Marc asked: How do you handle a deputy who tells you that must keep to the extreme right of a substandard roadway or ride on the sidewalk?
That depends on the circumstances.
If it is a drive-by announcement over the bullhorn, I suggest moving over until the deputy is past, then following the law that you seem to be familiar with, being aware that you might encounter the same officer later on. See the posts about Lane Width and Sharing
If you have been stopped and the deputy is present, IF it seems you can conduct a reasonable discussion, you might ask the deputy to show you the statute and point out the exceptions, asking if the lane in question is wide enough to safely share, that being at least 14 feet according to the Department of Transportation. See this post:
If you have a Law Enforcement Guide, a copy of the pertinent articles from this site or a smart phone, which you can use to show the site, point out the exceptions to the “keep right” regulation.
Such a discussion is usually not possible. You can ask to have a supervisor called to the scene, at which time you can ask the officers the wording and purpose of the narrow lane and other exceptions to the “keep right” provisions in the statute.
All of the above require that you be fully versed in the applicable laws and be able to quote the wording in the statute, so it is recommended that all cyclists study the information on this site, not just for a response to a law enforcement incident, but to be able to fully use the laws to ride safely.
It might be helpful for all cyclists to memorize the following question for use in such a situation:
What does Florida Statute 316.2065 Bicycle Regulations, subparagraph (5)(a)3 say about keeping right in substandard-width lanes?
As a last resort, you can challenge the officer to write a citation and pursue it through the legal system, being aware that you are taking a chance that the system will fail you as it has others. See this post:

In any event, we recommend that you insure you get the officer’s name, badge number or the number on the officer’s vehicle and write a letter to the police chief or Sheriff and explain the circumstances and the exact width of the lane in question, and quote the information on this site. Request that they consider a training program to educate the officers about this situation. Follow up to local bicycle clubs and other advocacy groups, the Bike/Ped Advisory Committee, city and county commissions and councils will also support the effort to have proper education programs in place.
