If you are now learning to drive, you are told you must drive in the bus lane when it's out-of-hours
I've heard mixed messages about this. I had a few lessons 5 years ago, never went anywhere with them, but I do remember my instructor being absolutely insistent about driving in the bus lanes when you can, he'd really call me out for it if I didn't. Being then a very, very new learner, trying to read the times of operation on the signs among trying to do everything else was a bit much.
I'm doing some lessons just now, going for my licence this time, and my current instructor is much more relaxed about it. He's based up in the Currie test center area and his advice for doing the test up there at least is to stay out the things. There's no shortage of bus lanes, some with different times from another, and in his view you're better not taking the risk of getting caught out. If you have somewhere like the Calder road dual carriageways and the bus lane is both empty and available there's no issue with using the space. Very different to the usual case where you have stopped/parked cars, buses, bikes etc in the lane and you might find yourself cutting in only to have to come out again 10 seconds later.
