Flat Towing Safety CablesRequired by Law in Most States
Safety cables are a legal requirement in most U.S. states for flat towing — and
the last line of defense if your tow bar ever disconnects. We carry Blue Ox
and Roadmaster safety cables rated from 7,500 to 10,000 lbs in straight,
EZ-Hook, double-hook, and permanent-mount styles. Find the right cable for your
tow bar below.
Match your cable style to your tow bar and connection type.
🔙
Straight Hook
Standard J-hook or straight hook — the most common style, fits most tow bar safety cable attachment points
🔘
EZ-Hook
Spring-loaded hook for faster, easier connection — popular with full-time RVers who hook up frequently
🔗
Double Hook
Hook on both ends — attaches to both the tow bar and the vehicle, adding a second secure connection point
🔧
Permanent Mount
Bolts directly to the vehicle’s frame — the strongest and most secure cable mounting option available
Blue Ox
Blue Ox safety cables are designed to match their tow bar systems — Class III rated for lighter vehicles, Class IV for heavier setups up to 10,000 lbs.

Roadmaster safety cables come in straight, EZ-Hook, and double-hook styles in 64″ and 76″ lengths — all rated at 8,000 or 10,000 lbs for serious flat towing.
Most U.S. states require safety cables on any flat towed vehicle — and for good
reason. If your tow bar ever disconnects from the motorhome, the safety cables are
what keep the towed vehicle attached and prevent it from separating entirely. They
are the last line of defense in a disconnect situation, and they cost a fraction of
the damage a runaway towed vehicle would cause.
Blue Ox safety cables come in Class III (7,500 lb) and Class IV
(10,000 lb) ratings, with permanent-mount options for the strongest possible
attachment directly to your vehicle’s frame. Roadmaster safety cables
are available in 64″ and 76″ lengths with straight, EZ-Hook, and double-hook
styles — all rated at 8,000 or 10,000 lbs. EZ-Hook cables are popular with
full-time RVers who hook up frequently. Double-hook cables add a second connection
point on each end for maximum security. Orders over $100 ship free to the lower
48 states.

What is the best safety cable for flat towing a car behind a motorhome?
The best safety cable depends on your tow bar rating and how often you hook up.
For most flat towing setups, a Roadmaster EZ-Hook cable in 76″
is the most convenient everyday choice — the spring-loaded hook makes
connection fast and the 76″ length fits most motorhome-to-vehicle configurations.
For maximum security, Blue Ox permanent-mount cables bolt directly
to the vehicle’s frame and are the strongest attachment available. For 10,000 lb
setups, the Roadmaster double-hook 64″ 10K cables are the
top heavy-duty choice. All are in stock at RV Camp Champ with free shipping on
orders over $100.
Are safety cables required by law for flat towing?
Yes — most U.S. states legally require safety cables on any
vehicle being flat towed. The specific requirement varies by state — some
require one cable, others require two — but the safest and most common
practice is to use two safety cables crossed in an X pattern
beneath the tow bar connection. This cross pattern creates a cradle that catches
the tow bar if it disconnects, preventing the coupler from dragging on the road.
Check your state’s towing laws before your next trip, or call us at
877-736-2267 if you have questions.
What is the difference between EZ-Hook and straight hook safety cables?
A straight hook (or J-hook) is a fixed metal hook that slides
onto the cable attachment point and stays in place with tension. A
EZ-Hook has a spring-loaded latch that clicks closed around the
attachment point — it’s faster to connect and disconnect, and less
likely to accidentally come loose. Full-time RVers who hook up their towed vehicle
frequently strongly prefer EZ-Hook cables for the speed and convenience. Both
are equally rated for strength — the difference is purely in ease of use.
What capacity safety cable do I need for my towed vehicle?
Your safety cable capacity should meet or exceed the Gross Vehicle Weight
(GVW) of your towed vehicle. Most cars and small SUVs weigh between
3,000 and 5,000 lbs — a 7,500 lb Class III cable covers
these comfortably. Full-size SUVs, trucks, and heavier vehicles may approach
6,000–8,000 lbs — use a 10,000 lb rated cable for
these setups. When in doubt, go with the higher-rated cable. The weight rating
on your tow bar is also a good reference — your cables should be rated at
least as high as your tow bar.
What length safety cable do I need for flat towing?
Safety cable length depends on the distance between your motorhome’s rear
hitch and the towed vehicle’s frame connection points. Most flat towing
setups use cables between 64″ and 76″ in length.
The 76″ length is the most commonly recommended —
it provides enough slack for turns and clearance without excessive droop.
64″ cables are used on shorter-wheelbase setups or when
the tow bar arms are shorter. If you’re upgrading cables, measure the
distance from the hitch to the safety cable attachment points with your vehicle
connected — or call us at 877-736-2267 for a recommendation.
