Why Slopes Are a Problem
When you lift a vehicle on a slope, the weight isn’t sitting evenly on the jack. Part of it is pushing sideways. Every jack has a limit to how much side-load it can take. Go past that limit and the jack buckles or kicks out.
This isn’t about the jack quality. It’s physics.
The higher the vehicle lifts, the more unstable it becomes. A car that’s perfectly stable at ground level can become dangerously unbalanced when raised just a few inches—especially if the ground isn’t level. The jacking point is designed to take weight vertically, not at an angle.
What We Look At
The angle
Some slopes are fine. Some aren’t. We look at the road and make a judgement based on experience. If it looks steep enough that you’d struggle to stand comfortably, it’s probably too steep to lift safely.
A useful test: if water would run down it, so would a car if the jack fails. That’s the mental check we use.
The surface
Tarmac holds well. Loose gravel doesn’t. Wet grass is a problem. If the ground shifts underfoot, it’ll shift under a jack. We also check for camber—roads are often sloped sideways for drainage, which adds another angle to the problem.
Where the car is pointing
Facing downhill is worse than facing uphill. The car wants to roll forward. Lifting a wheel makes that worse. On a downhill slope, the vehicle’s centre of gravity shifts toward the front, so lifting the rear is particularly unstable. On an uphill slope, lifting the front can be just as bad.
What’s underneath
Some cars have plastic sill covers. Some have jacking points that are rusted. Some have been jacked in the wrong place before and the metal is bent. We check before we lift. A jacking point that looks fine from above can be corroded underneath where you can’t see.
The vehicle itself
SUVs and vans are taller and have a higher centre of gravity. They’re more prone to tipping than low saloons. A slope that might be borderline for a Ford Focus could be completely unsafe for a Transit Custom.
What Happens If It’s Not Safe
Sometimes we can move the car to a flatter spot. If the tyre still has some air, we might pump it up and ask you to drive slowly to level ground while we follow. This works more often than people expect—many punctures are slow leaks, not instant deflations.
Sometimes we can’t. If the tyre is completely flat and the slope is too steep, we won’t lift it. We’ll explain why and help you figure out what to do next. This might mean calling recovery or finding someone who can tow you to level ground.
In some cases, we can remove the wheel on the slope but only refit once the car is on flat ground. That means two lifts—one to get the wheel off, then moving the car, then another to put the new wheel on. It’s more work, but it’s safer than trying to do everything in one place.
What Drivers Should Know
If you get a flat on a slope:
- Don’t try to change it yourself. The jack in your boot is smaller and less stable than professional equipment. If we won’t risk our jacks, you shouldn’t risk yours.
- Don’t stand on the downhill side of the car. If it does come off the jack, that’s the direction it will fall.
- If the tyre isn’t completely flat and there’s level ground nearby, you might be able to creep there slowly. Hazards on. 5-10mph. No sudden steering.
- Tell us it’s on a slope when you call. We’ll ask questions about how steep, what surface, which way the car is pointing. That helps us bring the right approach—or tell you honestly if we can’t help.
- Check your handbrake works. Sounds obvious, but we’ve turned up to jobs where the handbrake barely held on flat ground. On a slope, that’s a non-starter.
Why We Don’t Just “Give It a Go”
Some drivers ask why we won’t at least try. The answer is simple: once a car falls off a jack, you can’t undo it. The damage is done—to the car, possibly to the person underneath it, definitely to the rest of your day.
We’ve seen the aftermath of jacks that slipped. Bent suspension arms. Scored brake discs. Punctured fuel lines. Crushed sills. None of those are worth saving twenty minutes.
What We Carry That Helps
Our vans have equipment that makes slope jobs safer when they are possible:
- Wide-base hydraulic jacksthat spread the load better than scissor jacks
- Industrial wheel chocksthat actually bite into tarmac rather than sliding
- Levelling rampsfor some situations (though these have limits)
- Recovery strapsfor when moving the car a short distance is the best option
But even with all that, some slopes are just too steep. Equipment helps, but it doesn’t override physics.
