¿Qué indica una luz verde no intermitente en un semáforo circular para vehículos?

- AProhíbe girar a la derechaIt prohibits turning right
- BPermite el paso solo a peatonesIt allows only pedestrians to cross
- CPermite el paso con prioridad salvo excepcionesIt allows you to go with priority, with some exceptions
ExplanationA non-flashing circular green light means that you may go. As a general rule, you have priority over vehicles on the crossing road. However, the correct answer says “with some exceptions” because the General Traffic Regulations (Art. 59) prohibit entering a junction, even if the light is green, if traffic is so heavy that you are likely to end up stopped in the middle of the junction, obstructing other road users. So it allows you to go, but with that vital precaution.

Acera-bici (pavement cycle path): a cycle route marked on the pavement (the pedestrian area). 2. Carril-bici (cycle lane): a cycle route running alongside the carriageway (where cars travel), either one-way or two-way. 3. Pista-bici (cycle track): a cycle route separated from motor traffic, with its own route independent of the roads. So if the route is “on the pavement” (acera), its technical name includes that word.
