The speed limit on narrow side roads is 60km/hr? I find that hard to believe...
It's the default for urban areas, so unless the limit is specifically lowered it's 60 km/h.
The actual speed "limit" on those streets is definitely no higher than 30km/h, regardless of what the signs say. If I drove 60 there I hope I'd lose my license for reckless driving.
>while speed limit in Moscow is 60 km/h.
Only when you are outside of apartments' territory.
