The Dangers of Towing with an Engaged Parking Brake
When the emergency brake, often referred to as the parking brake or handbrake, is engaged, it directly applies friction to the wheels of the vehicle. This friction is designed to hold the vehicle stationary. When you attempt to tow a car with this brake on, you are essentially dragging a locked or partially locked wheel against the road surface. This creates immense resistance, putting undue stress on multiple components of both vehicles.
Effects of Towing with the Parking Brake Engaged
The repercussions of towing a car with the parking brake on are multifaceted and often severe. The primary effects stem from the constant friction and strain placed upon the braking system and drivetrain.
Damage to the Braking System
The most immediate and predictable consequence of towing with the parking brake on is the damage inflicted upon the braking system of the towed vehicle.
- Overheating and Failure: The constant friction generates substantial heat. Brake pads, rotors, and calipers are not designed for prolonged, high-friction engagement during motion. This heat can lead to brake fade, where the brakes lose their effectiveness, or even complete brake failure.
- Scoring and Warping of Rotors: The intense heat can cause brake rotors to warp, leading to pulsating braking and eventual failure. The friction can also score the surface of the rotors, requiring replacement.
- Degradation of Brake Pads: Brake pads are designed for intermittent use. Continuous dragging will rapidly wear them down, potentially to the point where metal-on-metal contact occurs, further damaging the rotors.
- Damage to Cables and Actuators: For vehicles with cable-actuated parking brakes, the constant tension can stretch, weaken, or even snap the cables. For electronic parking brakes, the actuator mechanism can be severely stressed and damaged.
Strain on the Drivetrain and Transmission
Beyond the brakes, the drivetrain and transmission of both vehicles are subjected to immense pressure.
- Towing Vehicle Transmission Strain: The towing vehicle’s transmission has to work significantly harder to overcome the resistance of the locked wheel. This can lead to overheating of the transmission fluid, premature wear of gears and clutches, and eventual transmission failure.
- Drivetrain Components: Axles, driveshafts, and differentials in both vehicles are put under extraordinary stress. This can lead to bent axles, damaged U-joints, and stressed differentials, all of which are expensive to repair or replace.
- Tires: The tires on the towed vehicle will experience severe abrasion and potential blowouts due to the constant dragging and friction. This can be dangerous, especially at higher towing speeds.
Damage to the Towing Equipment
The towing apparatus itself is not immune to the excessive forces involved when towing a car with the brake on.
- Strained Towing Hitch and Ball: The hitch on the towing vehicle and the ball mount can be subjected to forces beyond their rated capacity, potentially bending or breaking.
- Damaged Towing Straps or Chains: If straps or chains are used, the constant pull against resistance can cause them to stretch, fray, or even snap, leading to the towed vehicle becoming detached.
Towing Safety Parking Brake Considerations
Prioritizing towing safety parking brake protocols is paramount. The engagement of the parking brake creates a critical safety hazard that must be avoided at all costs.
Loss of Control
A vehicle being towed with its parking brake partially or fully engaged can behave erratically. The uneven resistance can cause the towed vehicle to swerve or pull unpredictably, making it difficult for the towing driver to maintain control. This significantly increases the risk of an accident.
Increased Braking Distance
If the towing vehicle needs to brake suddenly, the added resistance from the towed vehicle’s engaged parking brake will dramatically increase the overall braking distance, potentially leading to a collision.
Reduced Maneuverability
The towed vehicle’s ability to steer and respond to the towing vehicle’s movements will be severely compromised. This makes complex maneuvers, such as turning corners or changing lanes, incredibly risky.
Why People Might Incorrectly Tow with the Emergency Brake On
Several misconceptions or oversights can lead to the dangerous mistake of towing with the parking brake on.
Misunderstanding of the Parking Brake Function
Some individuals might not fully grasp how the parking brake operates. They may believe it only engages a small portion of the braking system or that its effect is negligible when the vehicle is being moved.
Negligence or Rushing
In stressful situations, such as needing to move a disabled vehicle quickly, drivers may overlook checking the parking brake status. The rush to get the job done can override proper safety procedures.
Lack of Experience
New drivers or those with limited towing experience might not be aware of the specific risks associated with an engaged parking brake. They may assume standard towing procedures are sufficient.
Failure to Properly Prepare the Towed Vehicle
Proper preparation is key. This includes ensuring the towed vehicle’s steering wheel is unlocked, the transmission is in neutral (for automatic transmissions) or the clutch is disengaged (for manual transmissions), and crucially, that the parking brake is fully released.
Correct Procedures for Towing a Vehicle
To avoid the pitfalls of towing car engaged handbrake, adhering to correct towing procedures is essential.
H3: Releasing the Parking Brake
The first and most critical step before attempting to tow any vehicle is to ensure the parking brake is completely disengaged.
- Locate the Lever/Pedal: Identify the parking brake lever (usually between the front seats) or pedal (often to the left of the driver’s seat).
- Disengage Fully: Firmly pull up on the lever or press the pedal to release the brake. You should hear or feel a distinct release.
- Confirm Release: Gently try to push the towed vehicle to ensure it rolls freely.
H3: Neutral Gear and Steering Wheel Lock
- Automatic Transmissions: Shift the transmission into “Neutral” (N). This disconnects the engine from the drive wheels.
- Manual Transmissions: Shift the transmission into “Neutral” and fully disengage the clutch.
- Steering Wheel Lock: Ensure the steering wheel is unlocked. Many vehicles lock the steering wheel when the ignition is off. You will need to insert the key and turn it to the “Accessory” or “On” position (without starting the engine) to unlock the steering column. This allows the towed vehicle to follow the towing vehicle’s path.
H3: Securing the Towed Vehicle
Properly securing the towed vehicle is vital for safe towing.
- Towing Method: Choose an appropriate towing method, such as a tow dolly, a car hauler trailer, or flat towing (also known as dinghy towing). Each method has specific requirements.
- Tow Dolly: The front wheels of the towed vehicle are placed on the dolly, and the rear wheels remain on the ground. Ensure the dolly is properly secured to the towing vehicle.
- Car Hauler Trailer: The entire towed vehicle is loaded onto a trailer. This is generally the safest method as all four wheels are off the ground.
- Flat Towing: All four wheels remain on the ground, and the towed vehicle is attached directly to the towing vehicle via a tow bar. This method requires specific equipment and vehicle preparation.
- Chains and Straps: Use safety chains or straps to connect the towed vehicle to the towing vehicle as a secondary measure in case the primary connection fails.
Consequences of Towing with Parking Brake On: A Deeper Dive
The consequences of towing with parking brake on extend beyond immediate damage and can have long-term financial and safety implications.
H4: Financial Repercussions
The cost of repairing damage caused by towing a car with parking brake on can be substantial.
- Brake System Overhaul: Replacing warped rotors, burnt brake pads, and potentially damaged calipers can easily run into hundreds or even thousands of dollars, depending on the vehicle.
- Transmission Repair/Replacement: Transmission damage is notoriously expensive. A rebuild or replacement can cost anywhere from $3,000 to $8,000 or more.
- Drivetrain Component Replacement: Axles, driveshafts, and differential repairs can add several thousand dollars to the repair bill.
- Tire Replacement: Worn or blown tires will require immediate replacement.
H4: Safety Hazards
The most critical consequence is the heightened risk of accidents.
- Loss of Control: As mentioned, the uneven drag can lead to unpredictable movements, putting the towing vehicle and other road users at risk.
- Brake Failure: If the towed vehicle’s brakes fail due to overheating, it can become a runaway vehicle.
- Detachment: If towing equipment fails under the extreme stress, the towed vehicle could detach, causing a dangerous situation on the road.
H4: Legal and Insurance Implications
- Liability: If an accident occurs due to improper towing practices, such as driving with emergency brake on while towing, the responsible party can be held liable for damages and injuries.
- Insurance Claims: Insurance companies may deny claims related to damage caused by negligence or improper towing, especially if it’s evident that the parking brake was engaged.
Identifying if the Emergency Brake is Engaged
It’s crucial to be able to identify if the emergency brake is engaged to prevent towing vehicle with brake applied.
H5: Visual Indicators
- Dashboard Warning Light: Most vehicles have a dashboard warning light that illuminates when the parking brake is engaged. This light is often red and may display the letters “BRAKE” or an exclamation mark inside a circle.
- Lever/Pedal Position: Visually check the position of the parking brake lever or pedal. If it’s in the upward or engaged position, the brake is on.
H5: Auditory and Tactile Clues
- Sound: You might hear a creaking or groaning sound from the rear of the vehicle when attempting to tow with the brake on, especially at low speeds.
- Resistance: A clear tactile indication is the significant resistance you will feel when trying to push or pull the vehicle. It will not roll freely.
Can You Tow A Car With The Emergency Brake On? A Definitive Answer
To reiterate, the answer to “Can you tow a car with the emergency brake on?” is a resounding NO. This is not a grey area; it is a fundamental rule of safe towing. The potential for catastrophic damage and severe accidents far outweighs any perceived convenience or necessity.

Towing a Car with Parking Brake
When you are towing a car with parking brake, you are essentially dragging a friction component against the road. This is akin to dragging a very heavy object with a locked wheel. The resistance is significant, and the heat generated is immense.
Can I Tow A Car With The Brake On?
The answer to “Can I tow a car with the brake on?” is a clear and unequivocal NO. Always ensure all brakes are released before towing.
Towing Car Engaged Handbrake
If you encounter a situation where you believe a car has its towing car engaged handbrake, stop immediately and address the issue. Continuing to tow can escalate the damage and create an unsafe driving environment.
Driving with Emergency Brake On
While this article focuses on towing, it’s worth noting that driving with the emergency brake on, even for short distances, can cause similar damage, albeit to a lesser extent than towing. It leads to accelerated brake wear, potential overheating, and reduced fuel efficiency.
Frequently Asked Questions (FAQ)
Q1: What happens if I accidentally tow a car with the emergency brake on for a short distance?
Even a short distance can cause significant damage. You will likely experience overheating of the brake components. Inspect the brakes immediately after stopping. Check for unusual smells, discolored rotors, or reduced braking performance. It’s wise to have a mechanic inspect the braking system and potentially the transmission afterward.
Q2: Is it safe to tow a car with its transmission in park (P)?
No, it is not safe to tow a car with its transmission in Park. For automatic transmissions, this locks the drive wheels, similar to the parking brake. For manual transmissions, towing in gear can also cause damage to the transmission and drivetrain. Always tow in neutral for automatics and neutral with the clutch disengaged for manuals.
Q3: My parking brake is stuck and won’t release. Can I still tow the car?
If your parking brake is stuck, you must resolve the issue before towing. Attempting to tow with a stuck parking brake is just as dangerous as towing with it intentionally engaged. You might need to have the vehicle towed to a mechanic to free the brake or have it repaired.
Q4: How can I check if the emergency brake is fully released?
After disengaging the parking brake lever or pedal, try pushing the vehicle. If it rolls freely without significant resistance, the brake is likely released. Also, check your dashboard for the warning light; it should be off.
Q5: What is the best way to tow a vehicle?
The safest methods are using a car hauler trailer (where all four wheels are off the ground) or a tow dolly (where the front wheels are lifted). Flat towing can also be safe if the vehicle is equipped for it and all procedures are followed correctly. Never tow a vehicle with its transmission in Park or with the parking brake engaged.
Conclusion
The question, “Can You Tow A Car With The Emergency Brake On?” has a clear and emphatic answer: no. The severe risks to both vehicles, including catastrophic mechanical failures and significant safety hazards, make this practice absolutely unacceptable.
