Error 15 after selecting ‘Start now’

Problem

When you select the ‘Start now’ button, you see an Error 15 message and are told your request has been blocked by the security rules.

The message will tell you:

  • your internet protocol (IP) address (a series of numbers)
  • your proxy IP address (a series of numbers)
  • an incident ID number

This can happen when you:

  • search the service too often
  • access the service from outside the UK
  • access the service using a virtual private network (VPN)
  • use third-party booking sites or apps to access the service to search for appointments

Solution

You can:

  • try again later
  • avoid doing a large number of searches in a short time
  • access the services directly through GOV.UK - do not use any third-party booking sites or apps
  • clear your browser history or cache (check your browser’s help section to find out how to do this)
  • use your browser’s private mode (sometimes called ‘incognito mode’)
  • try a different browser
  • try a different device
  • try a different network (for example, connect to wifi if you’re using mobile data)
  • turn off your VPN if you’re using one

If you still have problems booking a test or managing one that’s more than 10 working days away

If all of these do not help, email DVSA with:

  • the details from the error message
  • the steps that you have already tried

You also need to include 2 of the following 3 in your email:

  • your driving licence number
  • your theory test pass certificate number
  • your driving test booking reference
