Yes, you can drive a car with power steering failure, but it is not safe and should only be done with extreme caution and for a very short distance, such as to move the car off a busy road or to a nearby repair shop. The vehicle will be difficult to control, especially at low speeds, requiring significantly more physical strength to turn the steering wheel.
Power steering uses hydraulic or electric assistance to reduce the effort needed to turn the wheels. When this system fails, you lose that assistance. The steering becomes extremely heavy, making maneuvers like parking, navigating tight corners, or making emergency evasive actions dangerously slow and physically demanding.
The required steering force increases dramatically at lower speeds. For a typical mid-size sedan, the force needed to turn the wheel can be compared as follows:
| Steering Scenario | With Functional Power Steering | With Power Steering Failure |
|---|
| Parking Lot Maneuver | 2-5 lbs of force (very easy) | 20-30 lbs of force (very difficult) |
| Low-Speed Turn (15 mph) | 5-8 lbs of force (easy) | 15-25 lbs of force (hard) |
| Highway Driving (55 mph) | 3-6 lbs of force (light effort) | 8-12 lbs of force (manageable but heavy) |
If you must move the car, reduce your speed significantly. Plan your turns well in advance and avoid sharp steering inputs. Be aware that your ability to react quickly to hazards is severely compromised. The safest course of action is to have the car towed to a repair facility. Driving with a failed power steering pump can also damage other components if it's a hydraulic system, leading to a more expensive repair.
