aftermarket rated recovery points are designed for the sudden loads involved.
Can any car be flat-towed behind an RV?
No. Only vehicles the manufacturer approves for towing with all four wheels down, typically certain Jeeps, trucks, and some manual or specific automatic models. The owner’s manual states whether and how.
Are the loops under my car tow hooks?
Often not. Many small loops are transport tie-downs for shipping and will fail under a recovery pull. Check the owner’s manual for the designated towing eye or recovery points.
Conclusion
A trailer hitch pulls trailers, a flat-tow bar connects a car to a motorhome, and a tow hook gets a stuck vehicle out; in the UK and Australia the first is simply called a tow bar. Each is rated for its own job and none substitutes for another. Decide what you are actually trying to do, check the vehicle manual for approved points and limits, and buy the component built for that task.
