Quick Answer: Stop driving immediately if you see red (transmission), green (coolant), or black oil pooling rapidly. Clear or light-colored fluid might be condensation and usually safe. Dark, thick leaks or large puddles mean call for emergency tow right now.
What To Do
- Pull over safely and turn off the engine immediately
- Check the fluid color and amount by looking under the car from a safe distance
- Red fluid: Transmission fluid. Do not drive. Call tow truck.
- Green/orange fluid: Coolant. Engine will overheat. Call tow truck.
- Dark oil: Major leak means no lubrication. Call tow truck.
- Clear water: Likely AC condensation. Safe to drive short distances.
- Take a photo of the leak and fluid color for the mechanic
- Check fluid levels on dipsticks if you can do so safely
- Never drive if you see steam, smell burning, or hear unusual noises

Immediate Safety Checks
Before calling for tow, verify these danger signs:
- Temperature gauge rising: Engine overheating imminent
- Oil pressure light on: Engine damage happening now
- Large puddle forming: Major system failure
- Sweet smell: Coolant leak, toxic and flammable
- Burning smell: Fluid hitting hot components
What It Might Cost
Emergency tow during business hours: $75-150 for first 5 miles After hours or weekends: $100-200 Major repairs if you keep driving: $1,500-5,000+
The tow cost is nothing compared to engine replacement.
