Yes you can. To let us and the drivers know you are a wheelchair user, tap the Account icon at the top left of the app, scroll down to Options and tap again. From there, you can slide the Wheelchair Accessible option to ‘On’.
All black cabs are wheelchair accessible, but some drivers have been exempted by TFL. This is because they are not able to fit the wheelchair ramp or help a wheelchair user board due to health reasons. By setting the Wheelchair Accessible option to ‘On’, we’ll ensure you get a driver who can help.
