According to the RA Law on Ensuring Road Traffic Safety, a traffic lane is considered to be:
The marked longitudinal lane of the traffic area, the width of which is sufficient for one-lane traffic.
Marked or unmarked longitudinal lane of the traffic area, the width of which is sufficient for one-lane traffic.✓Respuesta correcta
Explicación
A traffic lane is a longitudinal part of the carriageway wide enough for one line of vehicles, whether or not road markings outline it. Requiring visible markings would wrongly exclude lanes whose boundaries are determined from the usable width of the carriageway.
