How To Pull A Car With A Tow Bar – Safely Flat Towing Your Vehicle

Flat towing a vehicle with a tow bar is a practical solution for many situations, from RV travel to vehicle recovery. This comprehensive guide will walk you through the entire process, from understanding your equipment to executing a safe and legal tow, ensuring you have the confidence to hit the road.

Whether you’re an avid RVer looking to bring a smaller vehicle along for adventures or a DIY mechanic needing to transport a project car, the prospect of towing can seem daunting.

However, with the right knowledge and preparation, flat towing a vehicle using a tow bar is a straightforward and efficient method.

This article will demystify the process and provide you with expert, step-by-step instructions on how to pull a car with a tow bar safely and effectively.

Understanding Tow Bars and Flat Towing

A tow bar is a rigid piece of equipment that connects a towed vehicle (often called a “dinghy” when flat towed behind an RV) directly to a tow vehicle, typically a motorhome or a robust truck.

Unlike a car trailer or dolly, the towed vehicle’s four wheels remain on the ground.

This method, known as flat towing, offers convenience and reduces the need for storage space for a trailer.

Types of Tow Bars

There are generally two main types of tow bars you’ll encounter:

• Rigid Tow Bars: These are fixed-length bars, often more economical, but require precise alignment between the vehicles for connection.
• Self-Aligning (Telescoping) Tow Bars: These are more popular, especially for RVers. They feature telescoping arms that allow for easier hook-up, even if the vehicles aren’t perfectly aligned.

Both types typically connect to a base plate installed on the front of the towed vehicle and a receiver hitch on the tow vehicle.

Benefits and Considerations of Flat Towing

Flat towing is often preferred for its ease of use and reduced setup time compared to trailer towing.

It also eliminates the need to maintain a separate trailer or find space to store it.

However, not all vehicles can be flat towed without modification or risk of damage, making careful research essential.

Is Your Vehicle Suitable for Flat Towing?

Before you even consider purchasing a tow bar, the most critical step is to determine if your towed vehicle is “flat towable.”

Improperly flat towing a vehicle can lead to severe transmission damage, drivetrain issues, or even catastrophic failure on the road.

Consult Your Owner’s Manual

The definitive answer for your specific vehicle is always found in its owner’s manual.

Look for sections on “recreational towing,” “dinghy towing,” or “flat towing.”

Many manuals explicitly state whether the vehicle can be flat towed, and if so, outline specific procedures.

Transmission and Drivetrain Compatibility

Manual transmission vehicles are often more straightforward to flat tow, usually by placing the transmission in neutral.

Automatic transmissions are trickier; some can be flat towed, while others require driveshaft disconnects or the removal of fuses.

Four-wheel-drive (4WD) or all-wheel-drive (AWD) vehicles often have transfer cases that can be put into a neutral position, but always verify this.

Ignoring these instructions can lead to expensive repairs.

Weight Ratings and Capacities

Ensure your tow vehicle’s towing capacity exceeds the gross vehicle weight (GVW) of the towed vehicle.

Also, check the tow bar’s weight rating and the receiver hitch’s capacity.

Exceeding any of these ratings is a significant safety hazard and illegal in most places.

Essential Gear for a Safe Tow Bar Setup

Having the right equipment is paramount for a secure and compliant flat towing experience.

Don’t cut corners on these items; your safety and the safety of others depend on it.

The Tow Bar Itself

Choose a tow bar with a weight rating that comfortably exceeds the weight of your towed vehicle.

Consider a reputable brand known for durability and ease of use.

Self-aligning models, while more expensive, significantly simplify the hook-up process.

Base Plate Kit

A custom-fit base plate is crucial. This kit bolts directly to the frame of your towed vehicle.

It provides the secure attachment points for the tow bar.

Installation typically requires some mechanical skill, often involving drilling and working under the vehicle.

If you’re unsure, consider professional installation.

Supplemental Braking System

Most states require a supplemental braking system for the towed vehicle, especially if it exceeds a certain weight (often 1,500 to 2,000 lbs).

These systems apply the brakes on the towed vehicle in sync with the tow vehicle.

Types include proportional systems, which apply brakes with varying force, and surge brakes, which react to the tow vehicle slowing down.

A good braking system significantly improves stopping power and safety, reducing wear on your tow vehicle’s brakes.

Safety Chains or Cables

Two independent safety chains or cables are a non-negotiable requirement.

They act as a backup in case the primary tow bar connection fails.

Cross them underneath the tow bar to form an “X” shape; this helps cradle the tow bar if it detaches and prevents the towed vehicle from swinging wildly.

Towing Lights and Wiring Harness

The towed vehicle’s taillights, brake lights, and turn signals must function in sync with the tow vehicle’s lights.

This requires a wiring harness that connects the tow vehicle’s electrical system to the towed vehicle’s lights.

Some systems use the towed vehicle’s existing bulbs, while others use separate magnetic lights placed on the rear of the towed vehicle.

A working lighting system is critical for visibility and legal compliance.

Step-by-Step Guide: How to Pull a Car with a Tow Bar

Now that you have all the necessary equipment and have confirmed your vehicle’s suitability, let’s go through the process of connecting and preparing your vehicle for towing.

1. Prepare the Tow Vehicle and Towed Vehicle

Position your tow vehicle on level ground, ideally in a straight line with where the towed vehicle will be.

Ensure the towed vehicle is also on a level surface, if possible, and that its parking brake is engaged.

Remove any accessories from the front of the towed vehicle that might interfere with the tow bar, such as bike racks or brush guards.

2. Attach the Tow Bar to the Receiver Hitch

Slide the tow bar’s shank into the receiver hitch of your tow vehicle.

Align the pinholes and insert the hitch pin, securing it with a cotter pin or lock.

Ensure there’s no excessive play once secured.

3. Connect the Tow Bar to the Base Plate

Roll or back the tow vehicle until the tow bar arms are near the base plate attachment points on the towed vehicle.

For self-aligning tow bars, simply get them close; the arms will extend and lock into place as you drive forward slightly.

For rigid tow bars, precise alignment is key.

Insert the pins through the tow bar arms and the base plate brackets, securing them with clips or R-pins.

Double-check that all connections are solid and locked.

4. Attach Safety Chains/Cables

Connect the safety chains or cables from the tow bar or base plate to the tow vehicle’s frame or hitch receiver safety chain loops.

Remember to cross them underneath the tow bar to create that crucial “X” pattern.

Ensure they have enough slack to allow for turns but are not dragging on the ground.

5. Connect Wiring for Lights

Plug the towing light harness into the receptacle on both the tow vehicle and the towed vehicle.

Test all lights: turn signals, brake lights, and running lights.

Have a helper confirm they are working correctly on the towed vehicle.

6. Install Supplemental Braking System

Follow the manufacturer’s instructions for your specific supplemental braking system.

This often involves placing a unit in the footwell of the towed vehicle and connecting it to a breakaway switch on the tow vehicle.

Test the system to ensure it’s functioning as intended.

7. Prepare the Towed Vehicle for Travel

This is where your owner’s manual is critical.

Typically, you will need to:

• Place the transmission in neutral.
• Release the parking brake.
• Turn the ignition key to the “accessory” or “unlocked” position (often one click past “off”) to unlock the steering wheel. Do not leave the engine running.
• In some vehicles, you might need to disconnect the battery to prevent it from draining, or pull specific fuses.
• Ensure all windows are up and doors are locked.

Failing to follow these steps can lead to severe damage to the towed vehicle’s steering or drivetrain.

8. Final Inspection

Before moving, walk around both vehicles.

Verify that all connections are secure: tow bar pins, safety chains, wiring, and braking system.

Check tire pressure on both vehicles and ensure nothing is dragging or loose.

Make sure the towed vehicle’s steering wheel is unlocked and free to turn.

On the Road: Driving Dynamics and Safety Tips

Driving with a towed vehicle is different from driving a single vehicle.

Adjust your habits and remain vigilant to ensure a safe journey.

Adjust Your Driving Style

Increased Stopping Distance: Your combined vehicle weight is significantly higher.

Allow much more distance for braking, especially on inclines or in wet conditions. Wider Turns: The towed vehicle will track inside the tow vehicle’s path.

Make wider turns to prevent cutting corners or hitting curbs. Slower Acceleration: Expect slower acceleration due to the added weight.

Merge onto highways cautiously. Speed Limits: Many states have lower speed limits for vehicles towing trailers or other vehicles. Be aware of and obey these regulations.

Regular Checks During Travel

Pull over periodically (every couple of hours or at fuel stops) to perform a quick visual inspection.

Check the tow bar connections, safety chains, and wiring harness.

Feel the hubs of the towed vehicle’s wheels for excessive heat, which could indicate a bearing problem or an engaged parking brake.

Ensure the towed vehicle’s lights are still functioning.

Dealing with Uphills and Downhills

On long uphills, your tow vehicle’s engine and transmission will work harder.

Monitor temperature gauges and downshift if necessary to prevent overheating.

On downhills, use your tow vehicle’s engine braking (downshifting) to help control speed and reduce reliance on your service brakes, preventing them from overheating and fading.

Emergency Braking and Maneuvers

In an emergency, apply brakes smoothly and firmly.

Avoid sudden, jerky movements of the steering wheel, which can cause the towed vehicle to sway or jackknife.

Practice emergency stops in a safe, open area before a long trip.

Troubleshooting Common Tow Bar Issues

Even with careful preparation, issues can arise. Knowing how to diagnose and address them can save you time and stress.

Swaying or Instability

If the towed vehicle sways excessively, check tire pressure on both vehicles.

Ensure the tow bar is properly connected and that there’s no play in the hitch.

Overloading the towed vehicle or improper weight distribution can also contribute to sway.

Sometimes, worn suspension components on either vehicle can be a factor.

Braking System Malfunctions

If the towed vehicle’s brakes aren’t engaging or are dragging, first check all electrical connections for the braking system.

Ensure the breakaway switch is not accidentally pulled.

Refer to your braking system’s manual for specific diagnostic steps.

If issues persist, it’s best to consult a professional.

Electrical Problems (Lights Not Working)

No lights on the towed vehicle usually points to a wiring issue.

Check the main connection points at the tow vehicle’s hitch and the towed vehicle’s harness.

Inspect fuses in both vehicles, and look for damaged or pinched wires.

Corrosion in connectors can also be a culprit; clean them with electrical contact cleaner.

Legal Considerations and Road Regulations

Towing laws vary significantly by state and even country.

Ignorance of the law is not an excuse, and violations can result in fines, accidents, or even legal liability.

Licensing and Endorsements

For most recreational towing with a tow bar, a standard driver’s license is sufficient.

However, if the combined gross vehicle weight rating (GVWR) of your tow vehicle and towed vehicle exceeds a certain threshold (e.g., 26,000 lbs in the U.S.), you might need a commercial driver’s license (CDL) or a special endorsement.

Always check the Department of Motor Vehicles (DMV) regulations for your state and any states you plan to travel through.

Breakaway Systems and Safety Chains

Most jurisdictions mandate safety chains and, for heavier towed vehicles, a breakaway braking system.

A breakaway system automatically applies the towed vehicle’s brakes if it separates from the tow vehicle.

Ensure your setup meets these requirements.

Visibility and Mirrors

You must have an unobstructed view of the road behind you.

If your towed vehicle obstructs your standard rearview mirrors, you’ll need to install extended or auxiliary towing mirrors.

This is often a legal requirement and a critical safety measure.

Crossing International Borders

If you plan to tow internationally (e.g., into Canada or Mexico), research their specific towing regulations and required documentation (e.g., proof of insurance for the towed vehicle).

Some countries have very strict rules regarding vehicle modifications or towing setups.
