This petition was rejected

The Government e-Petitions Team gave the following reason:

Petitions need to call on the Government or Parliament to take a specific action.

We're not sure exactly what you'd like the Government or Parliament to do. Speed limits are set locally, within the limits of the National Speed Limits, which you can find here:

www.gov.uk/speed-limits

There's no specific limit for 'country lanes'. You could start a new petition explaining clearly what you would like the Government or Parliament to do, such as increase the national speed limit on single carriageways to 90mph, if that's what you'd like to see happen.
