That is, the correct answer is "Sign 1," considering that according to the definition in the Traffic Rules, sign 6.15 "Rest Area" informs about the location of an equipped rest area.

In this question, you need to identify the service sign that informs the driver that ahead or next to the road there is a specially equipped place where you can safely stop for a short rest.

According to section 33 of the Traffic Rules of Ukraine, sign 6.15 "Rest Area" is specifically intended to inform road users about the location of an equipped rest area. That is, it is not just "you can stop here," but an indication of the presence of appropriate infrastructure for rest.

Other similar signs in this group have a different purpose, so they are easy to distinguish by their meaning: sign 6.12 indicates where you can get drinking water, sign 6.9 points to an information service point, and sign 6.8 informs about the presence of a telephone. They do not mean a rest area, even though they also belong to service signs.

Therefore, the correct answer is "Sign 1," as it corresponds to sign 6.15 of the Traffic Rules of Ukraine and informs about the presence of an equipped rest area on the road.
