In Florida, and probably all of the USA, double solid yellow means do
not cross TO PASS. You are allowed to cross to turn, such as to make a
uturn.
To indicate do no cross you need a yellow median island.

Hi all,
Someone on the help site is questioning about a missing u-turn
restriction on a roundabout junction with splitter islands ([1] in
French). The problem is when you take one roundabout exit and want to
come back to the roundabout, a router like OSRM is telling you to
immediatly turn left
I think no_left_turn is the best solution. The line on the middle of the
street is not a u-turn indicator, it is an overtake indicator which can be
tagged with overtaking=no and overtaking=both.
Are you sure that the dotted overtake line allows you to make a u-turn?

Actually, no_u_turn would be better. It's the same for the router, but
not the same for the user interface.

Not sure about other countries, but in UK and NL a solid line means
(formally) no crossing and not no overtaking. For larger vehicles it
might be effectively the same thing, but for motorcycles (for example) it's
not as they can overtake another

Well, usually, a no-u-turn restriction is indicated at
intersections. The relation restriction in OSM is also desgined for
intersection nodes.

The router does need fixing however as U-turns around a roundabout divider
