Arrow Painting Contractors

I appreciate that signs stating 'No Road Markings' are placed there prior to the work, and continue to be visible following the line painting, and until the arrows are painted,

the latter often done some time later.
 

So my questions are these, and only apply the period following the arrows being painted.:

 

1. Are the arrow painting contractors, as part of their SLA/contract, contracted to remove the No Road Markings signs following their part of the work? 

2. If not, why not?

3. If not practical to do this, is there a procedure in place to visit the site to remove the signs?

4. If not, why not?

I can confirm that the information requested is held by Lincolnshire County Council. I have detailed below the information that is being released to you. 

 1. Yes, the contractor is permitted to remove all applicable signage on completion.

2. See answer 1.

3. See answer 1.

4. See answer 1.
