Drivers should not be forced to use mobile apps to pay for parking, the RAC has said, after three-quarters of drivers it surveyed said they had issues with them.
The most common problem was poor phone signal in the car park, followed by the app not recognising the car park the driver was in.
The findings come as the government prepares to expand its National Parking Platform (NPP), which aims to prevent drivers from having to download multiple parking apps.
The RAC welcomed the NPP but said more local authorities and parking companies needed to sign up.
RAC senior policy officer Rod Dennis said parking operators "should offer drivers at least two different ways to pay".
