Quick answer: If the brace is on your left ankle and you drive an automatic, you are almost certainly fine. If it is on your right ankle, be careful: a driving simulator study found every ankle brace tested slowed how fast people moved their foot to the brake. It is not specifically illegal in the US or UK, but you are still required to be in proper control of the vehicle. The practical answer is to take the brace off to drive when you safely can, which is easy with a brace like the Solehush MotionLock ankle brace because the lock-wrap strap comes off in seconds.

What the research actually found
This is one of the few ankle brace questions with a direct study behind it, so we will use it rather than guess. Researchers in the Journal of Rehabilitation Medicine put 30 healthy volunteers in a simulated car cabin and tested four common ankle braces: the Kallassy, CaligaLoc, Air-Stirrup and ASO.
The results are worth reading honestly, because they are not flattering to the product category we sell in:
- All four braces significantly increased foot transfer time, which is how long it takes to get your foot off the accelerator and onto the brake.
- Reaction time was significantly prolonged with every brace except the Kallassy.
- Brake force was not significantly impaired. Once people got to the pedal, they could press it hard enough.
- Overall, the authors state that depending on the brace, a stopping distance increase of more than 1 metre at 100 km/h can be expected.
One metre is not catastrophic, but it is not nothing either, and it is the difference between stopping behind the car in front and touching it. Two caveats in both directions: those were rigid and semi-rigid braces rather than thin knit sleeves, and MotionLock was not among them, so we cannot claim our brace performs better. We can only say the study did not test it. The safe assumption is that anything strapped to your right foot adds some delay.
Left ankle or right ankle? It changes the answer completely
| Situation | Realistic answer |
|---|---|
| Left ankle, automatic transmission | Your left foot does nothing. Generally fine. |
| Left ankle, manual transmission | You still need the clutch. Test it stationary first. |
| Right ankle, automatic | This is the risky one. Both pedals are your right foot. |
| Right ankle, manual | Same risk, plus more pedal movement overall. |
| Either ankle, a walking boot or cast | Do not drive in it. See the section below. |
Most people asking this question have hurt one ankle and have not stopped to think about which pedals that foot is responsible for. If you drive an automatic in a right-hand-drive country, your left foot is idle and a left ankle brace changes nothing about your driving. That is the easy case.
Is it illegal to drive with an ankle brace?
There is no law in the US or the UK that names ankle braces and bans them. What exists instead is a general duty to be in proper control of the vehicle, and rules about driving with a medical condition that affects your driving. In the UK the DVLA guidance on driving with medical conditions is the reference point. In the US, requirements vary by state.
Two practical things follow from that. First, if an officer decides your injury made you drive erratically, the citation will be about control or careless driving, not about the brace. Second, and more expensive, an insurer can dispute a claim if it believes you were not able to operate the vehicle properly. That is the risk worth taking seriously, and it is a conversation to have with your insurer rather than with a product page.
What about a walking boot or a cast?
Different object, different answer, and the answer is clearer: do not drive in one. A boot immobilises the ankle by design, it is bulky enough that the foot can catch between the pedals, and it is built for weight-bearing rather than the fine control that pedal work needs. If you are unsure which device you should be in at this stage of a recovery, we go through it in ankle brace vs walking boot.
If you do need to drive
- Take the brace off for the drive if your ankle can bear that safely, and put it back on when you park. This is the single most effective option.
- Test it stationary first. Engine off, move your foot between the pedals ten times. If it snags or feels slow, that is your answer.
- Check the tension. A brace cranked tight for sport restricts far more than one set for walking, and fit changes how much movement you lose. Our guide on how tight should an ankle brace be covers the checks.
- Consider a lighter option for the car. A compression sleeve restricts much less than a strapped brace, and for a drive that is the point. It will not protect against a roll, so it is a trade. We compare them in ankle brace vs compression sleeve.
- Wear a normal shoe. Thick soles blunt pedal feel on top of whatever the brace is already costing you.
Where MotionLock fits
We are not going to tell you a brace makes you a safer driver, because that is not what the evidence says. What MotionLock is genuinely good for here is how quickly it comes on and off. The adjustable lock-wrap strap means you are not unlacing a boot or unpicking tape in a car park, so removing it for a drive and putting it back on at the other end is a ten second job rather than a reason to leave it on.
The rest is the same as always: a hexagon grip zone over the outer ankle bone where lateral sprains happen, an open heel so it does not bunch, and a thin knit that fits inside sneakers, court shoes and work boots.

If you are working out your overall wear pattern rather than just the driving question, we cover that in how long should you wear an ankle brace each day, and the night-time version of the same question in can you sleep with an ankle brace on.
Frequently asked questions
Can you drive with an ankle brace on your right foot?
You can, but it is the riskiest version of this question. A driving simulator study found every ankle brace tested increased foot transfer time to the brake, with more than 1 metre of extra stopping distance at 100 km/h depending on the brace. If you can safely take it off for the drive, do that instead.
Is it illegal to drive wearing an ankle brace?
No law in the US or UK specifically bans ankle braces. You are still required to be in proper control of the vehicle, and an insurer can dispute a claim if it believes you could not operate the car properly. Check with your insurer and your doctor rather than assuming.
Does an ankle brace affect braking distance?
Yes, modestly. The Journal of Rehabilitation Medicine study reported that depending on the brace type, more than 1 metre of extra stopping distance at 100 km/h can be expected. Brake force itself was not significantly impaired, so the delay is in getting to the pedal rather than pressing it.
Can I drive with a brace on my left ankle?
In an automatic, your left foot is not operating the pedals, so a left ankle brace generally does not affect your driving. In a manual you still need the clutch, so test the movement while stationary before you set off.
General information, not medical or legal advice. Whether you are fit to drive after an ankle injury is a decision for your doctor, and cover is a question for your insurer. If your ankle is painful to weight-bear, keeps giving way or stays swollen, get it assessed before you drive. Results vary.
