Do I Need a Tow? 7 Signs Your Car Should Not Be Driven
Something is wrong with your car. Maybe the engine light just came on, maybe there is smoke coming from under the hood, maybe the steering feels strange, or maybe the car simply will not start. The question every Oakville and GTA driver asks in that moment is the same: can I still drive this, or do I need to call tow truck services? Getting the answer wrong in either direction costs you money. Drive a car that should be towed and you risk turning a $300 repair into a $3,000 engine replacement or, worse, causing an accident that puts people at risk. Call a tow truck for something that only needs a quick roadside fix and you spend money unnecessarily. This guide gives you a clear, practical framework for making that decision. We cover the 7 definitive signs that mean your car needs vehicle towing rather than a drive to the mechanic, situations where you can safely drive, what to do while waiting for the tow, and answers to the questions drivers ask most about when to call for a towing service.

Quick Answer
When should you call tow truck services instead of driving? If your car has any of these 7 signs, do not drive it: the temperature gauge is in the red zone, you see fluid pooling under the vehicle, the brakes feel spongy or are grinding metal-on-metal, the engine stalls repeatedly and will not stay running, there is smoke or steam from the engine bay, a tire is flat or visibly damaged, or the car was just in a collision. Any one of these makes driving unsafe and risks further mechanical damage.

The 7 Signs You Need a Tow, Not a Drive
Each of these signs means your vehicle is unsafe to drive, is at risk of further mechanical damage, or both. If you see any one of them, the safest and cheapest decision is to call a tow truck rather than attempt to drive to the shop.
Engine Temperature Is in the Red Zone
What is happening: The engine is overheating. Causes include a coolant leak, failed water pump, broken thermostat, radiator blockage, or a blown head gasket. The temperature gauge is at or past the red line, or the engine temperature warning light is illuminated.
Why you should not drive: An overheating engine can warp the cylinder head, crack the engine block, blow the head gasket, or seize the pistons within minutes. Every kilometre you drive past the red zone increases the damage exponentially. What starts as a $200 thermostat replacement becomes a $4,000 to $8,000 engine rebuild if you keep driving.
What to do: Pull over immediately, turn off the engine, and do not open the radiator cap (it is under extreme pressure). Call for vehicle towing to your mechanic.
Fluid Is Pooling Under Your Vehicle
What is happening: A significant fluid leak is draining one of your vehicle’s essential systems. The colour tells you what is leaking: bright green or orange is coolant, red or brown is transmission fluid, dark brown or black is engine oil, clear or light yellow is brake fluid, and pink is power steering fluid.
Why you should not drive: Running any system without adequate fluid causes internal damage in minutes. A coolant leak leads to overheating. An oil leak starves the engine of lubrication. A brake fluid leak means you may have no braking power. A transmission fluid leak can destroy the transmission within a short drive. A small drip can be monitored, but a puddle means something has failed.
What to do: Do not start the engine. Note the fluid colour and location for your mechanic. Call for a tow to your repair shop.
Brakes Feel Spongy, Grinding, or Unresponsive
What is happening: The brake pedal sinks to the floor, feels soft and spongy, or you hear metal-on-metal grinding when you press it. This indicates air in the brake lines, a brake fluid leak, completely worn brake pads grinding into the rotors, or a failing brake booster.
Why you should not drive: This is a direct safety hazard. If your brakes are compromised, you may not be able to stop the vehicle, especially in an emergency. Driving with brake failure puts you, your passengers, and every other person on the road at risk. There is no grey area here.
What to do: Do not move the vehicle. Call a tow truck immediately. Tell the towing company about the brake issue so they use a flatbed rather than wheel-lift, as loading a car with no brakes requires flatbed and winch.
The Engine Stalls Repeatedly or Will Not Stay Running
What is happening: The engine starts but dies within seconds, or it runs for a few minutes then stalls without warning. It may restart and stall again. Causes include fuel pump failure, clogged fuel filter, failing ignition system, sensor malfunction, or a major electrical fault.
Why you should not drive: A stalling engine means losing power steering, power brakes, and engine power simultaneously while driving. Stalling on the QEW or Highway 403 at highway speed is extremely dangerous because you lose the ability to accelerate, steer easily, and brake effectively all at once. Other drivers behind you will not expect you to suddenly decelerate.
What to do: If the car stalls once and restarts, drive to the nearest safe spot and stop. If it stalls more than once, do not attempt to drive further. Call for a tow.
Smoke or Steam Is Coming from Under the Hood
What is happening: White steam usually means a coolant leak hitting a hot engine component. Grey or blue smoke indicates oil burning where it should not be, such as a leaking valve cover gasket or failed piston rings. Black smoke from the exhaust means the engine is running extremely rich, burning too much fuel. Any of these indicate a system that is actively failing.
Why you should not drive: Smoke means something is burning or leaking onto hot components. At best, you are causing progressive damage with every minute the engine runs. At worst, you are looking at a fire risk, especially if oil is dripping onto the exhaust manifold. Engine fires happen faster than most people expect.
What to do: Pull over safely and turn off the engine immediately. Pop the hood latch but do not fully open the hood if you see heavy smoke, as fresh air can feed a fire. Call for towing service to a mechanic.
A Tire Is Flat, Shredded, or Visibly Damaged
What is happening: A tire is completely flat, has separated tread, has sidewall bulging or cracking, or has been punctured by a large object. You may have hit a pothole on Trafalgar Road, run over construction debris on the QEW, or discovered the flat in a parking lot.
Why you should not drive: Driving on a flat tire even for one kilometre destroys the tire beyond repair and can damage the wheel rim, which costs $200 to $800 to replace. A severely damaged tire can blow out completely at speed, causing loss of control. If the sidewall is damaged, the tire cannot be safely repaired at all.
What to do: If you have a spare, call for a tire change or swap it yourself. If you have no spare or the damage is too severe, call for a tow to a tire shop.
Your Car Was Just in a Collision
What is happening: Your vehicle has been in a crash, even a seemingly minor one. The bumper is crumpled, a headlight is broken, the hood is misaligned, or airbags have deployed. The car may look driveable but there could be hidden damage to the frame, suspension, steering components, or safety systems.
Why you should not drive: A collision can bend structural components that you cannot see from the outside. The steering rack may be slightly bent, a tie rod may be cracked, the radiator support may be pushed into the cooling system, or a wheel may be out of alignment. Driving with hidden collision damage risks a second, more serious incident. If airbags deployed, the vehicle must be professionally inspected before it is driven again.
What to do: Exchange information with the other driver, document the scene, and call for accident towing to the collision reporting centre or your body shop.

A $150 tow is always cheaper than the damage caused by driving a car that should not be on the road.
When Your Car Is Probably Safe to Drive to the Shop
Not every car problem requires a tow. Some issues are concerning but do not make the vehicle unsafe to drive a short distance to your mechanic. Here are situations where driving is generally acceptable:
The general rule is: if the issue affects the engine, brakes, steering, or drivetrain, call tow truck services immediately. If the issue affects comfort, cosmetics, or non-critical electrical systems, you can usually drive to the shop.

What to Do While Waiting for the Tow Truck
Once you have decided to call a tow truck, the waiting period matters for your safety. Here is how to stay safe until the truck arrives:
Move to Safety
If you are on a highway, stay inside your vehicle with your seatbelt on and hazard lights activated. If you are on a city street, pull as far right as possible or into a parking lot. Turn on hazards regardless of location. If the vehicle is smoking, move away from it to a safe distance.
Share Your Exact Location
When you call for a tow, give the dispatcher your precise location: GPS pin, street address, highway direction and nearest exit, or closest intersection. The more specific you are, the faster the truck finds you. Drop a pin on your phone’s map app and share it if possible.
Know Where You Want to Go
The tow driver needs a destination. Have your mechanic’s address ready, or ask the dispatcher for advice on the nearest repair shop. Under Ontario’s TSSEA, you choose where your vehicle goes. Do not let anyone redirect your car to a shop you did not request.
Gather Your Documents
Have your driver’s licence, vehicle registration, and insurance card ready. The tow driver will need your signature on the consent and estimate forms as required by Ontario’s TSSEA legislation. Having documents ready saves time on arrival.
The Real Cost of Driving a Car That Needs a Tow
Many drivers try to save money by driving to the shop instead of calling for vehicle towing. Here is what that gamble actually costs when it goes wrong:
The math is clear: a tow almost always costs $80 to $200. The additional damage from driving a compromised vehicle can cost 10 to 40 times that amount. For detailed pricing on all towing services, see our 2026 Towing Cost Guide.
What to Expect When You Call a Tow Truck
If you have never had to call tow truck services for a car pickup before, the process is straightforward. Here is what happens when you call us at (289) 430-5168:
1. Tell the dispatcher your location, vehicle, and problem.
Be specific: street address or highway and direction, make/model/colour, and what symptom you are experiencing. The dispatcher uses this to select the right truck and equipment.

Before the truck is dispatched, you get an estimated cost and arrival time. No surprises. This is required under Ontario’s TSSEA.
3. The tow truck arrives and loads your vehicle.
The driver assesses the situation, confirms the vehicle condition, and loads it using the appropriate method: flatbed for AWD, luxury, or damaged vehicles; wheel-lift for standard front-wheel-drive cars.
4. Your vehicle is delivered to your chosen destination.
You decide where the car goes: your mechanic, a body shop, your home, or the collision reporting centre if applicable. You receive an itemized invoice on delivery. View our Why Choose Us page or browse our tow truck fleet for details.
Frequently Asked Questions About When to Call a Tow Truck
My check engine light is flashing. Should I call a tow truck?
Yes. A flashing check engine light indicates an active engine misfire, which can damage the catalytic converter within minutes of continued driving. Pull over safely and call for a tow. A steady check engine light is different. It indicates a stored fault that needs diagnosis but is not immediately dangerous.
Can I drive my car a short distance if it is overheating?
No. Even a short drive while overheating can cause permanent engine damage. The cylinders, head gasket, and engine block are all at risk the moment the temperature gauge enters the red zone. Turn off the engine immediately and call for a tow.
My car makes a grinding noise but still drives. Do I need a tow?
It depends on where the noise comes from. Grinding from the brakes means metal-on-metal contact, which requires immediate towing. Grinding from the engine or transmission also warrants a tow. A grinding or humming from a wheel bearing may allow a very short drive at low speed, but get it checked immediately as a failing bearing can seize and lock the wheel.
How much does it cost to call a tow truck in Oakville?
A local tow within Oakville or Burlington typically costs $100 to $200. Roadside services like battery boosts, tire changes, and fuel delivery are even less. You always receive an estimate before dispatch so there are no surprises.
Should I call 911 or a tow truck for a breakdown?
Call 911 only if there is immediate danger: a collision with injuries, a vehicle fire, or a breakdown in a dangerous location where you cannot move to safety. For standard breakdowns, mechanical failures, and flat tires, call a tow truck directly. We dispatch faster than 911-routed roadside services because there is no middleman.
Can I call a tow truck if the car is in my driveway?
Yes. Tow trucks regularly pick up vehicles from driveways, parking lots, garages, and private property. If your car will not start or has a problem that makes it unsafe to drive even a short distance, a tow from your driveway to the shop is a routine call. Our winch service can even pull a car out of a tight garage if needed.
My car is making a weird noise but everything else seems fine. Tow or drive?
If the noise is not accompanied by any of the 7 signs above, it is usually safe to drive a short distance at low speed to a mechanic. However, if the noise suddenly gets louder, or if you notice any vibration, loss of power, or dashboard warning lights, pull over and reassess. When in doubt, a tow is the safer bet.
Does my insurance cover a tow truck call?
Many auto insurance policies in Ontario include roadside assistance and towing coverage. Check your policy details or call your insurer. Even if covered, calling us directly at (289) 430-5168 is usually faster because there is no third-party dispatcher adding delay. You can submit the invoice to your insurer for reimbursement.
Can an electric vehicle be towed normally?
No. Electric vehicles must be towed on a flatbed with all four wheels off the ground. Wheel-lift towing can damage the electric drivetrain. Our EV towing service is equipped to safely handle Tesla, Rivian, BMW i-Series, Hyundai, and all other electric and hybrid vehicles.
How long does it take for a tow truck to arrive?
In Oakville and the GTA, typical arrival time is 15 to 30 minutes. Highway calls are prioritized for safety. During winter storms or high-demand periods, wait times may extend to 45 minutes or longer. We provide an ETA on every call before dispatching. View our full service area and visit our FAQ page for more details.
When in Doubt, Tow It Out.
A tow costs $100 to $200. Driving a damaged car costs thousands. The math always works in your favour.
