Moving to a new home across state lines is a massive undertaking, especially when you have an extra vehicle to move. You might be staring at your driveway wondering if you should drive it, ship it, or hook it up to a trailer yourself.
Learning how to tow a car to another state doesn’t have to be a logistical headache if you have the right equipment and a solid plan. This guide will walk you through the most reliable methods, safety protocols, and technical steps to ensure your vehicle arrives at its destination without a scratch.
We will cover everything from choosing between a tow dolly and a flatbed trailer to understanding the legal requirements of different states. Whether you are hauling a vintage project car or your daily driver, these expert insights will help you tow with confidence.
Choosing the Best Method for Long-Distance Vehicle Transport
Before you hook up a hitch, you need to decide which method fits your vehicle and your tow rig. Not every car can be towed the same way, and choosing the wrong method can lead to transmission damage or dangerous handling on the highway.
Flatbed trailers are the gold standard for long-distance hauls because they keep all four wheels of the towed vehicle off the ground. This is the safest option for all-wheel drive (AWD) and four-wheel drive (4WD) vehicles that cannot be towed with two wheels down.
A tow dolly is a more affordable, lightweight alternative that lifts only the front wheels off the pavement. This works well for front-wheel drive (FWD) cars, but it is not recommended for rear-wheel drive (RWD) vehicles unless you disconnect the driveshaft to prevent heat buildup in the transmission.
Flat Towing or “Dinghy” Towing
Flat towing involves pulling the car with all four wheels on the ground using a tow bar. This is common for RV owners hauling a “toad” or “dinghy” vehicle, but it requires specific modifications to the towed car.
You must install a base plate on the towed vehicle and often a transmission lube pump if the car isn’t designed for flat towing. Always check your owner’s manual under “recreational towing” to see if your car is compatible with this method.
Using a Car Carrier Trailer
A full car carrier or flatbed trailer is the most versatile choice for DIYers. It provides the most stability and prevents wear and tear on the towed vehicle’s tires, suspension, and drivetrain during the long journey.
When you are planning how to tow a car to another state, using a trailer also allows you to back up more easily than a tow dolly. If you encounter a dead-end or a tight gas station, having the ability to reverse is a massive advantage.
Understanding Weight Limits and Towing Capacity
Safety starts with math, and you must ensure your tow vehicle can handle the load. Exceeding your Gross Combined Weight Rating (GCWR) is a recipe for brake failure and engine overheating on steep mountain passes.
The GCWR is the maximum allowable weight of the tow vehicle, the trailer, the towed car, and all passengers and cargo combined. You can find this number on the driver’s side door jamb sticker or in your vehicle’s manual.
Don’t forget to account for the tongue weight, which is the downward pressure the trailer coupler exerts on the hitch ball. Ideally, the tongue weight should be between 10% and 15% of the total loaded trailer weight for stable tracking.
Hitch Classes and Ratings
Your hitch receiver must be rated for the load you are pulling. A Class III hitch is common for mid-sized SUVs, but for a heavy car and trailer combo, you likely need a Class IV or Class V hitch.
Check the rating stamped on the hitch itself to ensure it meets or exceeds the weight of your trailer and car. Using an undersized hitch can lead to structural failure, which is a catastrophic scenario at highway speeds.
Brake Controllers and Safety Chains
Most states require trailers over a certain weight (often 3,000 lbs) to have their own braking system. You will need an electronic brake controller installed in your tow vehicle to sync the trailer brakes with your foot pedal.
Safety chains are your last line of defense if the coupler fails. Always cross the chains in an “X” pattern under the trailer tongue to create a cradle that will catch the tongue before it hits the pavement.
Step-by-Step Guide on how to tow a car to another state
Once you have selected your equipment and verified your weights, it is time to get the vehicle loaded and secured. Follow these steps carefully to ensure a stable and legal setup for your interstate journey.
Start by attaching the trailer to the tow vehicle while both are on level ground. Ensure the hitch ball is the correct size (usually 2-inch or 2 5/16-inch) and that the locking pin is securely engaged through the coupler handle.
Slowly drive the car onto the trailer or dolly, centering the weight over the axles. If you are using a flatbed trailer, position the car so the front is slightly forward of the trailer axles to maintain proper tongue weight.
Secure the vehicle using heavy-duty ratchet straps or chains rated for the vehicle’s weight. Attach the straps to the vehicle’s frame or “T-slots,” avoiding brake lines, fuel lines, or sensitive suspension components that could bend.
Connect the trailer wiring harness and test all lights, including turn signals, brake lights, and running lights. Many people wonder about the legalities of how to tow a car to another state, and having functioning lights is the number one way to avoid being pulled over.
Before you hit the highway, perform a “tug test” by manually engaging the trailer brakes with the controller while moving slowly. This confirms the connection is solid and the brakes are responding correctly to your inputs.
Essential Safety Checks for Long-Distance Hauling
A cross-country trip puts extreme stress on both vehicles. You should perform a thorough inspection every time you stop for fuel or a rest break to catch potential issues before they become roadside emergencies.
Check the tire pressure on all tires, including the trailer and the towed vehicle. Trailer tires are prone to heat-related blowouts if they are under-inflated, so keep them at the maximum PSI listed on the sidewall.
Feel the wheel hubs on the trailer after an hour of driving. If a hub feels excessively hot to the touch, you may have a failing wheel bearing or a dragging brake that needs immediate attention.
Securing Loose Items
If you are packing the towed car with boxes to save space, ensure they are secured and do not obstruct the driver’s view. However, it is usually better to keep the towed car empty to avoid exceeding the trailer’s weight capacity.
Remove any loose exterior parts, such as magnetic signs, bike racks, or loose trim pieces. The high-speed wind resistance on the highway can turn these items into dangerous projectiles for the drivers behind you.
Managing Sway and Stability
Trailer sway is a terrifying experience where the trailer begins to fish-tail behind the tow vehicle. If this happens, do not slam on the brakes; instead, manually apply the trailer brakes only using the controller to straighten the rig.
To prevent sway, ensure your load is balanced correctly with more weight toward the front of the trailer. If you frequently tow heavy loads, consider investing in a weight distribution hitch with built-in sway control.
Navigating Legal Requirements and State Laws
When you are figuring out how to tow a car to another state, you must realize that laws change the moment you cross the border. What is legal in Texas might result in a citation in California or New York.
Some states require specific types of mirrors if your trailer obstructs your rear view. Extended side-view mirrors are a smart investment for any long-distance tow, as they significantly reduce your blind spots.
Maximum speed limits for towing vehicles are often lower than the posted limit for passenger cars. In states like California, the towing speed limit is 55 mph regardless of the highway’s standard limit; always watch for towing-specific signage.
Registration and Documentation
Ensure both the tow vehicle and the trailer have current registration and insurance. If you are renting a trailer, keep the rental agreement in the glove box, as law enforcement may ask to see it during a routine stop.
If the towed vehicle is not currently registered, you may need a temporary transit permit from your DMV. This allows you to legally move the vehicle through different jurisdictions without permanent plates.
Toll Roads and Height Clearances
Towing a trailer usually increases your toll rate because of the extra axles. Keep some cash or a multi-state transponder handy to avoid hefty fines from automated tolling systems.
Be mindful of your total height, especially if you are towing a tall SUV or truck on a high-deck trailer. Use a GPS app designed for truckers that allows you to input your dimensions to avoid low-clearance bridges or overpasses.
Driving Techniques for Heavy Loads
Driving with a loaded trailer requires a different mindset than driving a standard car. You need more time to accelerate, more space to stop, and a much wider turning radius to clear curbs and obstacles.
Practice “defensive towing” by maintaining a following distance of at least double what you would normally keep. This gives you a buffer to slow down gradually, preventing the trailer from pushing the tow vehicle during hard braking.
When descending long grades, use engine braking by shifting to a lower gear rather than riding your brakes. Constant braking on a downhill stretch can lead to brake fade, where the pads overheat and lose their stopping power.
Fueling and Maneuvering
Planning your fuel stops is critical. Look for “truck-friendly” gas stations or travel centers like Love’s or Pilot, which offer wide pull-through lanes designed for large rigs and trailers.
Avoid backing up whenever possible, but if you must, remember to move the bottom of the steering wheel in the direction you want the trailer to go. Small, slow movements are key to preventing the trailer from jackknifing.
Weather Considerations
High winds can be particularly dangerous when towing a car to another state. If you experience strong crosswinds, slow down and keep a firm grip on the wheel, as the large surface area of the trailer acts like a sail.
In heavy rain, be extra cautious of hydroplaning. If the tow vehicle loses traction, the trailer can easily push you into a spin. If conditions become severe, the safest move is to pull over and wait it out.
Frequently Asked Questions About How to Tow a Car to Another State
Is it cheaper to tow a car myself or hire a professional?
Towing the car yourself is usually cheaper if you already own a capable tow vehicle and can rent a trailer. However, once you factor in fuel costs, trailer rental fees, and the value of your time, hiring a professional auto transport company may be competitive for very long distances.
Can I tow an automatic transmission car with all four wheels down?
Most modern automatic vehicles cannot be flat-towed without damaging the transmission because the internal pump only works when the engine is running. Always consult your owner’s manual or use a trailer to be safe.
Do I need a special license to tow a car across state lines?
For most personal vehicles and trailers, a standard driver’s license is sufficient. However, if your Gross Vehicle Weight Rating (GVWR) exceeds 26,000 lbs, you may technically need a commercial driver’s license (CDL), though this is rare for standard car towing.
How do I prevent my car from being damaged by road debris?
Using a car bra or a specialized vehicle cover can protect the front of the towed car from rock chips. If you are using an open trailer, installing “mud flaps” on the tow vehicle’s rear wheels will also significantly reduce the amount of debris kicked up onto the car.
Should I leave the car in gear or park while it is on the trailer?
You should put the towed car in “Park” (for automatics) or in gear (for manuals) and engage the parking brake. However, the primary holding force should always come from the ratchet straps or chains, not the vehicle’s transmission or brakes.
Summary of Key Takeaways
Knowing how to tow a car to another state is a valuable skill for any DIY mechanic or traveler. By selecting the right equipment, respecting weight limits, and practicing safe driving habits, you can save money and ensure your vehicle arrives safely.
Always prioritize safety over speed. Take the time to double-check your connections at every stop, stay within your tow vehicle’s limits, and keep a close eye on the weather and road conditions ahead.
With the right preparation and a bit of patience, your cross-country haul will be a success. Stay safe, keep your eyes on the road, and enjoy the journey to your new destination!
